Description

Technical Field

[0001] This invention relates to the field of switch technology, and in particular to a switch and a computer system. Background Technology

[0002] As large model parameters increase from hundreds of billions to trillions and cluster sizes leap from thousands of cards to hundreds of thousands of cards, traditional copper cable-based interconnection solutions can no longer meet the demands. Switches using NPO (Near-Packaged Optics) technology have emerged to address this need. However, the design of switches using NPO technology is still in its early stages. Currently, switches using NPO technology support low density, requiring a large number of switches to interconnect in practical applications. This not only increases power consumption and latency but also significantly increases the amount of fiber optic cable used, resulting in high costs. Furthermore, a large number of switches occupy a significant amount of space, making actual deployment and maintenance very difficult. Summary of the Invention

[0003] This invention provides a switch that at least addresses the problems of low support density, increased power consumption, and higher latency in related technologies.

[0004] The switch according to the present invention includes: a plurality of first switching nodes and a plurality of second switching nodes, the first switching nodes and the second switching nodes are orthogonally arranged, each of the first switching nodes is electrically connected to the plurality of second switching nodes, the first switching nodes have external terminals, and the number of first switching nodes is greater than the number of second switching nodes.

[0005] The present invention also provides a computer system including the aforementioned switch and multiple servers, all of which are connected to the switch.

[0006] The switch layout of this application is reasonable, which can significantly improve the switch support density. A single or a small number of switches can meet the usage requirements without the need for a large number of interconnected devices. This helps to reduce power consumption and latency, and can also reduce the amount of fiber optic cable used, resulting in lower costs. Moreover, it occupies little space and is relatively easy to deploy and maintain. In addition, any first switching node is electrically connected to multiple second switching nodes, which can form a multi-path non-blocking forwarding path with better performance.

Detailed Implementation

[0010] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

Those skilled in the art will understand the specific meaning of the above terms in this application based on the specific circumstances.

[0012] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0013] The following is for reference. Figures 1-10 A switch 100 according to an embodiment of the present invention is described.

[0014] like Figures 1-3 , Figure 7 As shown, the switch 100 according to an embodiment of the present invention includes: a plurality of first switching nodes 20 and a plurality of second switching nodes 30.

[0015] As some embodiments of this application, the switch 100 further includes: a chassis 10, the chassis 10 defining a first direction (i.e. Figure 1 The first space 11 and the second space 12 are arranged along the X direction (as shown in the diagram). Specifically, the chassis 10 includes the first space 11 and the second space 12, arranged along the first direction (i.e., the X direction). Figure 1 (As shown in the X direction), the first space 11 and the second space 12 are arranged and correspondingly positioned.

[0016] Multiple first switching nodes 20 are disposed in the first space 11, and multiple second switching nodes 30 are disposed in the second space 12. The first switching nodes 20 and the second switching nodes are orthogonally arranged, for example, along the first direction (i.e., along the first direction). Figure 1 (in the X direction shown) The orthographic projection profile of any first exchange node 20 intersects with the orthographic projection profile of any second exchange node 30 and forms an angle. That is, the first exchange node 20 and the second exchange node 30 are not arranged in parallel. The first exchange node 20 and the second exchange node 30 can each include a node body 21 and other components disposed on the node body 21. The node body 21 can be constructed as a plate-like structure. The orthographic projection profile of the first exchange node 20 can be understood as the orthographic projection profile of the node body 21 of the first exchange node 20, and the orthographic projection profile of the second exchange node 30 can be understood as the orthographic projection profile of the node body 21 of the second exchange node 30.

[0017] It should be noted that the "perpendicularity" and "parallelism" described in this article refer to industrially achievable perpendicularity and parallelism, rather than absolute perpendicularity and parallelism in a mathematical sense. For example, if the angle between the orthographic projection profile of any first exchange node 20 and the orthographic projection profile of any second exchange node 30 is any value between 89 degrees and 91 degrees, then the first exchange node 20 and the second exchange node 30 can be considered to be orthogonally arranged. Alternatively, if the angle between any first exchange node 20 and any second exchange node 30 is any value between 89 degrees and 91 degrees, then the first exchange node 20 and the second exchange node 30 can be considered to be orthogonally arranged.

[0018] Each first switching node 20 is electrically connected to multiple second switching nodes 30. In some embodiments of this application, each first switching node 20 is electrically connected to some of the second switching nodes 30; in other embodiments, each first switching node 20 is electrically connected to all of the second switching nodes 30. Each first switching node 20 has an external connection 211, meaning that the first switching node 20 is an external switching node, and the second switching nodes 30 are internal switching nodes. The external connection 211 can be configured as an external interconnection interface, supporting more than 14 QDD (Quad Small Form-Factor Pluggable Double Density, a traditional high-speed optical module packaging standard for data centers) standard modules or ELSFP (External Laser Small Form-Factor Pluggable, an external laser source small pluggable module) modules.

[0019] It should be noted that this application includes the chassis 10 along the first direction (i.e., Figure 1 The first space 11 and the second space 12 are arranged in the X direction shown, and the first space 11 and the second space 12 are respectively used to accommodate the first exchange node 20 and the second exchange node 30, and the first exchange node 20 and the second exchange node 30 are arranged orthogonally or approximately orthogonally. This allows for a reasonable layout of the switch 100 proposed in this application, enabling high-density deployment, significantly improving the support density of the switch 100, and greatly enhancing the computing density. This allows a single or small number of switches 100 to meet usage requirements, and a single switch 100 can achieve full interconnection of a 100-card cluster without the need for multiple interconnections, which helps reduce power consumption and latency. Furthermore, since multiple interconnections are not required, the fiber optic cables between multiple devices can be omitted, reducing the amount of fiber optic cable used and lowering costs. Moreover, the high-density deployment allows for reduced space occupation while meeting the same requirements, making deployment and maintenance more convenient. In addition, by arranging the first switching node 20 and the second switching node 30 orthogonally or nearly orthogonally, and ensuring that each first switching node 20 is electrically connected to multiple second switching nodes 30, internal interconnection of the switch 100's switching nodes can be achieved, forming a multi-path, non-blocking forwarding path with superior performance. Furthermore, each first switching node 20 and each second switching node 30 supports independent maintenance.

