[0025] In order to make the purpose, technical solution and advantages of the present disclosure more obvious, the exemplary embodiments according to the present disclosure will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments of the present disclosure, and it should be understood that the present disclosure is not limited to the exemplary embodiments described here.

[0026] Figure 1 It is a flowchart illustrating a data processing method according to an embodiment of the present disclosure.

[0027] like Figure 1 As shown, the data processing method according to the embodiment of the present disclosure is performed by a network device, which refers to a device that performs data processing tasks in a network environment and integrates field programmable gate array (FPGA) technology to support efficient and flexible data forwarding. The network device may be a base station.

[0028] In step S101, based on the application scenario, the corresponding relationship between multiple forwarding nodes included in the field programmable gate array FPGA is determined.

[0029] In the embodiments of the present disclosure, the application scenario includes information such as the network environment in which the network device is located, different signal coverage ranges, business requirements, and performance requirements. Through comprehensive analysis of this information, the specific functions and performance indicators that the network device needs to implement can be clarified. According to the application scenario, the connection relationship between the multiple forwarding nodes included in the FPGA can be established. These connection relationships determine the transmission path and timing of the data inside the FPGA. Exemplarily, according to the complexity of the network environment, the connection relationship of the forwarding node can be adjusted to optimize the data transmission path and reduce congestion and delay; according to the signal coverage requirements, the connection relationship of the forwarding node can be adjusted to increase signal enhancement to ensure that the signal can cover the target area and reduce blind spots; according to business needs, the connection relationship of the forwarding node can be adjusted to ensure business quality; according to network performance indicators, the corresponding relationship of the forwarding node can be dynamically adjusted to adapt to changes in the network environment and changes in business needs.

[0030] Specifically, a forwarding node may refer to a functional module that can implement data forwarding. A forwarding node may also correspond to a functional interface of a network device. Here, an interface generally refers to a physical or logical connection point for exchanging data between different functional modules or devices.

[0031] In step S102, multiple forwarding nodes are polled.

[0032] In an embodiment of the present disclosure, the network device starts polling multiple forwarding nodes in a predetermined order. In each polling, the network device checks the status of the current node, including whether there is readable data.

[0033] In step S103, a read operation is performed on a readable forwarding node, and based on the corresponding relationship, the read data is forwarded to a target forwarding node, where the readable forwarding node and the target forwarding node are nodes among a plurality of forwarding nodes.

[0034] In the embodiments of the present disclosure, a readable forwarding node refers to a forwarding node with readable data. When the network device detects that the current node (i.e., the readable forwarding node) has readable data, the data is read from the forwarding node, and the read data is forwarded to the target node connected to the readable forwarding node according to the connection relationship between the multiple forwarding nodes. Here, the readable forwarding node and the target forwarding node are both nodes in the multiple forwarding nodes inside the FPGA.

[0035] In summary, according to the technical solution provided by the embodiment of the present disclosure, the present disclosure dynamically adjusts the correspondence between multiple forwarding nodes through application scenarios, and utilizes polling forwarding nodes to achieve efficient and flexible forwarding of data in network devices. When a forwarding node in the network device is damaged or abnormal, since the FPGA contains multiple forwarding nodes, the correspondence between the multiple forwarding nodes can be dynamically adjusted. Therefore, by reconfiguring the correspondence between these nodes, the damaged forwarding node can be bypassed and the data can be forwarded to other available forwarding nodes, which can reduce the need for equipment replacement due to damage to the forwarding node and improve the stability and reliability of the system.

[0036] Figure 2 FIG. 4 is a schematic diagram illustrating the structure of an FPGA according to an embodiment of the present disclosure.

[0037] like Figure 2 As shown, according to the FPGA of the embodiment of the present disclosure, FPGA200 includes multiple forwarding nodes, and the multiple forwarding nodes include at least: a cell forwarding node 201, a built-in forwarding node 202, an external forwarding node 203 and a cascade forwarding node 204.

[0038] Among them, the cell forwarding node 201 is used to carry data corresponding to the covered cell, the built-in forwarding node 202 is used to forward the data corresponding to the cell forwarding node to other network devices or terminals, the external forwarding node 203 is used to forward the data corresponding to the cell forwarding node to other network device connections or terminals, and the cascade forwarding node 204 realizes the cascading of network devices with other network devices.

[0039] Specifically, the cell forwarding node 201 is responsible for collecting, storing and preliminarily processing data from the cell covered by the network device. Here, the cell forwarding node 201 is specifically responsible for processing data of a single cell. If the network device covers multiple cells, then the FPGA will include multiple cell forwarding nodes 201.

