Abstract

The invention relates to APS method for shared VP- ring in ring network with ATM technology, which comprises: sending and receiving the APS cell defined with I.630 as reference and contained alert information and node space code address to detect logic link group state, realizing said protective switch to logic business with millisecond-level response speed; wherein, the switch is realized by modifying route list; when some node takes APS to self-ring business, the business of this ring also be automatic protection switched to match ring. This invention has less damage to business and high utility for bandwidth, and can match with APS of SDH.

Description

technical field

[0001] The invention relates to a method for realizing shared virtual path ring (VP-ring) protection switching in a ring network adopting asynchronous transfer mode (ATM) technology, and the method can realize the protection switching of millisecond-level response speed to logical layer services. Background technique

[0002] At present, the ring network using ATM technology is widely used to build a multi-service transmission platform (MSTP). Among them, ATM technology is mainly used to provide link layer functions with friendly interfaces with other layer protocols, because ATM has good quality of service (QOS) brought by multi-service levels, fast exchange brought by fixed cell length, and Efficient service transmission brought about by asynchronous statistical multiplexing, and supports dynamic and static connection-oriented call admission control (CAC), complete operation management and maintenance (OAM) functions, and supports reliable network flow cont...