[0020] Therefore, the switch 100 of this application has a reasonable layout, which can significantly improve the support density of the switch 100. A single or a small number of switches 100 can meet the usage requirements without the need for a large number of interconnected devices. This helps to reduce power consumption and latency, and can also reduce the amount of fiber optic application, resulting in lower cost. Moreover, it occupies little space and is relatively convenient to deploy and maintain. In addition, any first switching node 20 is electrically connected to multiple second switching nodes 30, which can form a multi-path non-blocking forwarding path with better performance.

[0021] In some embodiments of the present invention, such as Figure 1 As shown, the number of first switching nodes 20 is greater than the number of second switching nodes 30. That is, there are more first switching nodes 20 than second switching nodes 30. In some embodiments of this application, there are 16 first switching nodes 20 and 4 second switching nodes 30, with each second switching node 30 connected to all 16 first switching nodes 20. In some embodiments of this application, there are 12 first switching nodes 20 and 3 second switching nodes 30, with each second switching node 30 connected to all 12 first switching nodes 20.

[0022] By making the number of first switching nodes 20 greater than the number of second switching nodes 30, more external ports 211 can be configured, significantly increasing the capacity of the switch 100 to access external servers. A single device can support the interconnection needs of a cluster of hundreds of cards, eliminating the need for interconnection of multiple switches 100, reducing the amount of supporting fiber optic cables used, and lowering network latency and power consumption. At the same time, a small number of second switching nodes 30 can complete the internal interconnection of all first switching nodes 20. While ensuring multi-path non-blocking forwarding capability, it reduces the hardware investment in internal switching nodes, lowers the overall material cost and power consumption of the machine, and can further compress the space occupied by the second switching nodes 30 in terms of spatial layout, thereby increasing the overall integration density of the machine.

[0023] In some embodiments of the present invention, such as Figure 2 , Figure 3 As shown, the end of the first switching node 20 facing the second switching node 30 has a first connector 212, specifically, along the first direction (i.e. Figure 1 (As shown in the X direction), the end of the first switching node 20 facing the second space 12 has a first connector 212. The number of first connectors 212 is the same as that of the second switching nodes 30 and they correspond one-to-one. For example, there are four second switching nodes 30, and each first switching node 20 has four first connectors 212. The four first connectors 212 of each first switching node 20 correspond one-to-one with the four second switching nodes 30. For another example, there are six second switching nodes 30, and each first switching node 20 has six first connectors 212. The six first connectors 212 of each first switching node 20 correspond one-to-one with the six second switching nodes 30.

[0024] The second switching node 30 has a second connector 312 at the end facing the first switching node 20, specifically, along the first direction (i.e. Figure 1 (As shown in the X direction), the end of the second switching node 30 facing the first space 11 has a second connector 312. The number of second connectors 312 is the same as that of the first switching nodes 20 and they correspond one-to-one. For example, if there are sixteen first switching nodes 20, each second switching node 30 has sixteen second connectors 312, and the sixteen first connectors 212 of each second switching node 30 correspond one-to-one with the sixteen first switching nodes 20. Or, for another example, if there are fourteen first switching nodes 20, each second switching node 30 has fourteen second connectors 312, and the fourteen first connectors 212 of each second switching node 30 correspond one-to-one with the fourteen first switching nodes 20.

[0025] The first connectors 212 of the first switching node 20 are respectively connected to one of the second connectors 312 of the corresponding second switching node 30. For example, there are sixteen first switching nodes 20, each with four first connectors 212, and four second switching nodes 30, each with sixteen second connectors 312. The four first connectors 212 of each first switching node 20 correspond to the four second switching nodes 30, and the sixteen second connectors 312 of each second switching node 30 correspond to the sixteen second switching nodes 30. The four first connectors 212 of the first switching node 20 are respectively connected to one of the second connectors 312 of the corresponding second switching node 30, and the sixteen second connectors 312 of the second switching node 30 are respectively connected to one of the first connectors 212 of the corresponding first switching node 20.

[0026] For example, there are twelve first switching nodes 20, each with three first connectors 212, and three second switching nodes 30, each with twelve second connectors 312. The three first connectors 212 of each first switching node 20 correspond to the three second switching nodes 30, and the twelve second connectors 312 of each second switching node 30 correspond to the twelve second switching nodes 30. The three first connectors 212 of the first switching node 20 are connected to one of the second connectors 312 of the corresponding second switching node 30, and the twelve second connectors 312 of the second switching node 30 are connected to one of the first connectors 212 of the corresponding first switching node 20.

[0027] By setting multiple first connectors 212 matching the number of second switching nodes 30 at one end of the first switching node 20 facing the second switching node 30, and correspondingly setting second connectors 312 matching the number of first switching nodes 20 at one end of the second switching node 30 facing the first switching node 20, each first switching node 20 can be electrically connected to all second switching nodes 30, which can stably realize multi-path non-blocking forwarding paths with better performance. Moreover, each first connector 212 has a corresponding second connector 312, and each communication path is physically isolated, which can effectively suppress signal crosstalk and ensure the quality of high-speed signal transmission. In addition, each first connector 212 has a corresponding second connector 312, which can achieve precise blind mating during assembly, ensuring the reliability of the mating connection, and also facilitating the assembly of the switch 100.

[0028] In some embodiments of the present invention, such as Figure 1 As shown, multiple first switching nodes 20 are along the second direction (i.e. Figure 1 The multiple first switching nodes 20 are arranged sequentially along the Y direction (as shown), and any two adjacent first switching nodes 20 are arranged in parallel; in other words, the multiple first switching nodes 20 are arranged in parallel with each other. The multiple second switching nodes 30 are arranged along a third direction (i.e., along the Y direction). Figure 1 The multiple second exchange nodes 30 are arranged sequentially in the Z direction (as shown), and any two adjacent second exchange nodes 30 are arranged in parallel. In other words, the multiple second exchange nodes 30 are arranged in parallel with each other. Any two of the first, second, and third directions are perpendicular.

[0029] By causing multiple first switching nodes 20 to move along the second direction (i.e. Figure 1 Multiple second exchange nodes 30 are arranged in parallel along the Y direction (as shown), and along the third direction (i.e. Figure 1 The switches 100 are arranged in parallel along the Z-direction (as shown), making full use of the internal space of the chassis 10. This arrangement can accommodate more switching nodes in a limited space, resulting in a reasonable layout that significantly improves support density. A single or a small number of switches 100 can meet the usage requirements. Moreover, this layout ensures that each first switching node 20 and each second switching node 30 will not structurally interfere with adjacent first switching nodes 20 and second switching nodes 30 during insertion and removal operations. Operators can remove any switching node individually for replacement or maintenance, allowing for convenient operation even in high-density, confined spaces.

