Embodiment Construction

[0047] The embodiment of the present invention provides a method for ensuring the reliable operation of the Ethernet ring network. When the master node is restarted, an Ethernet ring network state is added on the basis of RFC3619, that is, the restart state (Link-Start-State) to ensure reliable operation of the network. Among them, the structure of a logical domain in the Ethernet ring network can be found in figure 1 , where the number of nodes in each domain depends on actual needs, not limited to figure 1 four as shown in , but there is one and only one master node in each domain. figure 1 Among them, S2 is the master node, S1, S3 and S4 are the transmission nodes, and the ports on the ring of S2—the master port (P) and the slave port (S) are as follows: figure 1 As shown in , the two ports (1, 2) of the transmission node are not divided into master and slave. When the link is intact, the link state recorded by the nodes on the ring is the intact state (Link-Up-State), a...

Abstract

The invention discloses a method and device for guaranteeing reliable operation for Ethernet ring. Main node is restarted by following steps: main node of Ethernet ring network acquires network state before restarting and network configuration information after restarting; the main node blocks the data relay function of control VLAN of self ring port and protection service VLAN, adds the ring port in control VLAN and protection service VLAN; the ring port comprises main port and slave port; data relay function is opened for control VLAN of ring port; the link state is detected for validating entirety; protection service VLAN data relay function of ring port or main port is opened according to the detection result; other node is notified to update MAC address list. The inventive method effectively guarantees normal and reliable operation of Ethernet Ring network.

Description

technical field [0001] The invention relates to the field of network technology, in particular to an automatic protection technology of an Ethernet ring network, a method and a device for ensuring reliable operation of the Ethernet ring network when a master node in the Ethernet ring network is restarted. Background technique [0002] With the rapid development of the Internet, IP networks have gradually become an indispensable tool in people's daily work and life. RFC3619 defines an Ethernet Automatic Protection Switching (Ethernet Automatic Protection Switching, EAPS) method, which solves the problem of Ethernet equipment The problem of slow convergence of faults occurs in the ring network topology, and the method can make the convergence time within 50ms. This method defines some basic concepts. Each EAPS physical ring is composed of multiple nodes connected. According to different functions, the nodes are divided into transmission nodes and master nodes. Multiple logica...
