[0044] In the description of this application, unless otherwise specified, " / " indicates that the objects associated before and after are in an "or" relationship, for example, A / B can represent A or B; "and / or" in this application is merely a description of the association relationship of associated objects, indicating that three relationships may exist, for example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural.

[0045] In the description of this application, unless otherwise specified, "plurality" means two or more than two. "At least one of the following" or similar expressions refers to any combination of these items, including any combination of single or plural items. For example, at least one of a, b, or c can mean: a, b, c, ab, ac, bc, or abc, where a, b, and c can be single or plural.

[0046] In addition, to facilitate the clear description of the technical solutions of the embodiments of the present application, in the embodiments of the present application, the words "first" and "second" are used to distinguish between identical or similar items with substantially the same functions and effects. Those skilled in the art will understand that the words "first" and "second" do not limit the quantity or execution order, and the words "first" and "second" do not necessarily mean different.

[0047] In the embodiments of this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of this application should not be construed as being preferred or advantageous over other embodiments or designs.

[0048] It will be understood that the “embodiment” mentioned throughout the specification means that the specific features, structures or characteristics related to the embodiment are included in at least one embodiment of the present application. Therefore, the various embodiments throughout the specification do not necessarily refer to the same embodiment. In addition, these specific features, structures or characteristics can be combined in one or more embodiments in any suitable manner. It will be understood that in the various embodiments of the present application, the size of the sequence number of each process does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiment of the present application.

[0049] It is understood that some optional features in the embodiments of the present application may, in certain scenarios, be implemented independently of other features, such as the solution on which they are currently based, to solve corresponding technical problems and achieve corresponding effects. They may also be combined with other features in certain scenarios as needed. Accordingly, the devices provided in the embodiments of the present application may also implement these features or functions accordingly, which will not be described in detail here.

[0050] In this application, unless otherwise specified, the same or similar parts between the various embodiments can be referenced to each other. In this application, unless otherwise specified and there is no logical conflict between the various embodiments, the terms and / or descriptions between different embodiments are consistent and can be referenced to each other. Different embodiments can be combined to form new embodiments based on their inherent logical relationships. The following implementation methods of this application do not constitute a limitation on the scope of protection of this application.

[0051] When forwarding data, network devices can adopt either a distributed or centralized architecture. A distributed architecture integrates a hardware forwarding module into every interface card or line card in the network device. This hardware forwarding module can be an application-specific integrated circuit (ASIC) or a neural processing unit (NPU). Each line card can perform forwarding, even independently. This architecture is called a distributed architecture. Network devices no longer require a dedicated forwarding module to serve the forwarding function of the entire network device. Instead, each line card can perform Ethernet / routing table query and forwarding through the forwarding module / chip, enabling independent forwarding on the line card.

[0052] A centralized architecture means that the network device has a dedicated hardware forwarding module to forward data packets for the network device. This hardware forwarding module can be an ASIC or NPU. Each interface board / line card module of the switch, such as the peripheral component interconnect (PIC) or line processing unit (LPU), does not have Ethernet / routing processing capabilities. Data packets need to be sent from the line card to the centralized forwarding module to query the Ethernet / routing forwarding table for forwarding. The constraint of the centralized forwarding architecture is that the forwarding performance of the entire device is limited by the capabilities of the hardware forwarding module / chip on its centralized forwarding module. In the case of a centralized forwarding architecture, if the forwarding module fails, the forwarding capability of the entire switch device will be lost. Therefore, reliability needs to be ensured through redundancy of the forwarding module.

[0053] With the improvement of forwarding chip capabilities, centralized architecture is increasingly being applied in various scenarios and industries. Compared with distributed architecture, centralized architecture has the following advantages:

[0054] 1. The forwarding model is simple, the complexity is low, and the control plane has stronger processing performance;

[0055] 2. Line cards are simple, low cost, and have low failure rates;

[0056] 3. No need to exchange network cards, reducing failure points;

[0057] 4. The forwarding module supports 1:1 redundant backup and has high switching performance.

[0058] like Figure 1 As shown in the figure, for centralized frame-type network devices, the forwarding chip is typically located in the network device's main controller. To achieve high reliability, network devices typically use a 1:1 backup of the forwarding chips in two main controllers. If the active main controller fails, the network device quickly switches to the backup main controller. In this scenario, because both the active and backup main controllers are always active, the backup main controller's forwarding capability effectively operates in a backup forwarding state, reducing the network device's chip forwarding resource utilization.

