Description

Technical Field

[0001] The present invention relates to the field of computer technology, and in particular to a device numbering method, apparatus, and storage medium. Background Art

[0002] Traditional distributed disaggregate chassis (DDC) network equipment systems include a network cloud controller (NCC), a network cloud fabric (NCF), and a network cloud packet forwarder (NCP). In a DDC system, the NCC controls communication between the NCF and NCP. This centralized system architecture carries the risk of system failure due to NCC disconnection.

[0003] Based on the traditional DDC system architecture, a decentralized DDC system has evolved. This decentralized DDC system eliminates the NCC, retaining the NCP and NCF. NCPs synchronize information through the NCF without the involvement of the NCC, eliminating the issue of system failures caused by NCC loss. However, the decentralized DDC system architecture has a large number of NCP / NCF devices, and without the NCC automatically assigning device numbers, the process of determining a device number is cumbersome. Summary of the Invention

The DDC system includes a first device and at least one second device. Taking the first device as an example, the method specifically comprises: the first device sends M first messages to each of at least one second device. Each of the M ports in each second device is connected to M ports in the first device. The M first messages corresponding to the i-th second device are used to request the numbers of the M ports in the i-th second device connected to the first device. The M first messages correspond one-to-one with the M ports, where M is a positive integer greater than or equal to 1. The first device is an NCF and the second device is an NCP, or the first device is an NCP and the second device is an NCF. The first device receives M second messages from each of the at least one second device. The M second messages corresponding to the i-th second device include the numbers of the M ports in the i-th second device. The M second messages correspond one-to-one with the M ports. All second messages received by the first device from the at least one second device correspond to a total of N port numbers, where N is a positive integer greater than or equal to 1. If the N port numbers are the same, the first device determines that the number of the first device is any one of the N port numbers.

The M first messages correspond one-to-one with the M ports, where M is a positive integer greater than or equal to 1. The first device is an NCF and the second device is an NCP, or the first device is an NCP and the second device is an NCF.

All second messages received by the first device from at least one second device correspond to a total of N port numbers, where N is a positive integer greater than or equal to 1. The determining module is configured to determine that the number of the first device is any one of the N port numbers if the N port numbers are the same.

[0025] This application relates to a device numbering method, which can be used to number devices in a decentralized DDC system. Since the decentralized DDC system is evolved from the traditional DDC system, a brief introduction to the DDC system is first given.

[0026] like Figure 1 The DDC system is a separate rack network device system developed based on an application-specific integrated circuit (ASIC) chip. The DDC system separates the NCC, NCF, and NCP, making the NCP, NCF, and NCC physically independent devices, interconnected by cables to form a logical rack switch. The NCP is equivalent to a line card in a rack system, the NCF is equivalent to a switching network board in a rack system, and the NCC is equivalent to a management board in a rack system. The NCC can be connected to the NCP and / or NCF via a management network device.

[0027] The NCC can control the NCP and / or NCF by managing network devices. For example, the NCC can aggregate global table entry information and distribute it to the NCP and / or NCF through the management network devices. Global table entry information includes media access control layer (MAC) information, address resolution protocol (ARP) messages, and routing information. Accordingly, the NCP and / or NCF can report global table entry information to the NCC through the management network devices.

[0028] In this system, information synchronization between NCPs is performed through the NCC. For example, an NCP must report global table entries, device information, and port numbers to the NCC via the management network device. The NCC then forwards this information to the other NCP using the device information and port numbers provided by the NCP.

[0029] Because NCPs, NCFs, and NCCs are physically independent, the number of NCPs, NCFs, and NCCs in the system is not limited by the number of slots in the switch rack and can be flexibly expanded. For example, the number of NCPs in a DDC system can be increased to 100 or even more. However, as the number of NCPs in a DDC system increases, the risk of failure in the DDC system gradually increases. For example, when an NCC manages a large number of NCPs, it is prone to failures on the network nodes connected to the NCPs and / or NCFs, causing the NCC to lose connection with the NCPs and / or NCFs. Once the NCC loses connection with the NCPs and / or NCFs, the DDC system will lose control, affecting the normal operation of the NCPs and / or NCFs in the network.

[0030] like Figure 2 As shown in the figure, based on the shortcomings of the DDC system, a decentralized DDC system architecture is proposed.

