[0111] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0112] For ease of understanding, some of the contents involved in the embodiments of this application are described below:

[0113] Traditional network architecture has some inherent defects:

[0114] 1. High transmission delay: Due to the presence of multi-layer switches, data transmission must pass through multiple intermediate nodes, which leads to the complexity of network transmission paths and increased transmission delay. This delay problem is particularly prominent in large-scale data centers, affecting overall network performance.

[0115] 2. Multiple network layers: Traditional network architectures often require multiple layers of switching equipment for traffic scheduling and management. As data centers expand, the number of network layers increases, making equipment deployment and maintenance more complex and increasing management difficulty.

[0116] 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.

[0117] 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 periods, while other links remain idle, resulting in uneven traffic distribution and affecting overall network performance.

[0118] There are some solutions in the related art, such as using higher-performance switches or new traffic scheduling algorithms. However, the effectiveness of these solutions is still limited, and it is difficult to completely solve the problems of large transmission delays, multiple network layers, high costs, and hash polarization. In the embodiments of this application, a data transmission method, related equipment, optical network transmission system, medium, and products are proposed to solve the problems of complex network transmission paths and large data transmission delays.

[0119] See also Figure 1 , Figure 1 This is a schematic diagram of the architecture of an optical network transmission system provided by an embodiment of the present application. Figure 1As 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. The multiple servers in each server group are respectively connected to the OTN electrical layer devices in the same server group. 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 the multiple OTN optical layer devices, multiple OTN electrical layer devices, and optical interconnection devices in the optical network transmission system.

[0120] See also Figure 2 , Figure 2 This is one of the flow charts of a data transmission method provided in an embodiment of the present application, which is applied to an optical interconnection device, wherein 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 As shown, the method includes the following steps:

[0121] Step 101: Receive a first optical signal sent by a first OTN optical layer device, wherein 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 wavelength combining 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, the first OTN electrical layer device is connected to the first OTN optical layer device, and the at least one optical signal is obtained by the first OTN electrical layer device converting first transmission data of at least one server in the first server group.

[0122] In this step, the optical interconnection equipment can be a device used for multiplexing, routing and splitting optical signals, with physical optical path switching, wavelength selection and management functions, and focuses on short-distance and efficient optical transmission within the data center.

[0123] The above-mentioned Optical Transport Network (OTN) optical layer equipment can be deployed inside each server group to perform wavelength scheduling and management of the optical signals within the server group. The OTN optical layer equipment is connected to the optical interconnection equipment. Since it is limited to short-distance transmission, functions such as amplification and dispersion compensation can be removed from the OTN optical layer equipment.

[0124] The above-mentioned OTN electrical layer equipment can be deployed inside each server group for data transmission between servers in the same server group. The OTN electrical layer equipment is responsible for processing and cross-transmitting business data within the server group to realize communication between servers.

[0125] The server group may be a cluster consisting of multiple physical or virtual servers.

[0126] The above wavelength adjustment can be to assign specific optical wavelengths to data from different sources for multiplexing and transmission in the optical fiber. For example, server A and server B need to send data to another group of servers, and the first OTN optical layer device can assign them 1550nm and 1560nm wavelengths respectively.

[0127] The above-mentioned wavelength combining process can 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 1550nm and 1560nm into a mixed light beam and transmit it to the optical interconnection device.

[0128] It is understandable that one OTN optical layer device and one OTN electrical layer device may be deployed in each server group, wherein the OTN optical layer device and the OTN electrical layer device in each server group are connected.

[0129] Step 102: Determine a target server group corresponding to the server group identification information according 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.

[0130] In this step, the server group identification information may be used to indicate the destination of the received data, ie, the target server group, and may specifically be metadata attached to the optical signal header or a specific field.

[0131] Step 103: Send the first optical signal to a second OTN optical layer device, where the second OTN optical layer device is an OTN optical layer device deployed in the target server group among the multiple OTN optical layer devices.

[0132] It can be understood that after the above-mentioned 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.

[0133] In an embodiment of the present application, the above-mentioned data transmission method is applied to an optical interconnection device. By receiving a first optical signal sent by a first OTN optical layer device, the target server group corresponding to the server group identification information is determined based on the server group identification information carried in the first optical signal, and the first optical signal is sent to a second OTN optical layer device. This eliminates the need to use a multi-layer Ethernet switch during data transmission, thereby reducing intermediate nodes for data transmission and simplifying the data transmission path, thereby reducing data transmission latency. Furthermore, data transmission through an optical channel with a fixed path can solve the hash polarization problem. At the same time, the optical interconnection device can replace the traditional multi-layer switching architecture, greatly simplifying the network hierarchy and reducing management difficulty and operation and maintenance costs.

[0134] Optionally, the sending the first optical signal to the second OTN optical layer device includes:

[0135] Determine a target port based on a preset routing rule, where the preset routing rule is used to indicate a correspondence between the second OTN optical layer device and the target port;
