Embodiment 1

[0057] This embodiment provides a super ring network structure for redundant backup, such as figure 1 , the super ring network structure has 4 ring networks RA-RD; all ring networks are connected to the same network N through redundant backup links; adjacent ring networks are connected to each other through candidate links, and those connected to the candidate links Nodes are candidate nodes, ports connected between ring networks are defined as candidate ports, and the initial forwarding states of candidate ports are BLOCK states;

[0058] The BLOCK state is forwarding protocol control packets, but not forwarding service data packets; when the candidate port is UP, the candidate node sends handshake information to the adjacent ring network according to a predetermined period, and the candidate node receives the adjacent ring network The handshake information sent by the candidate node updates the state information (forwarding state, active FORWARD, passive FORWARD) of the adja...

Abstract

The invention relates to a super ring network structure for redundant backup, which solves the technical problem of being unable to meet the requirements of high redundancy backup, by adopting a plurality of ring networks; the ring networks are connected to the second layer through redundant backup links Network connection: Adjacent ring networks are connected to each other through candidate links, nodes connected to candidate links are candidate nodes, ports connected between ring networks are defined as candidate ports, and the initial forwarding states of candidate ports are all BLOCK states; candidate When the candidate port is UP, the node sends handshake information to the adjacent ring network according to a predetermined period, and the candidate node receives the handshake information sent by the adjacent ring network, and updates the state of the adjacent ring network connected by the candidate link saved by the candidate node; The node sends a candidate node vector notification message through two ring ports, and the technical solution of electing the master candidate node in the ring network to which the candidate node belongs solves this problem better, and can be used in redundant backup applications of multiple ring networks.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a super ring network structure for redundant backup. Background technique [0002] The current ring network technology provides reliable network guarantee through redundant backup links when performing business communication between ring networks. [0003] For some application scenarios that require higher network reliability, the network topology is more complex. Multiple ring networks are connected to one network, and then the ring networks are connected together. The current ring network redundancy solutions cannot be realized. That is to say, each node in the ring network is required to be connected with a redundant backup link. [0004] To sum up, the existing redundant backup between ring networks has the technical problem of being unable to meet the application scenarios with higher requirements for redundant backup. Therefore, it is necessary to provide a ...