[0031] This decentralized DDC system eliminates the NCC and management network devices, retaining the NCP and NCF. NCPs and NCFs are fully connected: one NCP connects to all NCFs in the system, and similarly, one NCF connects to all NCPs in the system. Global table entry information, previously aggregated and distributed by the NCC to individual devices, is now directly processed by the NCP for distributed processing. This allows the NCP in this system to have control (also known as the control plane) and management (also known as the management plane) functions similar to those of the NCC, allowing the NCP to communicate with other devices independently of the NCC.

[0032] Considering that the NCC, NCP, and NCF devices in the DDC system are designed based on ASIC chips, the ASIC chips support adding a header layer to messages forwarded between chips, forming a fabric message. The ASIC chips configure registers to designate the chip interconnect ports as fabric ports, which are used to forward fabric messages encapsulated with the header. In other words, the ASIC-based NCP and NCF can send fabric messages through the fabric ports. Specifically, to minimize bandwidth usage, the ASIC chip header occupies an 8-byte preamble and a 4-byte interpacket gap (IPG).

[0033] like Figure 3 As shown in the figure, the NCP and NCF are connected through fabric ports, and the NCF is connected to the NCP through fabric ports. This NCP-NCF-NCP fabric channel forms a fabric channel. When an NCP needs to synchronize information with another NCP, it sends global table entry information, device information, and port numbers to the NCF connected to it through the NCP-NCF-NCP fabric channel. The NCF then forwards the information to the other NCP, ultimately achieving information synchronization.

[0034] However, this decentralized DDC system has a large number of devices, and without an NCC to number the NCPs and / or NCFs, determining device numbers is a complex process. Furthermore, when new NCPs and / or NCFs are added to the system, device numbers must be manually assigned to avoid conflicts with other devices. This makes expansion of the system difficult.

[0035] In view of this, embodiments of the present application provide a device numbering method. This method allows devices in the system to automatically determine their device numbers based on their connections to other devices, making it more convenient. Furthermore, there's no need to manually configure device numbers for newly added devices, making the system easier to expand.

[0036] See Figure 4 , shows that based on Figure 3Flowchart of the device numbering method of the system architecture shown. The method can be applied to an electronic device with processing capabilities, which can be an NCP, NCF, etc. in the above-mentioned decentralized DDC system. Of course, the electronic device can also be other types of devices, such as a tablet computer (PAD), a personal computer (PC), etc., and the types of electronic devices in the embodiments of the present invention are not limited to this. In the subsequent introduction, considering that the electronic device establishes a connection with other electronic devices in the system, in order to distinguish the electronic device for which the device number needs to be determined from the other electronic devices connected to it, the electronic device for which the device number needs to be determined is referred to as the first device, and the other electronic devices connected to the first device are referred to as the second device.

[0037] S401. The first device sends M first messages to each of the at least one second device, wherein the M ports in each second device are connected to the M ports in the first device, and the M first messages corresponding to the i-th second device are used to request the numbers of the M ports in the i-th second device connected to the first device. The M first messages correspond one-to-one to the M ports, and M is a positive integer greater than or equal to 1; the first device is an NCF, and the second device is an NCP, or the first device is an NCP and the second device is an NCF.

[0038] The connection between multiple devices in the system is more complicated. One device usually needs to establish connections with multiple other devices, such as Figure 5 As shown, the connection between multiple devices in the decentralized DDC system is shown. Usually, a full connection is established between the NCP and the NCF in the system, that is, an NCP in the system needs to establish a connection with all NCFs, and similarly, an NCF needs to establish a connection with all NCPs. A connection is established between an NCP and at least one NCF. When it is necessary to determine the device number of the NCP, the NCP can be regarded as the first device, and the at least one NCF connected to it can be regarded as the second device, that is, corresponding to at least one second device. Alternatively, a connection is established between an NCF and at least one NCP. When it is necessary to determine the device number of the NCF, the NCF can be regarded as the first device, and the at least one NCP connected to it can be regarded as the second device. For the convenience of description, the process of determining the NCP device number will be explained below using NCP as the first device as an example. When the first device is NCF, the process of determining the device number is similar and will not be repeated.

