Arbitrarily topological intersected ring network protecting method, node and intersected ring network

Abstract

The invention discloses an intersecting ring network protection method of arbitrary topology, the master node of each Ethernet ring network in the intersecting ring network is allocated with priority respectively, and the method comprises the following steps: the node of the Ethernet ring network obtains the master node belonging to an own port and the corresponding priority; the node of the Ethernet ring network reports fault notice to the master node with the highest priority that belongs to the fault condition port after monitoring the own port changes into fault condition; and the master node that receives the fault notice opens a secondary port. The invention also discloses a node and an intersecting ring network. The invention can provide an effective ring network protection mechanism for a plurality of intersecting Ethernet ring networks of arbitrary topology.

Description

technical field [0001] The invention relates to the technology of the Ethernet ring network, in particular to a method for protecting an intersecting ring network of any topology, a node and an intersecting ring network. Background technique [0002] At present, the Ethernet ring network is gradually popularized and applied. figure 1 It is a schematic diagram of the structure of a single Ethernet ring network. see figure 1 , in a single Ethernet ring network, including a master node and multiple transmission nodes, the master node and each transmission node transmit business data on the Ethernet ring network to complete various business functions. [0003] Since the Ethernet ring network is a ring network structure, it is necessary to prevent loops, so as to avoid broadcast storms caused by unknown unicasts and broadcasts being circulated on the ring. At present, for a single Ethernet ring network, there are relatively mature technologies to avoid loops and ensure data tr...