[0059] For example Figure 2 As shown in the figure, the bandwidth capacity of the master forwarding chip is M Tbps. If the system has N slots, the maximum forwarding capacity is M Tbps when fully populated, and the average forwarding bandwidth per slot is M / N Tbps. Under normal operating conditions, the forwarding chips of the two MPUs are backed up in a 1:1 redundant backup, and the forwarding capacity of the backup master is not used, resulting in low overall chip forwarding resource utilization in the network device.

[0060] An embodiment of the present application provides a data forwarding method, which can provide multiple forwarding modes and has a forwarding mode that can improve forwarding bandwidth. The method includes: obtaining forwarding mode information, the forwarding mode information indicating a mode in which a network device processes forwarded data, the forwarding mode indicated by the forwarding mode information including a flexible forwarding mode; determining a forwarding mode according to the forwarding mode information; receiving at least one first forwarding data through at least one first interface board, and receiving at least one second forwarding data through at least one second interface board; in the flexible forwarding mode, transmitting at least one first forwarding data to at least one first forwarding chip, and transmitting at least one second forwarding data to at least one second forwarding chip; in the flexible forwarding mode, transmitting at least one first forwarding data to at least one first interface board and at least one second interface board through at least one first forwarding chip, and transmitting at least one second forwarding data to at least one first interface board and at least one second interface board through at least one second forwarding chip.

[0061] like Figure 3 As shown, the data forwarding method in the embodiment of the present application can be applied to Figure 3The network device shown includes a first main control board MPU1 (i.e., a first forwarding device) and a second main control board MPU2 (i.e., a second forwarding device). The first main control board includes a first processor CPU1, a first forwarding chip LSW1, a first interface board 1 and its corresponding first slot Slot1, a first interface board 2 and its corresponding second slot Slot2. The second main control board includes a second processor CPU2, a second forwarding chip LSW2, a second interface board 1 and its corresponding third slot Slot3, a second interface board 2 and its corresponding fourth slot Slot4.

[0062] The first processor CPU1 is used to control the corresponding first main control board to forward data, and the second processor CPU2 is used to control the corresponding second main control board to forward data.

[0063] The first forwarding chip LSW1 and the second forwarding chip LSW2 are used to forward received forwarding data according to a specified forwarding mode.

[0064] The first interface board 1 and the corresponding first slot Slot1, the first interface board 2 and the corresponding second slot Slot2, the second interface board 1 and the corresponding third slot Slot3, and the second interface board 2 and the corresponding fourth slot Slot4 are used to send and receive forwarding data.

[0065] It can be understood that the network device in the embodiment of the present application may include two main control boards. In addition, it may also include more main control boards, which is not limited here.

[0066] It can be understood that the main control board of the network device in the embodiment of the present application may include a forwarding chip. In addition, it may also include more forwarding chips. Each forwarding chip can forward data according to the indicated forwarding mode, which is not specifically limited here.

[0067] It can be understood that a main control board of the network device in the embodiment of the present application may include two interface boards, each interface board includes a corresponding slot, each slot may include multiple ports, and in addition, more interface boards and corresponding slots may be included, and each interface board and corresponding slot can send and receive forwarding data. The specific details are not limited here.

[0068] It is understood that in the embodiments of the present application, the execution subject may perform some or all of the steps in the embodiments of the present application. These steps or operations are merely examples, and the embodiments of the present application may also perform other operations or variations of various operations. In addition, the various steps may be performed in a different order than those presented in the embodiments of the present application, and it is possible that not all operations in the embodiments of the present application need to be performed.

[0069] It should be noted that the message names between the devices or the names of the parameters in the messages in the following embodiments of the present application are only examples. Other names may be used in specific implementations, and the embodiments of the present application do not specifically limit this.

[0070] like Figure 4 As shown, an embodiment of the present application provides a data forwarding method, the method comprising:

[0071] 401. The network device obtains forwarding mode information.

[0072] The network device obtains forwarding mode information, which indicates a mode for the network device to process received forwarding data. That is, the forwarding mode information indicates a forwarding mode, and the network device will forward the received forwarding data according to the forwarding mode.

[0073] In the embodiment of the present application, the forwarding mode information may include a flexible forwarding mode and a fault forwarding mode.

[0074] like Figure 5 As shown, this flexible forwarding mode can instruct the main control board in the network device to flexibly call all interface boards to forward received forwarding data. For example, forwarding data received by the first main control board can be sent out through the slot of the second main control board, or forwarded out through the slot of the first main control board.

[0075] like Figure 6 As shown, this fail-forwarding mode can indicate that a portion of the network device's forwarding functions has failed. The network device then processes received forwarding data using the remaining normal forwarding functions. For example, if the forwarding chip on the second main control board fails, the received forwarding data can be transmitted to the first main control board for processing. After receiving the forwarding data, the first main control board can use the slots of the first and second main control boards to perform forwarding processing.