[0030] As some embodiments of this application, a third party (i.e.) Figure 1 The Z direction shown is the height direction of switch 100.

[0031] In some embodiments of the present invention, such as Figure 1 , Figure 2 , Figure 10 As shown, along the first direction (i.e. Figure 1 (as shown in the X direction), the end of the first switching node 20 furthest from the second switching node 30 has an external terminal 211. That is, along the first direction (i.e., Figure 1 (As shown in the X direction), the first switching node 20 has an external terminal 211 at one end facing the outside of the chassis 10.

[0032] This application sets the external terminal 211 in the first switching node 20 along the first direction (i.e., Figure 1 The external connector 211 is positioned outwards from the end of the first switching node 20 (in the X direction shown), allowing external optical fibers and server cables to be directly plugged into the outside of the chassis 10 without needing to enter the chassis 10. This provides ample space for wiring and facilitates installation. Furthermore, the external connector 211 and the connector on the first switching node 20 used to connect to the second switching node 30 are located at opposite ends, physically separating the internal and external signal areas. External wiring will not interfere with the orthogonal connection between the first switching node 20 and the second switching node 30, which helps ensure the stability of the internal interconnection. In addition, the external layout of the external connector 211 facilitates intuitive viewing, and fault location and line replacement do not require disassembling the chassis 10, further reducing the difficulty of deploying and maintaining the switch 100.

[0033] In some embodiments of the present invention, such as Figure 1 , Figure 2 , Figure 10 As shown, the first switching node 20 has a plurality of external terminals 211. The number of external terminals 211 of the first switching node 20 can be, but is not limited to, 8, 12, 14, etc. As some embodiments of this application, at least one first switching node 20 has 14 external terminals 211. The plurality of external terminals 211 are along a third direction (i.e., Figure 1 The multiple first switching nodes 20 are arranged along the second direction (i.e., the Z direction shown). Figure 1 Arranged in the Y direction as shown, multiple external terminals 211 on a first switching node 20 are arranged along a third direction (i.e., Figure 1 Arrangement in the Z direction as shown.

[0034] This configuration allows for efficient use of space on multiple external ports 211 on a single first switching node 20, facilitating the integration of more external ports 211 on a single first switching node 20. This further enhances the external access density of the switch 100, better meeting the access needs of massive servers in large-scale computing power clusters. At the same time, this configuration allows multiple external ports 211 on multiple first switching nodes 20 to be arranged neatly and orderly, with orderly layering of external plug-in wiring. Cables are less likely to become tangled and interfere with each other, making on-site wiring and line troubleshooting more convenient and facilitating quick identification and operation by maintenance personnel.

[0035] In some embodiments of the present invention, such as Figure 1 , Figure 7 , Figure 8 As shown, the switch 100 also includes: a mounting bracket 50 and a conductive component 60. Along the first direction, the mounting bracket 50 is disposed between the first space 11 and the second space 12. That is, the mounting bracket 50 is disposed between multiple first switching nodes 20 and multiple second switching nodes 30. The mounting bracket 50 can be connected to the chassis 10.

[0036] As some embodiments of this application, the switch 100 further includes: a power supply module 40, which is disposed inside the chassis 10 and electrically connected to the conductive component 60. The power supply module 40 can be one or more. As some embodiments of this application, the switch 100 also includes: a main power board 41, which is disposed on one side of the power supply module 40 and electrically connected to it. For example, along the height direction of the switch 100, the power supply module 40 is disposed above the second space 12, and the main power board 41 is disposed on the side of the power supply module 40 facing the first space 11 along the first direction. This layout is reasonable and has high space utilization.

[0037] The conductive component 60 is mounted on the mounting bracket 50 and electrically connected to both the first switching node 20 and the second switching node 30. The conductive component 60 can be configured as a busbar. The conductive component 60 can be mounted on the mounting bracket 50 by means of, but not limited to, riveting, welding, bolting, snap-fitting, etc. The conductive component 60 is electrically connected to both the first switching node 20 and the second switching node 30. The power supply module 40 can supply power to the first switching node 20 and the second switching node 30 through the conductive component 60.

[0038] This application arranges the mounting bracket 50 between multiple first switching nodes 20 and multiple second switching nodes 30, and integrates the conductive component 60 on the mounting bracket 50. The conductive component 60 can be connected to the first switching nodes 20 and the second switching nodes 30 on both sides respectively, without the need to lay out power supply components for each switching node, avoiding the space occupied by a large number of power supply components, which is conducive to arranging more first switching nodes 20 and second switching nodes 30. Moreover, it also shortens the power supply path and ensures the stable power supply of high-speed switching nodes. In addition, it can make full use of the space gap between multiple first switching nodes 20 and multiple second switching nodes 30, with extremely high space utilization, which is conducive to ensuring the structural advantages of high-density deployment of the switch 100.

[0039] In some embodiments of the present invention, such as Figure 8 , Figure 9As shown, the end of the first switching node 20 facing the second switching node 30 has a first connector 212, and the end of the second switching node 30 facing the first switching node 20 has a second connector 312 corresponding to the first connector 212. The mounting bracket 50 has a clearance hole 59, through which at least one of the first connector 212 and the corresponding second connector 312 can pass and connect. This arrangement allows the mounting bracket 50 itself to provide a passage for the first connector 212 and the corresponding second connector 312, eliminating the need for additional independent insertion and assembly space, which is beneficial for achieving a miniaturized and compact design of the switch 100.

[0040] In some embodiments of the present invention, such as Figure 8 , Figure 9 As shown, the mounting bracket 50 includes a bracket body 51 and a first power supply board 52. The first power supply board 52 is connected to the bracket body 51. For example, the first power supply board 52 is connected to the side of the bracket body 51 facing the first switching node 20. As some embodiments of this application, the first power supply board 52 can be disposed on the surface of the bracket body 51 facing the surface by means of, but not limited to, riveting, welding, bolting, snap-fitting, etc. The first power supply board 52 has a first power supply 521 facing the first switching node 20 and a second power supply 522 facing the second switching node 30. The first power supply 521 is electrically connected to the first switching node 20, and the second power supply 522 is electrically connected to the conductive element 60. As some embodiments of this application, the first switching node 20 has a sixth power supply 215, which can be electrically connected to the first power supply 521. The number of first power supplies 521 can be the same as the number of first switching nodes 20 and correspond one-to-one. The first power supply 521 can be electrically connected to the sixth power supply 215 of the corresponding first switching node 20. The power supply module 40 can supply power to the first switching node 20 through the conductive component 60 and the first power supply board 52.