[0040] Preferably, there are two cell forwarding nodes 201, corresponding to the first cell and the second cell respectively.

[0041] The built-in forwarding node 202 is set inside the network device and is used to forward the data collected by the cell forwarding node 201 to other network devices or terminals outside the network device. For example, the built-in forwarding node 202 can be a functional module corresponding to the RRU interface of the remote radio unit.

[0042] The external forwarding node 203 can forward the data collected by the cell forwarding node 201 to other network devices or terminals outside the network device. The cascade forwarding node 204 can realize the cascade connection between the network device and other external network devices, allowing data to flow between different network layers or different network devices, thereby expanding the data transmission range.

[0043] In summary, according to the technical solution provided by the embodiment of the present disclosure, the FPGA architecture of the present disclosure integrates multiple forwarding nodes to build an efficient and flexible network data processing platform. This design not only improves the efficiency of network data transmission, but also enhances the reliability and scalability of the network, providing strong support for modern communications and Internet of Things applications.

[0044] Furthermore, the plurality of forwarding nodes further include a first forwarding node 205 and a second forwarding node 206 .

[0045] The first forwarding node 205 is used for communication connection with the core network, and the second forwarding node 206 is used for communication connection with the central processing unit CPU of the network device.

[0046] Specifically, the first forwarding node 205 serves as a bridge between the network device and the core network, and is responsible for receiving data packets from the core network and transmitting the processed data packets back to the core network.

[0047] Figure 3 It is a schematic diagram further illustrating the structure of the FPGA according to an embodiment of the present disclosure.

[0048] like Figure 3 As shown, according to the FPGA of an embodiment of the present disclosure, FPGA200 includes multiple forwarding nodes, and the multiple forwarding nodes include at least: a first forwarding node a, a cell forwarding node b, a cell forwarding node c, a second forwarding node d, a built-in forwarding node g, an external forwarding node f and a cascade forwarding node e.

[0049] Furthermore, based on the application scenario, the corresponding relationship between multiple forwarding nodes included in the field programmable gate array FPGA is determined, including:

[0050] When a cell is determined to be covered, the cell forwarding node corresponding to the cell is connected to the built-in forwarding node.

[0051] Specifically, when a cell needs to be covered, that is, in an application scenario of small-scale coverage, the forwarding node corresponding to the cell is connected to the built-in forwarding node.

[0052] For example, see Figure 3 When the network device covers a cell, the cell node b is connected to the built-in forwarding node g as an IQ data link. If it is necessary to implement multi-level cascading of the network device, further, the first forwarding node a is connected to the second forwarding node d, and the second forwarding node d is connected to the cascade forwarding node e.

[0053] Furthermore, based on the application scenario, the corresponding relationship between multiple forwarding nodes included in the field programmable gate array FPGA is determined, including:

[0054] When it is determined that the first cell and the second cell are covered, the cell forwarding node of the first cell is connected to the built-in forwarding node, and the cell forwarding node of the second cell is connected to the external forwarding node.

[0055] Specifically, when two cells need to be covered, namely the first cell and the second cell, the coverage needs to be expanded, the cell forwarding node of the first cell is connected to the built-in forwarding node, and the cell forwarding node of the second cell is connected to the external forwarding node.

[0056] For example, see Figure 3 When the network device covers the first cell and the second cell, the cell forwarding node b corresponding to the first cell can be connected to the built-in forwarding node g as the IQ data link of the first cell, and the cell forwarding node c corresponding to the second cell can be connected to the external forwarding node f as the IQ data link of cell 2. Furthermore, in order to realize the cascading of network devices, the first forwarding node a is connected to the second forwarding node d, and the second forwarding node d is connected to the cascade forwarding node e.

[0057] Furthermore, based on the application scenario, the corresponding relationship between multiple forwarding nodes of the network device is determined, including:

[0058] When determining to cover the first cell and the second cell, the cell forwarding node of the first cell is connected to the cascade forwarding node, and the cell forwarding node of the second cell is connected to the external forwarding node; wherein the cascade forwarding node is used to connect to other network devices or terminals.

[0059] Specifically, when it is necessary to cover two cells, namely the first cell and the second cell, and it is necessary to enhance the coverage quality of a specific area and the scalability of a large-scale network, the cell forwarding node of the first cell is connected to the cascade forwarding node, and the cell forwarding node of the second cell is connected to the external forwarding node; wherein the cascade forwarding node is used to connect to other network devices or terminals.