[0076] like Figure 7 As shown, in addition to this, the forwarding mode information may also include other forwarding modes, for example, the forwarding mode information may also include a standard forwarding mode, which may instruct the network device to forward the received forwarding data according to a preset forwarding path. For example, the standard forwarding mode sets that all forwarding data received by the slot of the first main control board is transmitted to the forwarding chip of the first main control board, and the forwarding chip of the first main control board forwards all the received forwarding data through the slot of the first main control board. The same is true for the second main control board. All forwarding data received by the slot of the second main control board is transmitted to the forwarding chip of the second main control board, and the forwarding chip of the second main control board forwards all the received forwarding data through the slot of the second main control board.

[0077] Specifically, the network device may obtain the forwarding mode information by having a CPU of a main control board of the network device receive the forwarding mode information, where the forwarding mode information indicates a forwarding mode for the main control board to perform data forwarding. After receiving the forwarding mode information, the CPU of the main control board may send a forwarding mode control instruction to a forwarding chip of the main control board, where the forwarding mode control instruction instructs the forwarding chip to forward the forwarding data according to the forwarding mode indicated by the forwarding mode information.

[0078] In one possible implementation, the CPU of the main control board can send forwarding mode control instructions to the forwarding chip of the main control board. In addition, the CPU of the main control board can also directly send the received forwarding mode information to the forwarding chip of the main control board, and the forwarding chip forwards data according to the forwarding mode indicated by the forwarding mode information.

[0079] In an embodiment of the present application, the forwarding mode information received by the CPU of the main control board of the network device may be sent to the network device by other devices, or the user may perform related operations on the network device, and other modules of the network device may generate the forwarding mode information and transmit it to the CPU of the main control board of the network device. In addition to this, other acquisition methods may also be used, which are not limited here.

[0080] In the embodiments of the present application, it can be understood that the forwarding mode of the network device and the network forwarding device of the network device can be controlled by forwarding mode information.

[0081] 402. The network device receives first forwarded data and second forwarded data.

[0082] The network device receives the first forwarding data and the second forwarding data through the slot of the interface board.

[0083] Specifically, the network device in the embodiment of the present application includes two main control boards (i.e., network forwarding devices), and multiple slots (e.g., Slot 1 to Slot 4) of the two main control boards can receive forwarding data. For example, the first interface board 1 can receive first forwarding data, and the second interface board 1 can receive second forwarding data.

[0084] In the embodiments of the present application, forwarded data refers to data that needs to be forwarded by the network device. The forwarded data can be a single piece of data or a group of data; it can be forwarded in a packaged form or in batches, and the specific details are not limited here. Therefore, it can be understood that the network device receives the first forwarded data and the second forwarded data once or multiple times, and the specific details are not limited here.

[0085] In the embodiment of the present application, the network device receiving the first forwarding data and the second forwarding data is taken as an example for explanation. In addition, the network device can also receive one or more amounts of forwarding data, which is not specifically limited here.

[0086] 403. According to the forwarding mode, the interface board of the network device transmits the received first forwarding data and second forwarding data to the forwarding chip.

[0087] According to the forwarding mode indicated by the forwarding mode information, the interface board of the network device transmits the received first forwarding data and second forwarding data to the forwarding chip.

[0088] like Figure 5 As shown, specifically, when the forwarding mode indicated by the forwarding mode information is a flexible forwarding mode, the first interface board of the network device transmits the first forwarding data to the first forwarding chip; the second interface board of the network device transmits the second forwarding data to the second forwarding chip.

[0089] like Figure 6 As shown, specifically, when the forwarding mode indicated by the forwarding mode information is a fault forwarding mode, and the fault is a fault of the second forwarding chip, the first interface board of the network device transmits the first forwarding data to the first forwarding chip; the second interface board of the network device also transmits the second forwarding data to the first forwarding chip; thereby, the fault of the second forwarding chip does not affect the network device's forwarding of the second forwarding data.

[0090] Specifically, when the forwarding mode indicated by the forwarding mode information is a fault forwarding mode and the fault is a failure of the first forwarding chip, the second interface board of the network device transmits the second forwarding data to the second forwarding chip; the first interface board of the network device also transmits the first forwarding data to the second forwarding chip; thereby, the failure of the first forwarding chip does not affect the network device's forwarding of the second forwarding data.

[0091] like Figure 7 As shown, specifically, when the forwarding mode indicated by the forwarding mode information is the standard forwarding mode, the first interface board of the network device transmits the first forwarding data to the first forwarding chip; the second interface board of the network device transmits the second forwarding data to the second forwarding chip.