[0041] This configuration allows the first power supply board 52 of the mounting bracket 50 to establish a power supply path between the first switching node 20 and the conductive component 60, making full use of the space between multiple first switching nodes 20 and multiple second switching nodes 30. Furthermore, by connecting the first power supply board 52 to the side of the bracket body 51 facing the first switching node 20, it facilitates the electrical connection between the first switching node 20 and the first power supply board 52. Moreover, the first power supply unit 521 and the second power supply unit 522 are integrated on the same first power supply board 52, which helps to ensure a balanced and stable power supply to each first switching node 20 and enables standardized integrated assembly, eliminating the need for scattered power supply wiring and adapting to the high-density layout design of the entire machine.

[0042] In some embodiments of the present invention, such as Figure 8As shown, the number of first power supply units 521 is the same as the number of first switching nodes 20 and corresponds one-to-one. Multiple first power supply units 521 and multiple first switching nodes 20 are arranged along the second direction, which is perpendicular to the first direction. This arrangement makes the arrangement of multiple first power supply units 521 and multiple first switching nodes 20 reasonable, the structure compact, the space utilization rate high, and it is suitable for the high-density layout design of the whole machine.

[0043] In some embodiments of the present invention, such as Figure 7 , Figure 8 , Figure 9 As shown, the switch 100 also includes a management module 70, and the mounting bracket 50 also includes a second power supply board 53. The second power supply board 53 and the first power supply board 52 are connected to the same side of the bracket body 51. That is, the second power supply board 53 is connected to the side surface of the bracket body 51 facing the first switching node 20. As some embodiments of this application, the second power supply board 53 can be provided on the side surface of the bracket body 51 facing the first switching node 20 by means of riveting, welding, bolting, snap-fitting, etc. The second power supply board 53 has a third power supply 531 facing the first switching node 20 and a fourth power supply 532 facing the second switching node 20. The third power supply 531 is electrically connected to the management module 70, and the fourth power supply 532 is electrically connected to the conductive element 60. The conductive element 60 can supply power to the management module 70 through the conductive element 60 and the second power supply board 53.

[0044] This configuration allows the management module 70 to establish a power supply path between the conductive component 60 and the second power supply board 53 of the mounting bracket 50, making full use of the space between the multiple first switching nodes 20 and the multiple second switching nodes 30. Furthermore, by connecting the second power supply board 53 to the side of the bracket body 51 facing the first switching node 20, it facilitates the electrical connection between the management module 70 and the second power supply board 53. Moreover, the third power supply unit 531 and the fourth power supply unit 532 are integrated on the same second power supply board 53, which can achieve standardized integrated assembly, eliminating the need for scattered power supply components and adapting to the high-density layout design of the whole machine.

[0045] As some embodiments of this application, multiple management modules 70 can be configured to achieve redundancy and reduce the risk of switch 100 downtime due to failure of a certain management module 70.

[0046] In some embodiments of the present invention, such as Figure 7 , Figure 8 , Figure 9As shown, the conductive element 60 is connected to the side of the bracket body 51 facing the second exchange node 30. The bracket body 51 has a clearance through hole 511. The second power supply 522 and the fourth power supply 532 both pass through the clearance through hole 511 and are electrically connected to the conductive element 60. This arrangement can make full use of the space on both sides of the bracket body 51 to arrange other components, making reasonable use of space. Moreover, the clearance through hole 511 not only allows the first power supply board 52 and the second power supply board 53 located on one side of the bracket body 51 to be electrically connected to the conductive element 60 located on the other side of the bracket body 51, but also provides positioning constraints for the second power supply 522 of the first power supply board 52 and the fourth power supply 532 of the second power supply board 53, improving installation accuracy.

[0047] In some embodiments of the present invention, such as Figure 1 , Figure 7 As shown, the switch 100 also includes a power supply module 40, wherein the management module 70 is located inside the chassis 10 and is electrically connected to the conductive component 60. Along the height direction of the switch 100, the management module 70 is located above a plurality of first switching nodes 20, and the power supply module 40 is located above a plurality of second switching nodes 30. That is, the management module 70 is located above the first space 11, and the power supply module 40 is located above the second space 12. The power supply module 40 is electrically connected to the conductive component 60.

[0048] This application places the management module 70 above multiple first switching nodes 20 and the power supply module 40 above multiple second switching nodes 30. The management module 70 and the power supply module 40 are arranged in zones and are electrically connected through conductive parts 60. This facilitates the hierarchical and zoned layout of the internal functional areas of the switch 100, makes full use of the top space of the switch 100, does not occupy the core space used to arrange switching nodes, and has a reasonable layout and high space utilization.

[0049] In some embodiments of the present invention, such as Figure 8 As shown, the second power supply board 53 also has multiple third connectors 533 and fifth connectors 58 facing the first switching node 20. The number of third connectors 533 is the same as that of the first switching node 20 and they correspond one-to-one. The end of the first switching node 20 facing the second switching node 30 has a fourth connector 213 that is electrically connected to the corresponding third connector 533. The end of the management module 70 facing the second switching node 30 has a sixth connector 71 that is electrically connected to the fifth connector 58. This arrangement allows the second power supply board 53 to not only supply power to the management module 70, but also to realize the signal interconnection between the management module 70 and the first switching node 20. This achieves integrated deployment of power supply and signal paths, eliminating the need for separate signal transmission components within the chassis 10. This effectively reduces the number of internal components in the chassis 10, avoids occupying limited internal space, and ensures the advantages of the high-density layout of the switch 100.

[0050] In some embodiments of the present invention, such as Figure 3 As shown, multiple third connectors 533 and multiple fifth connectors 58 are arranged along the second direction, and the third connectors 533 and fifth connectors 58 are arranged along the third direction. The second direction is perpendicular to both the first direction and the third direction. This arrangement makes the arrangement of multiple third connectors 533 and multiple fifth connectors 58 reasonable, the structure compact, and the space utilization high, which is suitable for the high-density layout design of the whole machine.