[0039] Typically, the first device and the second device are provided with multiple ports (for example, multiple fabric ports), and the M ports in the first device can establish connections with the M ports of each second device to achieve networking of multiple first devices and multiple second devices. Here, M can be considered as the number of port connections between the first device and the second device, and M is a positive integer greater than or equal to 1. Since the port connection has a one-to-one correspondence, and the number of ports of each first device and second device is limited, different numbers of port connections M between the first device and the second device can be set according to different connection strategies. For example, in order to achieve the maximum scale networking of the system, one port connection between the first device and the second device can be set, that is, M is 1, so that the system can accommodate as many devices as possible. The maximum number of first devices in the system is the number of ports set on the second device, and the maximum number of second devices is the number of ports set on the first device. For another example, in order to achieve better bandwidth utilization, the first device can be set to be connected to at least two ports of each second device, that is, M is greater than 1. In this way, the system can accommodate a relatively small number of first devices, but the first devices are connected to more ports of the second devices. Therefore, each first device can occupy more resources of the second device. When the ports of the second device are not fully occupied, the utilization of the idle bandwidth of the second device can be improved.

[0040] Based on this networking mode of the first device and the second device, it is necessary to number the devices in the system to prevent conflicts between devices. Figure 5 , multiple NCPs can be numbered NCP1, NCP2, NCP3, NCP4..., and multiple NCFs can be numbered NCF1, NCF2, NCF3, NCF4.... When a first device (for example, NCP1) communicates with an NCP in the system (for example, NCP2) through a fabric channel, NCP1 reports information to the NCF. The information reported by NCP1 includes the number of NCP1's communication partner, that is, the number of NCP2. The NCF can forward the information reported by NCP1 to NCP2 based on the number of NCP2 in the information reported by NCP1. Correspondingly, NCP2 needs to feedback information to NCP1 based on the number of NCP1. Therefore, each device in the system should have its own independent number, which is used to uniquely identify the device to prevent communication conflicts between devices in the system.

[0041] Similarly, to prevent conflicts between ports during communication between devices, which could lead to information transmission errors, the ports on each device can be numbered. For example, the ports of NCP1 could be numbered 1_1, 1_2, 1_3, 1_4, etc., and the ports of NCP2 could be numbered 2_1, 2_2, 2_3, 2_4, etc. After the ports of each device are numbered, the devices can communicate through fixed ports.

[0042] Therefore, each device in the system should have a device number that is unique to other devices, and only devices assigned a device number can be used in the system. However, in some cases, a device number may not exist. For example, a first device may not have a device number when it is newly added to the system. Another example is when the configuration information related to the device number is manually deleted, the first device's device number may no longer exist. In related technologies, when a device number does not exist, it is necessary to manually assign a device number to the device.

[0043] In an embodiment of the present application, considering that the M ports in the first device are connected to the M ports of each second device, the first device can send a request to at least one connected second device to request the numbers of the M ports in the i-th second device that are connected to the first device. Since the ports on the second devices are usually occupied in sequence, that is, when each first device occupies a port on the second device, it occupies the port immediately adjacent to the previously occupied port. Therefore, the first device can determine the occupancy status of the ports on the second device based on the M port numbers requested in the first message, and further determine the number of the first device in the system based on the occupancy status of the ports on the second device.

[0044] The first device edits a first message and requests the numbers of the M ports connected to the first device in the i-th second device through the first message. For the number of each port of the second device, the first device requests the number of the port by sending a first message, that is, for each second device, the first device sends M first messages, and the M first messages correspond one-to-one to the M ports. The first device can send M first messages to each second device in at least one second device connected to it. Since the first device and the second device are connected through a fabric port, the first message sent by the first device can be a fabric message. There are many ways for the first device to send the first message. For example, it can be detected through the serdes connection detection method provided by the ASIC chip, or a detection protocol similar to lldp. Before sending the first message, in order to prevent conflicts with other devices, the first device can set a default device number that does not conflict with other devices, such as number 0.

[0045] S402: The first device receives M second messages from each of the at least one second device. All second messages received by the first device from the at least one second device correspond to a total of N port numbers. If the N port numbers are the same, the first device determines that the number of the first device is any one of the N port numbers. The M second messages corresponding to the i-th second device include the numbers of the M ports. The M second messages correspond one-to-one to the M ports, and N is a positive integer greater than or equal to 1.

[0046] The first device sends M first messages to each second device. Accordingly, for each first message, the i-th second device sends back a second message to the first device. The first device can then receive M second messages sent by each of the at least one second device, with the M second messages corresponding one-to-one to the M ports. The M first messages sent by the first device request the numbers of the M ports connected to the first device on the i-th second device. The second message, which carries the port number of the i-th second device, serves as a response to the first message. The M second messages include the port numbers of the M second devices. A total of N port numbers correspond to all second messages received by the first device from at least one second device, meaning that at least one second device corresponds to N port numbers. The first device can determine its own device number based on these N port numbers. When determining its own device number based on the N port numbers, the first device can categorize the port number determination into various situations, depending on the number M of port connections between the first device and each second device.

