Description

Ring network configuration detection method and device

technical field

The embodiment of the present invention relates to the technical field of Ethernet, and in particular to a ring network configuration detection method and device.

Background technique

With the widespread application of Ethernet in LANs, the scale of Layer 2 networks is getting larger and larger, and the commonly used spanning tree technology is insufficient in terms of expansion and convergence speed. Extreme company proposed the ERPS protocol ring network protection technology in 2003, achieving 50ms switching performance. The basic idea of Ethernet ring network protection: by simplifying the network, decomposing the network into the most basic unit of the ring, simplifying the calculation, and finally achieving the purpose of fast convergence. The emergence of ERPS technology has solved the problem of spanning tree very well. ERPS Ethernet ring network protection protocol is a special link layer protocol, which is specially used to construct ring-shaped Ethernet topology. The Ethernet ring network protection protocol blocks a link when the ring network topology is complete, preventing data loops from forming broadcast storms. In the event of a link termination, the protocol quickly restores the previously blocked link to restore communication between the nodes of the ring network. It can well meet the convergence speed requirements of the telecom level and the redundant backup function of the network.

ERPS technology divides single ring, multi-ring and non-closed ring according to network planning. In the ring, the control VLAN is used to transmit protocol messages. A master node and neighbor nodes will be set up. The master node and neighbor nodes are directly connected to form a ring network protection chain. Under normal circumstances, the protection link is in a blocking state, so as to achieve the purpose of breaking the layer 2 loop. When a link or node failure occurs, the node that detects the failure transmits the failure step by step. When the master node receives the failure signal, it will release the blocked link and switch the traffic to the backup link to complete convergence.

However, in the ERPS technology, the network management cannot know whether the configuration of the nodes in the ring network is correct, which leads to the inability to communicate in the ring network due to the wrong configuration of the nodes.
