Detailed implementation manners

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts fall within the protection scope of the present application.

[0036] For the convenience of understanding, the following will explain some contents related to the embodiments of the present application: Traditional network architectures have some inherent defects: 1. Large transmission delay: Due to the existence of multi-layer switches, data transmission needs to pass through multiple intermediate nodes, which leads to the complexity of network transmission paths and increased transmission delay. Especially in large-scale data centers, this delay problem is more prominent, affecting the overall network performance.

[0037] 2. Multiple network layers: Traditional network architecture often requires multiple layers of switching equipment for traffic scheduling and management. As the scale of data centers expands, the number of network layers also increases, making equipment deployment and maintenance more complicated and increasing management difficulty.

[0038] 3. High equipment cost: Since a large number of switching devices need to be deployed, network cabling becomes more complicated, which invisibly increases the cost of network construction and maintenance.

[0039] 4. Hash polarization problem: Traditional data center switching equipment often uses a traffic distribution mechanism based on a hash algorithm. This mechanism can easily cause some links to be overloaded during peak traffic hours, while other links are idle, resulting in uneven traffic distribution and affecting the overall network performance.

[0040] There are also some solutions in the related technology, such as using higher performance switches or using new traffic scheduling algorithms. However, the effects of these solutions are still limited, and it is difficult to completely solve the problems of large transmission delay, multiple network levels, high cost and hash polarization. In the embodiments of the present application, a data transmission method, related equipment, optical network transmission system, medium and product are proposed to solve the problem that the related network transmission path is relatively complex and the data transmission delay is large.

[0041] See also Figure 1 , Figure 1 is a schematic diagram of the architecture of an optical network transmission system provided in an embodiment of the present application, such as Figure 1 As shown, the optical network transmission system includes multiple server groups, multiple OTN optical layer devices, multiple OTN electrical layer devices and optical interconnection devices, the optical interconnection devices are connected to the multiple OTN optical layer devices, the multiple OTN optical layer devices and the multiple OTN electrical layer devices are respectively deployed in multiple server groups, each of the multiple server groups includes multiple servers, and the multiple servers of each server group are respectively connected to the OTN electrical layer devices in the same server group, and the OTN optical layer devices in the same server group are connected to the OTN electrical layer devices. The data transmission method provided in the embodiment of the present application can be applied to multiple OTN optical layer devices, multiple OTN electrical layer devices and optical interconnection devices in the optical network transmission system.

[0042] See also Figure 2 , Figure 2It is one of the flowcharts of a data transmission method provided by an embodiment of the present application, which is applied to an optical interconnection device. The optical interconnection device is connected to multiple OTN optical layer devices, and the multiple OTN optical layer devices are respectively deployed in multiple server groups, such as Figure 2 shown. The method includes the following steps: Step 101: Receive a first optical signal sent by a first OTN optical layer device. Here, the first OTN optical layer device is an OTN optical layer device deployed in a first server group among the multiple OTN optical layer devices. The first server group is any one of the multiple server groups. The first optical signal is obtained by the first OTN optical layer device performing wavelength scheduling and multiplexing processing on at least one optical signal sent by a first OTN electrical layer device. The first OTN electrical layer device is deployed in the first server group and is connected to the first OTN optical layer device. The at least one optical signal is obtained by the first OTN electrical layer device converting the first transmission data of at least one server in the first server group.

[0043] In this step, the above optical interconnection device can be a device for multiplexing, routing, and distributing optical signals, with physical optical path switching, wavelength selection, and management functions, focusing on short-distance and high-efficiency optical transmission within a data center.

[0044] The above optical transport network (OTN) optical layer device can be deployed inside each server group to perform wavelength scheduling and management on optical signals within the server group. The OTN optical layer device is connected to the optical interconnection device. Since it is limited to short-distance transmission, functions such as amplification and dispersion compensation can be removed from the OTN optical layer device.

[0045] The above OTN electrical layer device can be deployed inside each server group for data transmission between servers within the same server group. The OTN electrical layer device is responsible for processing and cross-transmitting service data within the server group to realize communication between servers.

[0046] The above server group can be a cluster composed of multiple physical or virtual servers.

[0047] The above wavelength adjustment can be to allocate specific optical wavelengths to data from different sources for multiplexed transmission in an optical fiber. For example, if server A and server B need to send data to another group of servers, the first OTN optical layer device can allocate wavelengths of 1550 nm and 1560 nm to them respectively.

