Embodiment 1

[0059] This embodiment provides a ring network tunnel configuration system based on a shared path, the system mainly includes a path configuration module, and the path configuration module is used to configure a working tunnel based on a shared path with the downlink node of the service on the ring as the destination node , and the reverse closed protection tunnel corresponding to the working tunnel.

[0060] Further, the above path configuration module is configured to: establish a working tunnel from the adjacent node of the lower ring node to the node along the clockwise and / or counterclockwise direction of the ring;

[0061] A closed protection tunnel is established from the lower-loop node to the lower-loop node along the opposite direction of the working tunnel.

Embodiment 2

[0063] As shown in FIG. 2 , the ring network protection system provided by this embodiment mainly includes the following four modules: a path configuration module, a status detection module, a status notification module and a service switching module. Among them, the main functions of each module are described as follows:

[0064] The path configuration module is mainly used to configure a working tunnel from an adjacent node along the clockwise or counterclockwise direction of the ring to the current next-ring node with each downlink node of the business on the ring as the destination node. In addition, for The working tunnel is configured with a closed-loop protection tunnel (hereinafter referred to as a closed protection tunnel) in opposite directions to protect the working tunnel.

[0065] The state detection module is mainly used to detect the state of the link through the fault detection message of the link layer between two directly connected adjacent nodes on the ring ...

Abstract

The invention discloses a looped network tunnel configuration method and a looped network protecting method based on a shared path and a system thereof, which configure a work tunnel based on a shared path and a reverse closed protecting tunnel, taking a lower loop node of looped business as an aim node. According to the invention, a plurality of MP2P shared paths are established on one loop, each shared path can bear the business from the loop entering of one or a plurality of nodes to the loop exiting of one node so that the complexity of the configuration of the looped network is avoided, the performance of protective switching is improved, and the configuration is optimized.

Description

technical field [0001] The invention relates to the technical field of ring network protection, in particular to a ring network tunnel configuration method based on a shared path, a ring network protection method and a system. Background technique [0002] Currently in the ring network, for the Wrapping (loopback) protection scheme in the G.8132 standard, since each protected LSP (Label Switching Path, Label Switching Path) corresponds to a closed protection ring in this protection scheme, the configuration workload If the value is too large, there will be many switching operations, and the switching processing time will be relatively long. Contents of the invention [0003] The technical problem solved by the present invention is to provide a ring network tunnel configuration method based on a shared path, a ring network protection method and a system, optimize the ring network configuration, and improve the performance of protection switching. [0004] In order to solve...