[0047] Case 1: The first device is connected to one port of each second device, that is, M is 1. In this case, the first device only requests one port number of the i-th second device, and the number of port numbers N in the second message received by the first device is the same as the number of second devices. The first device can compare whether these N port numbers are consistent. For example, it can be determined based on the comparison whether these N port numbers are all m at the same time. If these N port numbers are all m at the same time, it can be considered that the first device is the m-th device occupying the port of the second device. Before this, there is already an m-1-th device occupying the port of each second device in sequence. And when each device occupies the port of the second device, it occupies the port immediately after the last occupied port. In this way, the N port numbers obtained by the first device are all m at the same time. Therefore, the first device can determine that the device number of the first device is any port number m among the N port numbers.

[0048] Of course, the N port numbers obtained by the first device may be inconsistent. This is because the first device may have made a connection error when connecting to a port of the second device and may not have occupied the ports of the second device in the correct order, resulting in an inconsistency in the N port numbers obtained by the first device. In this case, the first device may indicate a connection error. Specifically, the first device may output a prompt indicating that a connection error has occurred between the first device and at least one second device.

[0049] In this case, it can be assumed that a few ports have connection errors, while the majority of ports are connected normally. In this case, the device number of the first device can still be determined. The first device can determine the device number of the first device based on the port number that appears the most times among the N port numbers. For example, if the port number that appears the most times is m, then m can be determined as the device number of the first device.

[0050] After the device number of the first device is determined, the determined device number is saved in the configuration information of the first device. After the device number is saved, it is necessary to restart the device or restart the process to reinitialize all services that rely on the device number. After the first device is restarted again, the first device uses the device number included in the configuration information. This allows the first device to use this device number to conduct services when communicating with other devices in the system.

[0051] Case 2: The first device is connected to at least two ports of the second device, that is, M is greater than 1. In this case, the number N of port numbers in the second message received by the first device is M times the number of second devices.

[0052] Since the number of port connections between the first device and each second device is M, and the number of port connections between other devices and each second device is also M, when each first device is connected to a port of a second device, it occupies the port immediately after the last occupied port. Even if there are many differences between the N port numbers obtained by the first device, for example, when M is 3, the N port numbers obtained by the first device include 3, 4, 5, 3, 4, 5, 3, 4, 5, 3, 4, 5..., the device number of the first device can also be determined.

[0053] The first device determines the device number of the first device as the ratio of any one of the N port numbers to M, rounded up. For example, when M is 3 and the N port numbers obtained by the first device include 3, 4, 5, 3, 4, 5, 3, 4, 5, 3, 4, 5, ..., the ratio of any one of the N port numbers to the number of port connections M is rounded up to 2. That is, in this example, the device number of the first device is 2.

[0054] Similarly, after the device number of the first device is determined, the determined device number is saved in the configuration information of the first device. After the device number is saved, it is necessary to restart the device or restart the process to reinitialize all services that rely on the device number so that the first device can use the device number to perform services when communicating with other devices in the system.

[0055] See Figure 6 Based on the same inventive concept, an embodiment of the present application also provides a device numbering device 600. The device 600 includes: a sending module 601, a receiving module 602 and a determining module 603. The sending module 601 is used to send M first messages to each of the second devices in at least one second device. The M ports in each second device are connected to the M ports in the first device, and the M first messages corresponding to the i-th second device are used to request the numbering of the M ports in the i-th second device connected to the first device. The M first messages correspond one-to-one to the M ports, and M is a positive integer greater than or equal to 1. The first device is an NCF, the second device is an NCP, or the first device is an NCP and the second device is an NCF. The receiving module 602 is configured to receive M second messages from each of at least one second device, where the M second messages corresponding to the i-th second device include the numbers of the M ports in the i-th second device. The M second messages correspond one-to-one to the M ports. All second messages received by the first device from the at least one second device correspond to a total of N port numbers, where N is a positive integer greater than or equal to 1. The determining module 603 is configured to determine that the number of the first device is any one of the N port numbers if the N port numbers are the same.

[0056] Optionally, the determining module 603 is further configured to: determine the port number that appears the most times among the N port numbers as the number of the first device.

[0058] Optionally, the determining module 603 is further configured to determine that the number of the first device is a ratio of any one of the N port numbers to M, rounded up.

[0059] Optionally, the determination module 603 is further configured to: store the number of the first device in the configuration information, where the number of the first device in the configuration information is the number used by the first device after the next restart.