[0048] The above multiplexing process can be to combine optical signals of different wavelengths into a single composite optical signal for transmission. For example, the first OTN optical layer device can combine multiple optical signals such as 1550 nm and 1560 nm into a mixed light beam and transmit it to the optical interconnection device.

[0049] It can be understood that one OTN optical layer device and one OTN electrical layer device can be deployed in each server group, and the OTN optical layer device and the OTN electrical layer device in each server group are connected.

[0050] Step 102: Determine a target server group corresponding to the server group identification information carried in the first optical signal, where the target server group is any one of the multiple server groups.

[0051] In this step, the above server group identification information can be used to indicate the destination of the received data, that is, the target server group, and specifically can be metadata attached to the optical signal header or a specific field.

[0052] Step 103: Send the first optical signal to a second OTN optical layer device, where the second OTN optical layer device is the OTN optical layer device deployed in the target server group among the multiple OTN optical layer devices.

[0053] It can be understood that after the optical interconnection device sends the first optical signal to the second OTN optical layer device, the second OTN optical layer device can send the first optical signal to the OTN electrical layer device of the target server group, and the OTN electrical layer device of the target server group is responsible for restoring the data and sending it to the target server.

[0054] In the embodiment of the present application, the above data transmission method is applied to an optical interconnection device. By receiving the first optical signal sent by the first OTN optical layer device, determining the target server group corresponding to the server group identification information carried in the first optical signal, and sending the first optical signal to the second OTN optical layer device, it is possible to avoid using a multi-layer Ethernet switch during data transmission, thereby reducing the intermediate nodes in data transmission, simplifying the data transmission path, reducing the data transmission delay, and solving the Hash polarization problem by performing data transmission through a fixed-path optical channel. At the same time, the optical interconnection device can replace the traditional multi-layer switching architecture, greatly simplifying the network hierarchy and reducing the management difficulty and operation and maintenance cost.

[0055] Optionally, the sending the first optical signal to the second OTN optical layer device includes: Determining a target port based on a preset routing rule, where the preset routing rule is used to indicate the correspondence between the second OTN optical layer device and the target port; Send the first optical signal to the second OTN optical layer device based on the target port.

[0056] Specifically, the above preset routing rules can be static or dynamic rule tables pre-configured in the optical interconnection device, mapping different server group identifiers to corresponding physical or logical ports.

[0057] Furthermore, the optical interconnection device further includes a signal monitoring and fault handling function, which can monitor the status of each optical channel in real time, detect whether there are abnormal signals or faults. When the optical interconnection device detects an abnormal signal or fault, the optical interconnection device will automatically switch to the backup optical path to ensure the continuity and reliability of data transmission.

[0058] In this embodiment, by determining the target port based on the preset routing rules, the preset routing rules are used to indicate the correspondence between the second OTN optical layer device and the target port; sending the first optical signal to the second OTN optical layer device based on the target port, enabling the optical signal to flexibly switch to the target port inside the optical interconnection device, completing the optical path switching, realizing the interconnection between different server groups, and transmitting traffic through the optical channels with fixed paths, thereby avoiding the problem of uneven network traffic load, that is, solving the Hash polarization problem, and thus improving the network performance.

[0059] Optionally, before sending the first optical signal to the second OTN optical layer device, the method further includes: Adjust the wavelength of the first optical signal based on the transmission distance between the first server group and the target server group.

[0060] Specifically, the above adjustment of the wavelength of the first optical signal can be dynamically selecting or modifying the carrier wavelength of the optical signal according to the transmission distance characteristics.

[0061] It should be noted that when deploying the optical interconnection device, the optical interconnection device can be initialized, including the configuration of the physical optical path, the setting of the wavelength scheduling rules, etc. The optical interconnection device ensures that the optical signal transmission paths between server groups are reasonably configured in the initialization stage through the preset logic.

[0062] In this embodiment, adjusting the wavelength of the first optical signal based on the transmission distance between the first server group and the target server group enables dynamic adjustment of the wavelength allocation according to the transmission requirements between different server groups, and improves the utilization efficiency of optical fiber resources through wavelength management, thereby improving the stability and flexibility of communication between each server group.

[0063] Optionally, the optical interconnection device is not provided with a transmission component for optically amplifying and dispersion compensating an optical signal.
