Method and node for service to occupy protected resource in shared protection

摘要

Disclosed are a method and node for a service to occupy protection resources in shared protection, including: when receiving a command or service state information, a node responding to the command or service state and allocating protection resources to a corresponding service in accordance with a priority order of a first-level manual command, a service signal failure, a service signal degradation and a second-level manual command. By integrating priorities of the manual command and the service state, the embodiments of the present document formulate a set of unified priority rules, reducing the information stored on nodes in a mesh network, and simplifying the processing procedure of the mesh network.