[0051] In some embodiments of the present invention, such as Figure 3 As shown, the second switching node 30 has a plurality of second connectors 312 arranged in sequence and at least one fifth power supply 33 at the end facing the first switching node 20. The second connectors 312 are configured for electrical connection with the first switching node 20.

[0052] The first switching node 20 has a first connector 212 at the end facing the second switching node 30, specifically, along the first direction (i.e., Figure 1 (As shown in the X direction), the end of the first switching node 20 facing the second space 12 has a first connector 212. The number of first connectors 212 is the same as that of the second switching nodes 30 and they correspond one-to-one. For example, there are four second switching nodes 30, and each first switching node 20 has four first connectors 212. The four first connectors 212 of each first switching node 20 correspond one-to-one with the four second switching nodes 30. For another example, there are six second switching nodes 30, and each first switching node 20 has six first connectors 212. The six first connectors 212 of each first switching node 20 correspond one-to-one with the six second switching nodes 30.

[0053] The second switching node 30 has a second connector 312 at the end facing the first switching node 20, specifically, along the first direction (i.e. Figure 1 (As shown in the X direction), the end of the second switching node 30 facing the first space 11 has a second connector 312. The number of second connectors 312 is the same as that of the first switching nodes 20 and they correspond one-to-one. For example, if there are sixteen first switching nodes 20, each second switching node 30 has sixteen second connectors 312, and the sixteen first connectors 212 of each second switching node 30 correspond one-to-one with the sixteen first switching nodes 20. Or, for another example, if there are fourteen first switching nodes 20, each second switching node 30 has fourteen second connectors 312, and the fourteen first connectors 212 of each second switching node 30 correspond one-to-one with the fourteen first switching nodes 20.

[0054] The first connectors 212 of the first switching node 20 are respectively connected to one of the second connectors 312 of the corresponding second switching node 30. For example, there are sixteen first switching nodes 20, each with four first connectors 212, and four second switching nodes 30, each with sixteen second connectors 312. The four first connectors 212 of each first switching node 20 correspond to the four second switching nodes 30, and the sixteen second connectors 312 of each second switching node 30 correspond to the sixteen second switching nodes 30. The four first connectors 212 of the first switching node 20 are respectively connected to one of the second connectors 312 of the corresponding second switching node 30, and the sixteen second connectors 312 of the second switching node 30 are respectively connected to one of the first connectors 212 of the corresponding first switching node 20.

[0055] For example, there are twelve first switching nodes 20, each with three first connectors 212, and three second switching nodes 30, each with twelve second connectors 312. The three first connectors 212 of each first switching node 20 correspond to the three second switching nodes 30, and the twelve second connectors 312 of each second switching node 30 correspond to the twelve second switching nodes 30. The three first connectors 212 of the first switching node 20 are connected to one of the second connectors 312 of the corresponding second switching node 30, and the twelve second connectors 312 of the second switching node 30 are connected to one of the first connectors 212 of the corresponding first switching node 20.

[0056] The end of the second switching node 30 facing the first switching node 20 also has at least one fifth power supply 33. That is, the end of the second switching node 30 facing the first switching node 20 may have one fifth power supply 33, or the end of the second switching node 30 facing the first switching node 20 may have multiple fifth power supply 33s. Along the first direction, at least a portion of the orthographic projection of the fifth power supply 33 is located between a set of two adjacent second connectors 312. The conductive element 60 is connected to the side surface of the mounting bracket 50 facing the second space 12, and a portion of the conductive element 60 is inserted through the gap between a set of two adjacent second connectors 312 and electrically connected to the fifth power supply 33.

[0057] This arrangement can make full use of the originally unused gap between adjacent second connectors 312 on the second switching node 30 for the conductive component 60 to pass through, so as to realize the electrical connection between the conductive component 60 and the fifth power supply 33 without taking up the arrangement space of the second connector 312, and without affecting the orthogonal layout and connection between the second switching node 30 and the first switching node 20, thus ensuring the advantages of the high-density layout of the switch 100.

[0058] In some embodiments of the present invention, such as Figure 2 , Figure 8 As shown, the end of the first switching node 20 facing the second switching node 30 has multiple first connectors 212 and multiple sixth power supplies 215. The first connectors 212 are configured for electrical connection with the second switching node 30, and the sixth power supplies 215 are configured for electrical connection with the first power supply 521. The first connectors 212, sixth power supplies 215, and fourth connectors 213 of the same first switching node 20 are all arranged along a third direction, and the orthographic projections of the first connectors 212, sixth power supplies 215, and fourth connectors 213 of the same first switching node 20 along the third direction have overlapping areas. This arrangement allows all devices connecting the first switching node 20 to the internal components of the switch 100 to be located at the same end of the first switching node 20, facilitating connection between the first switching node 20 and the internal components of the switch 100. Moreover, the arrangement is reasonable, the structure is compact, the space utilization is high, and it is suitable for the high-density layout design of the entire machine.

[0059] In some embodiments of the present invention, such as Figure 2 , Figure 8 As shown, a first positioning part 54 is formed on the side of the mounting bracket 50 facing the first switching node 20. There are multiple first positioning parts 54. The first positioning parts 54 can be formed on the bracket body 51, or they can be formed on the first power supply board 52 and / or the second power supply board 53. The first switching node 20 has the same number of second positioning parts 214 as the first positioning parts 54, each providing a one-to-one positioning fit. One of the first positioning parts 54 and the second positioning parts 214 can be configured as a positioning pin, and the other can be configured as a positioning hole. This configuration improves the installation accuracy of the first switching node 20 and facilitates blind insertion of the first switching node 20, thus improving the ease of assembly of the switch 100. The second positioning part 214, the first connector 212, the sixth power supply 215, and the fourth connector 213 of the same first switching node 20 are all arranged along a third direction, and the orthographic projections of the second positioning part 214, the first connector 212, the sixth power supply 215, and the fourth connector 213 of the same first switching node 20 along the third direction have overlapping areas. This arrangement allows for a reasonable and compact arrangement of the second positioning part 214, the first connector 212, the sixth power supply 215, and the fourth connector 213 of the same first switching node 20, with high space utilization, making it suitable for high-density layout designs of the entire machine.

