Abstract

The invention provides a path switching method, device and equipment and a readable storage medium. The method comprises the following steps: when a transmission path between two nodes has a fault, determining a maximum transmission rate supported by the two nodes, and determining a target transmission path group of which the transmission rate is the maximum transmission rate; if the available transmission paths exist in the target transmission path group, determining an optimal transmission path in the available transmission paths for the two nodes to perform path switching; and if the available transmission path does not exist, determining the next-level transmission rate supported by the two nodes, and executing the step of determining the target transmission path group of which the transmission rate is the maximum transmission rate by taking the next-level transmission rate as the maximum transmission rate. According to the method and the device, available resources on the networkcan be used more effectively and flexibly in a speed reduction path searching mode, and normal operation of high-speed service is guaranteed to the maximum extent.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular to a path switching method, device, equipment and readable storage medium. Background technique [0002] The automatic switching optical network is an optical transport network that realizes automatic switching and connection control through the control plane. As an operation network that provides users with various services, it must have high reliability for B100G large-capacity services, that is, the network must have strong self-healing and recovery capabilities. Once a fault point occurs, the network should have The ability to quickly adopt another route or other protection methods so that the services operating on it will not be affected or will be less affected. [0003] At present, when the transmission path between sites in the network fails, the service is generally restored through 1:1 protection or dynamic rerouting. If the service cannot be restored th...