[0060] For example, see Figure 3 When the network device covers the first cell and the second cell, the cell forwarding node b corresponding to the first cell can be connected to the cascade forwarding node e as the IQ data link of the first cell, and the cell forwarding node c corresponding to the second cell can be connected to the external forwarding node f as the IQ data link of cell 2. Furthermore, the first forwarding node a is connected to the second forwarding node d. The first cell and the second cell are connected to the external optical port.

[0061] For other scenarios, you can modify the configuration online according to changes in requirements.

[0062] In summary, according to the technical solution provided by the embodiment of the present disclosure, the present disclosure quickly adjusts the connection mode of the forwarding node according to different application scenarios without hardware replacement or large-scale modification. Furthermore, through the design of cascaded forwarding nodes and external forwarding nodes, the network coverage can be easily expanded to meet the needs of networks of different scales.

[0063] Further, polling the plurality of forwarding nodes includes: based on a state machine, polling first-in-first-out queues FIFOs corresponding to the plurality of forwarding nodes respectively.

[0064] Furthermore, a read operation is performed on a readable forwarding node, including:

[0065] When the FIFO is in a non-empty state, the forwarding node corresponding to the FIFO is a readable forwarding node, and a read operation is performed on the readable forwarding node.

[0066] In one embodiment of the present disclosure, a queue forwarding module can be set up for each of the above-mentioned multiple forwarding nodes. The queue forwarding module uses a blockram+small FIFO method. The blockram is used as the main storage area to store complete data packets; and the FIFO is used as an auxiliary storage area to store descriptors pointing to these data packets (including the length of the data packet and the base address in the blockram). This design ensures efficient access to data and avoids unnecessary memory waste. For example, Figure 4 As shown in the figure, the schematic diagram of the queue forwarding module is to count the data received in each forwarding node. Here, the length of the data can be counted, and the base address can be recorded, and the length and base address can be written into the FIFO as descriptors. Each descriptor is processed in the polling read control module, and the data queue is transmitted to the 10G port.

[0067] Use the state machine to poll each forwarding node. Figure 5As shown in the figure, it is a flowchart of polling the forwarding node. The state machine is in the idle state by default, and then continuously polls the FIFO of the descriptor in the forwarding module of each team. When the FIFO is empty, it jumps back to idle. When it is not empty, it reads the descriptor of the FIFO. After obtaining the description information, it searches the corresponding RAM for the base address and length corresponding to the descriptor, and then reads the data in the forwarding module of the team. That is, data is read from the forwarding node. Continue to poll the forwarding node and repeat the above steps.

[0068] Furthermore, a switch enable can be made at the entrance of each queue forwarding module, so that the direction of the data path can be flexibly controlled by setting the switch enable.

[0069] Furthermore, the classification information and time information of the queue can be added to the descriptor, and the residence time of each queue can be accurately measured. On this basis, the queue can be filtered, modified, and other operations can be performed.

[0070] In summary, according to the technical solution provided by the present disclosure, the technical solution of the present disclosure can achieve the following technical effects.

[0071] 1. When the cascade forwarding node is damaged and the external forwarding node on the FPGA is not in use, the external forwarding node can be used as the cascade forwarding node.

[0072] 2. When the cascade function is not needed, cascade forwarding nodes and external forwarding nodes can be used to realize the function of optical fiber extending two cells (such as the first cell and the second cell).

[0073] 3. It can also be configured into two cells and support multi-level cascade products (i.e. one cell is connected to the built-in forwarding node, and one cell is connected to the external forwarding node. The cascade forwarding nodes realize the cascade function, and then realize multi-level cascade).

The present disclosure dynamically adjusts the corresponding relationship of multiple forwarding nodes through application scenarios, and uses polling forwarding nodes to achieve efficient and flexible forwarding of data in network devices. When a forwarding node in the network device is damaged or abnormal, since the FPGA contains multiple forwarding nodes, the corresponding relationship of the multiple forwarding nodes can be dynamically adjusted. Therefore, by reconfiguring the corresponding relationship of these nodes, the damaged forwarding node can be bypassed and the data can be forwarded to other available forwarding nodes, which can reduce the need for equipment replacement caused by forwarding node damage and improve the stability and reliability of the system. Furthermore, the FPGA architecture of the present disclosure constructs an efficient and flexible network data processing platform by integrating multiple forwarding nodes.