[0060] In some embodiments of the present invention, such as Figure 3 , Figure 9As shown, a third positioning part 55 is formed on the side of the mounting bracket 50 facing the second switching node 30, and the second switching node 30 has a fourth positioning part 34, which is the same number as the third positioning part 55 and is positioned and matched one by one. There are multiple third positioning parts 55, which can be formed on the bracket body 51. One of the third positioning part 55 and the fourth positioning part 34 can be configured as a positioning pin, and the other can be configured as a positioning hole. This arrangement can improve the installation accuracy of the second switching node 30 and facilitate blind insertion of the second switching node 30, improving the assembly convenience of the switch 100. Furthermore, at least one fourth positioning part 34 is located between two adjacent second connectors 312. As some embodiments of this application, all fourth positioning parts 34 are located between two adjacent second connectors 312. This arrangement allows for a reasonable arrangement of the fourth positioning parts 34 and second connectors 312 of the same second switching node 30, resulting in a compact structure, high space utilization, and suitability for high-density layout designs of the entire machine.

[0061] As some embodiments of this application, such as Figure 8 As shown, a fifth positioning part 57 is formed on the side of the mounting bracket 50 facing the first space 11. There are multiple fifth positioning parts 57. The fifth positioning parts 57 can be formed on the bracket body 51 or on the second power supply board 53. The management module 70 has a sixth positioning part that can be positioned and engaged with the fifth positioning parts 57. One of the fifth and sixth positioning parts can be configured as a positioning pin, and the other can be configured as a positioning hole. This configuration improves the installation accuracy of the management module 70 and facilitates blind insertion of the management module 70, thus improving the ease of assembly of the switch 100.

[0062] In some embodiments of the present invention, such as Figure 8 , Figure 9 As shown, the mounting bracket 50 has at least one heat dissipation hole 56. That is, the mounting bracket 50 can have one heat dissipation hole 56 or multiple heat dissipation holes 56.

[0063] As some embodiments of this application, the bracket body 51 may have at least one heat dissipation hole 56. As some embodiments of this application, the bracket body 51 and the first power supply board 52 may jointly have at least one heat dissipation hole 56, that is, at least one heat dissipation hole 56 penetrates the bracket body 51 and the first power supply board 52. As some embodiments of this application, the bracket body 51 and the second power supply board 53 may jointly have at least one heat dissipation hole 56, that is, at least one heat dissipation hole 56 penetrates the bracket body 51 and the second power supply board 53.

[0064] The mounting bracket 50 is disposed between the first space 11 and the second space 12. By forming at least one heat dissipation hole 56 in the mounting bracket 50, the heat dissipation hole 56 can connect the first space 11 and the second space 12, so as to facilitate smooth airflow and improve the heat dissipation effect. Furthermore, it can allow the heat dissipation airflow generated by the air supply component 32 to flow smoothly between the first space 11 and the second space 12, avoiding airflow obstruction and local heat accumulation caused by the mounting bracket 50 blocking the air duct, effectively improving the heat dissipation efficiency of the switch 100, and reducing the risk of performance degradation and transmission instability of the first switching node 20 and the second switching node 30 due to long-term high-temperature operation.

[0065] Along the first direction, the heat dissipation through-hole 56 corresponds to the gap between at least one pair of adjacent first switching nodes 20, and / or, the heat dissipation through-hole 56 corresponds to the gap between at least one pair of adjacent second switching nodes 30. This arrangement can form a through-flow heat dissipation path, allowing airflow to pass directly through the node gaps and flow smoothly between the first space 11 and the second space 12 via the heat dissipation through-hole, reducing the area of ​​the mounting bracket 50 that obstructs airflow and significantly improving the heat dissipation efficiency of the switch 100.

[0066] As some embodiments of this application, at least a portion of the orthographic projection of the second power supply board 53 along the first direction can be located between the orthographic projections of the two second switching nodes 30. This arrangement allows the second power supply board 53 to be arranged using the gap between the two second switching nodes 30, resulting in reasonable space utilization.

[0067] It is understandable that the switch 100 proposed in this application can achieve complete internal cabling and has the advantages of high density, high compatibility, and high maintainability.

[0068] It should be noted that the first switching node 20 can be designed to match different external devices according to actual needs, and has great upgrade potential.

[0069] It should be noted that the mounting bracket integrates structural reinforcement, positioning, and power supply functions, which is beneficial to ensuring the structural advantages of 100 high-density deployment of switches. It should be noted that the connectors, power supplies, external terminals 211 and other connecting components described in this application may be one or multiple in physical form. For example, the fifth connector 58 may be one connector or multiple sub-connectors. The same applies to the other components, which will not be described in detail here.

[0070] In some embodiments of the present invention, such as Figure 3As shown, the switch 100 also includes: an air supply component 32, and at least one air supply component 32 is provided at the end of the second switching node 30 away from the first switching node 20. As some embodiments of this application, along the first direction (i.e. Figure 1 (as shown in the X direction), the second switching node 30 is provided with an air supply element 32 at the end away from the first switching node 20. As some embodiments of this application, along the first direction (i.e. Figure 1 (As shown in the X direction), the second exchange node 30 is provided with a plurality of air supply components 32 at the end away from the first exchange node 20, and the plurality of air supply components 32 are arranged along the second direction.

[0071] The air supply component 32 is configured to supply air toward the first exchange node 20. The air supply component 32 may be constructed as, but is not limited to, a fan, a blower, etc.

[0072] This application provides an air supply component 32 at the end of the second switching node 30 away from the first switching node 20, and directs the air supply component 32 toward the first switching node 20. This allows for simultaneous heat dissipation of the second switching node 30 and the first switching node 20, effectively reducing the operating temperature of the switch 100. Furthermore, the air supply component 32 is integrated into the end of the second switching node 30, allowing for easy plugging and unplugging and maintenance along with the second switching node 30. No additional space is required inside the chassis 10 for the air supply component 32, which is beneficial for achieving a high integration density layout of the switch 100.

[0073] In some embodiments of the present invention, such as Figures 4-6 As shown, the first switching node 20 and / or the second switching node 30 include: a node body 21 and a disassembly / assembly mechanism 22. As some embodiments of this application, the first switching node 20 includes: a node body 21 and a disassembly / assembly mechanism 22. As some embodiments of this application, the second switching node 30 includes: a node body 21 and a disassembly / assembly mechanism 22. As some embodiments of this application, both the first switching node 20 and the second switching node 30 include: a node body 21 and a disassembly / assembly mechanism 22.

[0074] like Figure 4 As shown, along a direction parallel to the node body 21 and perpendicular to the first direction, at least one side of the node body 21 is provided with a disassembly and assembly mechanism 22, which is configured to selectively lock with the chassis 10.

