Abstract:
1. A ring network protection method, wherein the ring network comprises a plurality of nodes and any two adjacent nodes are connected by a link, the method comprising: receiving, by a node, a ring network protection switching request when a fault occurs in the ring network, wherein the ring network protection switching request carries information of a source node and a destination node of the ring network protection switching request; determining, by the node, a fault location according to the information of the source node and the destination node, and selecting a protection tunnel according to the determined fault location; and switching, by the node, services to the selected protection tunnel, wherein if the node is the destination node, and the fault is located in a link between the node and the source node, a link protection tunnel is selected as the protection tunnel for the link between the node and the source node; and if the node is not the destination node, and the fault is located at the destination node which is on a short way side between the node and the source node, a node protection tunnel is selected as the protection tunnel for the destination node.
