Routing switching method and device for ring optical transmission network

Abstract

The invention discloses a route switching method and device for a ring-shaped optical transmission network. The method includes: when the output voltage of the power supply of the monitored base station is lower than a predetermined voltage threshold, according to the monitored optical route that works normally, the base station is connected to the The two normally working optical routes connected to two adjacent base stations are switched to the direct connection of the two optical routes, so that once it is detected that the base station is about to be powered off, the base station can be withdrawn from the ring optical transmission network, and the base station will be connected with the base station The two adjacent base stations are directly connected, the processing process can be automatically executed, the processing process is fast and effective, and has almost no impact on the network operation, thereby avoiding the simultaneous existence of a base station in the ring optical transmission network in the prior art that cannot work, and Another power outage at the base station will lead to the decommissioning of the entire optical ring network. The solution is inefficient, time-consuming, and significantly affects the operation of the ring optical transmission network.

Description

technical field [0001] The invention relates to an optical transmission network, in particular to a routing switching method and device for a ring optical transmission network. Background technique [0002] At present, the structure of the optical transmission network is usually a ring network (commonly called an optical ring network), and each node in the ring network can be a base station or other network equipment, and the function of network switching can be realized conveniently through the ring network structure. For example, if a base station fails in the ring network, the original transmission direction will be switched in the reverse direction of the original transmission direction, so as to ensure service continuity. [0003] However, in the optical ring network, if a base station fails to work due to equipment failure or optical routing failure, and another base station loses power when the failure is not repaired, at the moment when the base station loses power a...
