Problems solved by technology

[0012] Using this method can avoid message loss and ensure high system reliability. However, sending a large number of control messages will consume high Link bandwidth and limited CPU resources, especially when multiple protection domains are configured, the resulting large number of control packets will seriously affect system performance

Embodiment Construction

[0029] In the Ethernet protection system, in order to improve system reliability under the premise of avoiding the loss of control messages, the method adopted in the implementation of this application is: a network node receives a control message sent by any other network node, and the control message carries the sequence number used to identify the control message; the network node performs protocol processing on the received control message, and after the processing is completed, constructs a response message for the control message, and passes the response message The message carries the serial number of the control message, and identifies the message type of the control message; the network node sends the response message to any other network node, and passes the response message The carried sequence number and the identified message type instruct any other network node to stop sending the control message.

[0030] The Ethernet protection system contains several protectio...

Abstract

The application discloses a method for processing a control message in an Ethernet protection system, which comprises the following steps: a network node receives a control message sent by any other network node in the same protection domain with the network node; the network node performs the protocol processing of the received control message and creates a response message for the control message, wherein the response message carries the sequence number of the control message and identifies the message type of the control message; and the network node sends the response message to a network node which sends the control message to the network node, and instructs the network node to stop sending the control message through the sequence number carried by the response message and the identified message type. Thus, the resource consumption of the system is greatly reduced and the stability and the reliability of the system are improved on the basis of avoiding message loss. The application also discloses a communication device and an Ethernet protection system.

Description

technical field [0001] This application relates to the field of Ethernet automatic protection, in particular to a method, device and system for processing control messages in an Ethernet protection system. Background technique [0002] In order to improve the security of Ethernet, under the prior art, in the Ethernet protection system, multiple protection domains are set up, taking one protection domain as an example, refer to figure 1 As shown, a protection domain is usually composed of a master node (Master) and a slave node (Slave). Each protection domain can implement a service virtual local area network (Virtual Local Area Network, VLAN) function for forwarding user data services, and a control VLAN function for forwarding protocol packets. Such as figure 1 As shown, the master node and the slave node form a dual-node dual-uplink system, and they are mutual backups. In a stable state, that is, when the link is intact, the master node blocks the protection service VLAN...