[0092] 404. According to the forwarding mode, the forwarding chip of the network device transmits the forwarding data to the interface board.

[0093] According to the forwarding mode, the forwarding chip of the network device transmits the received first forwarding data and second forwarding data to the first interface board and / or the second interface board, that is, the forwarding chip can call all slots of the network device to forward the first forwarding data and the second forwarding data.

[0094] Specifically, if Figure 5 As shown, when the forwarding mode is flexible, the first forwarding chip of the network device transmits the first forwarding data to the first interface board and / or the second interface board; the second forwarding chip of the network device transmits the second forwarding data to the first interface board and / or the second interface board. That is, in flexible forwarding mode, both the first and second forwarding chips can call on all interface boards of the network device to forward forwarding data. The first forwarding chip on the first main control board can call on the second interface board on the second main control board to forward data, and the second forwarding chip on the second main control board can also call on the first interface board on the first main control board.

[0095] like Figure 6 As shown, specifically, when the forwarding mode is the fault forwarding mode and the fault is the failure of the second forwarding chip, the network device will send all received forwarding data to the first forwarding chip, and then the first forwarding chip can call the first interface board and the second interface board to transmit the received first forwarding data and second forwarding data to the first interface board and / or the second interface board.

[0096] Specifically, when the forwarding mode is the fault forwarding mode and the fault is the failure of the first forwarding chip, the network device will send all received forwarding data to the second forwarding chip, and then the second forwarding chip can call the first interface board and the second interface board to transmit the received first forwarding data and second forwarding data to the first interface board and / or the second interface board.

[0097] like Figure 7 Specifically, when the forwarding mode is the standard forwarding mode, after the first forwarding chip receives the first forwarding data, it can call the first interface board to transmit the received first forwarding data to the first interface board. After the second forwarding chip receives the second forwarding data, it can call the second interface board to transmit the received second forwarding data to the second interface board.

[0098] In the implementation of this application, it can be understood that the forwarding chip of the network device transmits the forwarding data to the interface board, which is essentially calling the interface board and its slot to send the forwarding data to other devices. Therefore, after the interface board and its slot receive the forwarding data, they will send the forwarding data to other devices.

[0099] In the embodiment of the present application, the slots corresponding to the first forwarding chip LSW1 include the first slot Slot1 and the second slot Slot2. Each slot can include multiple ports. That is, all ports in the first slot Slot1 and the second slot Slot2 are ports corresponding to the first forwarding chip LSW1. It is understood that all ports in the third slot Slot3 and the fourth slot Slot4 are ports corresponding to the second forwarding chip LSW2.

[0100] In addition, the ports in each slot can also partially correspond to the first forwarding chip LSW1 and partially correspond to LSW2. For example, the first slot Slot 1 includes eight ports, port 1 through port 8. In the first slot Slot 1, ports 1 through port 4 correspond to LSW1, and ports 5 through port 8 correspond to LSW2. The ports in other slots can also be similar to the ports in the first slot, with some corresponding to the first forwarding chip LSW1 and others corresponding to LSW2.

[0101] In the case where part of the port in each slot corresponds to the first forwarding chip LSW1 and the other part corresponds to LSW2, since the ports corresponding to LSW1 include the ports from the first slot Slot1 to the fourth slot, and the ports corresponding to LSW2 also include the ports from the first slot Slot1 to the fourth slot, the data forwarding method of the embodiment of the present application can be distinguished by the specific port in actual execution. Port 1 of the first slot Slot1 may execute the forwarding method of LSW1, and port 2 of the first slot Slot1 may execute the forwarding method of LSW1. Specifically, Figure 8A As shown in the figure, the first slot Slot1 includes 6 ports, port 1 to port 6. Ports 1 to port 3 are the ports corresponding to LSW1, and ports 4 to port 6 are the ports corresponding to LSW2. In flexible forwarding mode, ports 1 to port 3 will transmit the received data to LSW1, and ports 4 to port 6 will transmit the received data to LSW2. LSW1 can transmit the received data to all ports of the first slot Slot1, and LSW2 can also transmit the received data to all ports of the first slot Slot1. Figure 8B As shown, in the embodiment of the present application, the network device can provide multiple forwarding modes including flexible forwarding mode and standard forwarding mode in normal working state, and the network device can flexibly switch between these forwarding modes. Figure 8B As shown, the network device can switch between the flexible forwarding mode and the standard forwarding mode. It is understandable that for multiple network forwarding devices in a network device, the network device can control them to switch forwarding modes, and the specific implementation method will not be repeated.