[0075] As some embodiments of this application, a plurality of first switching nodes 20 are along a second direction (i.e., Figure 1 The multiple second exchange nodes 30 are arranged sequentially along the Y direction (as shown), and along the third direction (i.e. Figure 1 The Z-direction shown is arranged sequentially, and any two of the first, second, and third directions are perpendicular.

[0076] In the first switching node 20, the node body 21 is provided with a disassembly and assembly mechanism 22 on at least one side along a third direction. For example, the node body 21 is provided with a disassembly and assembly mechanism 22 on one or both sides along a third direction. In the second switching node 30, the node body 21 is provided with a disassembly and assembly mechanism 22 on at least one side along a second direction. For example, the node body 21 is provided with a disassembly and assembly mechanism 22 on one or both sides along a second direction.

[0077] It should be explained that in the first exchange node 20, the external terminal 211, the first connector 212, and other parts are all formed in the node body 21. In the second exchange node 30, the second connector 312 and other parts are all formed in the node body 21. The air supply component 32 can be located in the node body 21.

[0078] This arrangement allows for a reasonable placement of the disassembly and assembly mechanism 22, without occupying the space for the interfaces and connectors on the corresponding switching nodes, nor obstructing the interfaces and connectors on the corresponding switching nodes. This facilitates the placement of more interfaces and connectors on the switching nodes, resulting in a compact structure that is compatible with the high-density layout design of the entire machine. Furthermore, it prevents other parts from obstructing the disassembly and assembly mechanism 22, making disassembly and assembly operations easier.

[0079] In some embodiments of the present invention, such as Figures 4-6 As shown, the disassembly and assembly mechanism 22 includes: mounting bracket 221, first locking member 222, and control member 223. The mounting bracket 221 is disposed on the node body 21. As some embodiments of this application, the mounting bracket 221 can be disposed on the node body 21 by means of welding, bolt connection, snap-fit, riveting, etc. The first locking member 222 is movably disposed on the mounting bracket 221 and configured to lock or unlock with the chassis 10. That is, the first locking member 222 is disposed on the mounting bracket 221 and can move relative to the mounting bracket 221. For example, the first locking member 222 can move or rotate relative to the mounting bracket 221. By moving the first locking member 222, the first locking member 222 can be locked or unlocked with the chassis 10. It can be understood that if the first locking member 222 is locked with the chassis 10, since the first locking member 222 is disposed on the mounting bracket 221 and the mounting bracket 221 is disposed on the node body 21, the node body 21 cannot be moved out of the chassis 10. In other words, if the first locking member 222 is locked with the chassis 10, the switching node is locked. Conversely, if the first locking member 222 is unlocked with the chassis 10, the node body 21 can be moved out of the chassis 10.

[0080] The control element 223 is movably disposed on the mounting bracket 221 and is linked with the first locking element 222. That is to say, the control element 223 is disposed on the mounting bracket 221 and can move relative to the mounting bracket 221. For example, the control element 223 can move or rotate relative to the mounting bracket 221, and the control element 223 is linked with the first locking element 222. The control element 223 can be directly linked with the first locking element 222, or the control element 223 can be indirectly linked with the first locking element 222. The linkage between the control element 223 and the first locking element 222 can be understood as controlling the movement of the control element 223 to control the movement of the first locking element 222.

[0081] The control element 223 is configured to lock or unlock the first locking element 222 with the chassis 10. Specifically, the control element 223 can be operated to unlock the first locking element 222 from the chassis 10 so that the node body 21 can be moved out of the chassis 10. Conversely, the control element 223 can be operated to lock the first locking element 222 with the chassis 10 so that the node body 21 moved into the chassis 10 is securely installed.

[0082] This configuration allows the first locking element 222 to lock and unlock with the chassis 10 simply by operating the control element 223. In the confined installation space of the high-density deployment of the switch 100, locking and unlocking of the switching node can be completed without additional tools. This ensures that the switching node is reliably locked inside the chassis 10 during the operation of the switch 100, reducing the risk of loosening of the connection between the switching node and other components due to vibration in the computer room or external pulling, thus improving connection reliability. It also simplifies the disassembly and maintenance steps of the switching node, further enhancing the convenience of disassembly and maintenance.

[0083] In some embodiments of the present invention, such as Figure 5 , Figure 6 As shown, the chassis 10 has a first locking engagement portion 13. The first locking engagement portion 13 can be constructed as a engagement pin, engagement protrusion, etc. The first locking member 222 is rotatably disposed on the mounting bracket 221 and configured to lock or unlock with the first locking engagement portion 13. For example, the first locking member 222 is rotatably disposed on the mounting bracket 221 via a pivot. By rotating the first locking member 222, the first locking member 222 can be locked or unlocked with the first locking engagement portion 13, so that the first locking member 222 is locked or unlocked with the chassis 10.

[0084] The control element 223 is configured to control the rotation of the first locking element 222, so as to lock or unlock the first locking element 222 and the first locking engagement part 13. This configuration allows the control element 223 to control the rotation of the first locking element 222, so as to switch between locking and unlocking the first locking element 222 and the first locking engagement part 13. The rotating first locking element 222 is stable and reliable, which can effectively reduce the risk of locking failure caused by vibration of the computer room, external pulling force, etc. Moreover, the rotating first locking element 222 requires a small space envelope, which is suitable for the high integration density layout of the switch 100.

[0085] In some embodiments of the present invention, such as Figure 5 , Figure 6 As shown, the control member 223 is movably disposed on the mounting bracket 221 along the first direction and has a drive portion 2231. As some embodiments of this application, the mounting bracket 221 defines a sliding space extending along the first direction. The control member 223 is disposed in the sliding space and can move along the first direction. The control member 223 has a drive portion 2231. The first locking member 222 has a mating portion 2221 that cooperates with the drive portion 2231. The drive portion 2231 is configured to drive the mating portion 2221 to rotate during movement along the first direction, so as to control the rotation of the first locking member 222.

[0086] As some embodiments of this application, the drive unit 2231 can be configured as a slide rail, and the drive mating part 2221 can be configured as a protrusion that mates with the slide rail. The slide rail can extend obliquely along a first direction. With this configuration, when the control member 223 moves along the first direction, the drive unit 2231, in conjunction with the drive mating part 2221, can control the rotation of the first locking member 222, thereby locking or unlocking the first locking member 222 with the first locking mating part 13, and locking or unlocking the first locking member 222 with the chassis 10.

