Abstract

This invention relates to a service / circuit protection and a recovery method by combining multiplex section protection and mesh recovery in an automatic exchange optical network, which is suitable for the combination of a linear multiplex section protection and a protection of two-fiber two-way multiplex section, shared protection ring and recovery of the mesh. In this method, the service / circuit are first automatically protected by the multiplex section protection method, that is to say applying linear multiplex section protection or two-fiber two-way multiplex section protection ring, when the multiplex section protection is unable to continue, the mesh recovery is started at once.

Description

technical field

[0001] The technical field of the present invention is a method for combining service / circuit protection and restoration in an automatic switching optical network, and specifically relates to a method for combining multiplex section protection and mesh network (Mesh) restoration for a service / circuit in an automatic switching optical network method. Background technique

[0002] With the demand for flexibility in service scheduling in optical networks, Automatically Switched Optical Networks (ASON, Automatically Switched Optical Networks) emerged as the times require. The automatic switched optical network can be implemented based on Synchronous Digital Hierarchy (SDH, Synchronous Digital Hierarchy) or Optical Transport Network (OTN, Optical Transport Network), and supports three connection modes: permanent connection, soft permanent connection and switched connection.

[0003] Another advantage of the ASON network is that it can provide Mesh network recover...
