[0033] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0034] Before describing the message processing method of the MRP ring network of the present application, the structure of the MRP ring network 100 is first introduced accordingly.

[0035] Figure 1 A framework scenario diagram of the MRP ring network 100 of the embodiment of the present application is shown. Exemplarily, the MRP ring network 100 includes a media redundancy management terminal 110 and a plurality of media redundancy clients 120 constituting the ring network. Specifically, the media redundancy management terminal 110 plays the role of monitoring the loop and controlling the link in the MRP ring network 100. The media redundancy management terminal 110 is used to respond to the loop or link failure of the MRP ring network 100, and eliminate the loop when the loop is closed by blocking the port of its own device in the ring network or releasing the blocked port, and restore the communication link between nodes when a link in the ring network fails. The media redundancy client 120 is used to monitor the link status of the ring port on its own device, and notify the link change to the media redundancy management terminal 110, and the media redundancy management terminal 110 makes corresponding processing according to the link change. In the MRP ring network 100, all devices with MRP capabilities can be configured by the network administrator as a media redundancy management terminal 110 or a media redundancy client 120. However, at the same time, only one device can be in the working state of the media redundancy management terminal 110. The redundancy purpose is achieved by blocking one of the ports of the media redundancy management terminal 110.

[0036] In this embodiment, the MRP protocol message includes a test message, a offline frame message, an online frame message, and a topology state change frame message. The test message originates from the media redundancy management terminal 110, and the test message is used to determine whether the MRP ring network 100 forms a closed loop. Both the offline frame message and the online frame message originate from the media redundancy client 120. When the media redundancy client 120 detects that its own link fails, it sends the offline frame message. When the media redundancy client 120 detects that its own link failure is restored, it sends the online frame message to notify the media redundancy management terminal 110 of the link change detected by itself. The topology state change frame message originates from the media redundancy management terminal 110. The topology state change frame message is used to notify all media redundancy clients 120 of the topology change occurring in the MRP ring network 100. The media redundancy client 120 that receives the topology state change frame message will clear its own filtering database (Filtering Database, FDB) to facilitate re-learning the MAC (Media Access Control, Media Access Control) address after the topology change.

[0037] For example, in the MRP ring network 100, when the link status of the MRP ring network 100 is intact, the media redundancy management terminal 110 actively blocks one of its own ring ports to eliminate the loop of the MRP ring network 100, and the effect is as follows: Figure 1When a single point failure occurs in the MRP ring network 100, the ring port where the link failure occurs is in a physical link failure or disconnected state. At this time, the media redundancy management terminal 110 can quickly release the blocked ring port to ensure the connectivity of the ring network. The effect is as follows: Figure 2 shown.

[0038] For example, in one embodiment, the specific processing flow of the media redundancy client 120 and the media redundancy manager 110 in the MRP ring network 100 is as follows:

[0039] The media redundancy management terminal 110 periodically sends test messages outward through the two ring ports and sets the primary port to the forwarding state. If the media redundancy management terminal 110 receives the test message sent by itself from any ring port, it indicates that the MRP ring network 100 is closed, and the media redundancy management terminal 110 sets the secondary port to the blocking state to avoid broadcast storms. If the media redundancy management terminal 110 does not receive the test message sent by itself, it indicates that the MRP ring network 100 is in an open ring state, that is, the loop is disconnected, then the media redundancy management terminal 110 will also set the secondary port to the forwarding state to ensure that the communication link on the MRP ring network 100 is not interrupted. The media redundancy client 120 forwards the received MRP protocol message between the two ring ports, that is, the message received from one ring port will be forwarded on the other ring port, so that the MRP protocol message can circulate in the MRP ring network 100, so that the media redundancy management terminal 110 can receive the test message sent by itself to determine the state of the MRP ring network 100. When the media redundancy client 120 detects that a ring port link fails, it blocks the failed ring port and sends offline frame messages through the ring port; when the media redundancy client 120 detects that the ring port link fails, it temporarily blocks the restored ring port and maintains its blocking state to avoid loops, and sends online frame messages through the ring port. If a link in the MRP ring network 100 fails, all the media redundancy clients 120 connected to the link will detect that the ring port link fails.

[0040] When the media redundancy management terminal 110 receives a offline frame message, the media redundancy management terminal 110 immediately processes the offline frame message, sets the ring port that was originally in a blocked state to a forwarding state, and sends a topology state change frame message through two ring ports. When the media redundancy management terminal 110 receives an online frame message, the media redundancy management terminal 110 immediately processes the online frame message, directly sets its own secondary port to a blocked state, and sends a topology state change frame message through two ring ports. When the media redundancy client 120 receives a topology state change frame message, it will release the temporarily blocked port and clear the local filtering database to re-learn the MAC address after the topology change. It can be understood that the media redundancy management terminal 110 can quickly process the link state change in the MRP ring network 100, shortening the convergence time of the MRP ring network 100 failure.

