Abstract

The invention provides a fault processing method and device. The method comprises the following steps that interconnection nodes judge whether a multipoint fault exists on a primary ring when a public link on the primary ring where interconnection ports on the interconnection nodes are located has a fault, wherein the interconnection ports are ports on a public link of the primary loop and subrings, where the interconnection nodes are located; if the primary ring has the multipoint fault, the interconnection nodes determine the number of hops between the fault interconnection node and the interconnection node according to a signal fail SF message received from non-interconnection ports, wherein the non-interconnection ports are ports except for the interconnection ports on the primary loop; and if the number of hops is smaller than the reference number of hops between the interconnection nodes and master nodes, the interconnection nodes send an MS (Manual Switch) message on the ports of the subrings of the interconnection nodes and block the ports of the subrings on the interconnection nodes, so that the nodes of the subrings receiving the MS message open a blocked ring protection link RPL. According to the method and the device, a problem of blocked traffic of the subrings can be effectively solved.

Description

Technical field [0001] This application relates to the field of network technology, and in particular to a method and device for troubleshooting. Background technique [0002] Ethernet Ring Protection Switching (ERPS, Ethernet Ring Protection Switching) is a link layer protocol specifically applied to the Ethernet ring. When the Ethernet ring is complete, it can prevent broadcast storms caused by the data loop, and when a link on the Ethernet ring is disconnected, it can quickly restore the communication path between nodes on the ring network, and has a high convergence speed. [0003] The ERPS ring network includes four types of nodes: Owner node, Neighbor node, Normal node, and Interconnection node. The link between Owner node and Neighbor node is the ring network protection chain Road (RPL, Ring Protection Link), the node connecting the main ring and the sub-ring is an Interconnection node, and the others are all Normal nodes. Summary of the invention [0004] In view of this, ...
