Abstract

The embodiment of the application discloses a ring network anomaly protection method and device. The method may include the following steps: a first node determines that a first port of the first nodeexits an Ethernet ring protection switching protocol (ERPS) ring, wherein the process of exiting the ERPS ring is used for indicating that the first port does not process an ERPS protocol message inthe case of exiting the ERPS ring; the first node blocks a second port, wherein the second port is a port of the first node on the ERPS ring, and the second port is different from the first port; thefirst node sends a first terminal message to the second node, wherein the first node and the second node are both on the ERPS ring, the first node and the second node are different nodes, and the first terminal message is used to indicate that the first port of the first node exits the ERPS ring. By adopting the scheme of the application, the problem that some nodes in the ERPS ring in the prior art may not perform normal communication can be solved.

Description

technical field [0001] The present application relates to the technical field of network communication, in particular to a ring network abnormality protection method and device. Background technique [0002] The Ethernet Ring Protection Switching (Ethernet Ring Protection Switching, ERPS) protocol is a ring network protection protocol developed by the International Telecommunications Union (International Telecommunications Union, ITU), also known as G.8032. It is a link layer protocol specially applied to the Ethernet ring network. When the Ethernet ring network is complete, it can prevent the broadcast storm caused by the data loop. It is a protocol for the Ethernet link layer to break the loop. When the Ethernet ring network When a link on the network is disconnected, the communication between the nodes on the ring network can be quickly restored. [0003] ERPS takes the ERPS ring as the basic unit and includes several nodes. By setting the ring network protection link RP...