[0041] Figure 3 A flow chart of a message processing method of an MRP ring network according to an embodiment of the present application is shown. Exemplarily, the message processing method of the MRP ring network is applied to a media redundancy client 120, and specifically includes the following steps:

[0042] S210 , receiving an MRP protocol message sent by the previous media redundancy client 120 or the media redundancy manager 110 .

[0043] S220 , matching the first target message or the second target message based on the access control list, wherein the first target message comes from the media redundancy management terminal 110 , and the second target message comes from the media redundancy client 120 .

[0044] In this embodiment, the first target message is a topology state change frame message sent by the media redundancy management terminal 110, and the second target message is a offline frame message or an online frame message sent by the media redundancy client 120. The first target message and the second target message have the same destination address and Ethernet type.

[0045] Exemplarily, the media redundancy client 120 uses a switch equipped with an integrated circuit (Application Specific Integrated Circuit, ASIC) chip to perform second and third layer forwarding. In the integrated circuit chip, there is an access control list resource. The integrated circuit chip can customize the forwarding rules of the messages entering the chip through the access control list. The preset matching rule is set to the same destination address and Ethernet type as the first target message and the second target message, so that the integrated circuit chip can match the first target message or the second target message through the access control list.

[0046] In one embodiment, the access control list includes preset matching rules constructed based on the destination addresses and Ethernet types of the first target message and the second target message. The message processing method matches the first target message or the second target message based on the access control list, including: matching the destination address and Ethernet type of the received MRP protocol message with the preset matching rules to match the first target message or the second target message.

[0047] Specifically, the access control list, as a chip resource of the integrated circuit chip, is a hardware acceleration module for network access control. In the access control list, the preset matching rules can be used to filter out the messages that do not meet the conditions in the MRP protocol message. When the integrated circuit chip receives the MRP protocol message, it will search and match the destination address, source address, Internet Protocol address, port number and Ethernet type of the MRP protocol message, and compare the matching results with the preset matching rules defined in the access control list to determine whether the MRP protocol message should be allowed to be forwarded or should be filtered out.

[0048] S230 , forwarding the matched first target message or the second target message to the next media redundancy client 120 or the media redundancy management terminal 110 by hardware, and clearing its own filtering database according to the matched first target message.

[0049] Exemplarily, the integrated circuit chip is used to quickly forward the matched first target message or the second target message to the next adjacent media redundancy client 120 or the media redundancy management terminal 110 of the MRP ring network 100, without relying on the processor to forward the first target message or the second target message. The integrated circuit chip is also used to forward the matched message to the processor, so that the processor performs a clearing and filtering database operation according to the received topology state change frame message.

[0050] For example, in one embodiment, the media redundancy client 120 is a switch provided with an integrated circuit chip, and the message processing method performs hardware forwarding of the matched first target message or the second target message to the next media redundancy client 120 or the media redundancy management end 110, including: sending the matched first target message or the second target message to its own output port through the integrated circuit chip, so that the output port sends the first target message or the second target message to the next media redundancy client 120 or the media redundancy management end 110.

[0051] For example, in one embodiment, the message processing method clears its own filtering database according to the matched first target message, including: sending the matched first target message to the processor, so that the processor generates a clearing instruction of the filtering database according to the first target message to clear the filtering database.

[0052] Specifically, the access control action of the access control list is set to send the first target message or the second target message to the output port and the processor. After matching the preset matching rule defined in the access control list, the integrated circuit chip processes according to the access control action, so that the processor receives the topology state change frame message and performs a clear filtering database operation. It can also enable the topology state change frame message, offline frame message and online frame message to be directly forwarded from the ring network output port of the integrated circuit chip without the need for forwarding by the processor.

[0053] It can be understood that the optimization of the convergence performance of the MRP ring network 100 is mainly that the media redundancy management terminal 110 no longer needs to use a processor to forward messages, but relies on the access control list of the integrated circuit chip to achieve that the media redundancy management terminal 110 in the MRP ring network 100 can quickly receive the offline frame message or the online frame message forwarded by the media redundancy client 120, and send the topology state change frame message to all media redundancy clients 120. At the same time, each media redundancy client 120 can also quickly receive the topology state change frame message forwarded by other media redundancy clients 120, and perform clearing and filtering database operations, thereby improving the convergence performance of the MRP ring network 100. When there are a large number of MRP switching devices in the ring, the time for each device to receive the message can be accelerated, thereby speeding up the response processing of each device to the MRP protocol message, and improving the convergence time. Moreover, the message processing method of the MRP ring network is highly universal for switch equipment. Basically, existing switch products use integrated circuit chips for layer 2 and layer 3 data forwarding. At the same time, the access control list is a basic function of the integrated circuit chip. There is no need to add related hardware equipment. Therefore, the applicability of this application is strong.

[0054] The present application also provides a terminal device. Exemplarily, the terminal device includes a processor and a memory, wherein the memory stores a computer program, and the processor runs the computer program, thereby enabling the terminal device to execute the above-mentioned MRP ring network message processing method or the functions of each module in the above-mentioned MRP ring network 100.