[0087] As some embodiments of this application, during the movement of the control member 223 and its gradual extension out of the chassis 10, it can drive the first locking member 222 and the first locking engagement part 13 to unlock, so that the operator can pull out the control member 223 to unlock the corresponding switching node from the chassis 10, facilitating the removal of the corresponding switching node. During the movement of the control member 223 and its gradual extension into the chassis 10, it can drive the first locking member 222 and the first locking engagement part 13 to lock, so that the operator can push the control member 223 inward to lock the corresponding switching node from the chassis 10, facilitating the secure installation of the corresponding switching node. Moreover, this arrangement can convert the linear movement of the control member 223 along the first direction into the rotational movement of the first locking member 222. In a small space with multiple switching nodes densely arranged, locking and unlocking control can be completed simply by pushing and pulling the control member 223 along the first direction, without the need for large-scale twisting operations. This adapts to the limited operating space of the high-density switch 100, and the structural design is ingenious.

[0088] In some embodiments of the present invention, such as Figure 5 , Figure 6 As shown, the disassembly and assembly mechanism 22 also includes a second locking member 224, which is movably disposed on the control member 223 and configured to lock or unlock with the mounting bracket 221.

[0089] In other words, the second locking member 224 is disposed on the control member 223 and can move relative to the control member 223. For example, the second locking member 224 can move or rotate relative to the control member 223. By moving the second locking member 224, the second locking member 224 can be locked or unlocked with the mounting bracket 221. It can be understood that if the second locking member 224 is locked with the mounting bracket 221, since the second locking member 224 is disposed on the control member 223, the control member 223 cannot move relative to the mounting bracket 221. In other words, if the second locking member 224 is locked with the mounting bracket 221, the corresponding control member 223 is locked. Conversely, if the second locking member 224 is unlocked with the mounting bracket 221, the corresponding control member 223 can move relative to the mounting bracket 221.

[0090] This configuration allows the operator to lock the control component 223 to the mounting bracket 221 using the second locking component 224 after the first locking component 222 is engaged with the chassis 10. This reduces the risk of accidental displacement of the control component 223 and prevents it from shifting due to vibrations or accidental scraping during switch operation. It also prevents the first locking component 222 from accidentally rotating and unlocking, which could cause the switching node to become loose. This further enhances the reliability of the switch 100. When disassembly and maintenance are required, the operator only needs to release the locking between the second locking component 224 and the mounting bracket 221 to move the control component 223 and complete the unlocking and plugging / unplugging operation. The operation logic is clear, avoiding the risk of accidental loosening without increasing the complexity of disassembly and assembly operations, which helps to further improve the long-term stability of the switch 100.

[0091] In some embodiments of the present invention, such as Figure 5 , Figure 6 As shown, the disassembly and assembly mechanism 22 also includes an elastic element 225, which is connected between the second locking element 224 and the control element 223. As some embodiments of this application, the elastic element 225 can be constructed as a torsion spring, a coil spring, etc.

[0092] Mounting bracket 221 has a second locking engagement portion 2211. As some embodiments of this application, the second locking member 224 may have a hook, and the second locking engagement portion 2211 may have a locking hole. Alternatively, the second locking member 224 may have a locking hole, and the second locking engagement portion 2211 may have a hook. The second locking member 224 is configured to activate and compress the elastic member 225 when subjected to an external force reaching a preset value, so as to unlock from the second locking engagement portion 2211. The elastic member 225 is configured to drive the second locking member 224 to reset.

[0093] Specifically, the operator can press the second locking member 224. When the external force applied by the operator to the second locking member 224 reaches a preset value, the operator can press the second locking member 224 to make the second locking member 224 move and compress the elastic member 225. For example, the operator can press the second locking member 224 to make the second locking member 224 move or rotate and compress the elastic member 225 to unlock it from the second locking engagement part 2211. That is to say, the operator can use external force to make the second locking member 224 move to unlock it from the second locking engagement part 2211. At this time, the control member 223 is movable, and the operator can pull the control member 223 to unlock the corresponding switching node from the chassis 10. Furthermore, the elastic element 225 is configured to drive the second locking element 224 to reset. It is understood that when the external force applied to the second locking element 224 by the operator disappears, the elastic element 225 will rebound and drive the second locking element 224 to reset. If the control element 223 is in the locked position with the chassis 10 at this time, the reset second locking element 224 will lock into the second locking engagement part 2211.

[0094] With this configuration, under normal conditions, the elastic element 225 drives the second locking element 224 to remain in a reset and locked state by its own elastic force, so that the second locking element 224 is stably locked with the second locking engagement part 2211. This effectively reduces the risk of the control element 223 being misplaced and effectively avoids the risk of the control element 223 shifting due to factors such as vibration during operation of the switch 100 and accidental scraping. In addition, it can effectively prevent the problem of the switching node becoming loose due to the accidental rotation and unlocking of the first locking element 222, and further enhance the reliability of the switch 100. When disassembly and maintenance are required, only an external force exceeding the preset value needs to be applied to the second locking element 224 to compress the elastic element 225 and make the second locking element 224 disengage from the second locking engagement part 2211 to complete the unlocking. After the external force is removed, the elastic element 225 can automatically drive the second locking element 224 to spring back and reset, and lock with the second locking engagement part 2211 again without manual reset. The operation is simple and labor-saving, and it takes into account both the reliability of preventing accidental loosening and the convenience of daily operation and maintenance disassembly and assembly.

[0095] The computer system according to the present invention includes: a switch 100 and multiple servers, wherein the switch 100 is the aforementioned switch 100, and the multiple servers are all connected to the switch 100. The switch 100 of this application has a reasonable layout, which can significantly improve the support density of the switch 100. A single or a small number of switches 100 can meet the usage requirements, eliminating the need for a large number of interconnected devices. This helps to reduce power consumption and latency, and can also reduce the amount of fiber optic cable used, resulting in lower costs. Moreover, it occupies little space and is relatively convenient to deploy and maintain. In addition, any first switching node 20 is electrically connected to multiple second switching nodes 30, which can form a multi-path non-blocking forwarding path with better performance.

The descriptions of the embodiments above are merely for the purpose of helping to understand the method and core ideas of this application. It should be noted that those skilled in the art can make various improvements and modifications to this application without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this application.
