Problems solved by technology

[0009] Although the traditional service recovery time using the multiplex section protection mechanism is short, the average resource utilization rate can only be 50%. However, the method of using the shared MESH recovery mechanism can improve the resource utilization rate, but the service recovery time is shorter than the traditional multiplex section protection mechanism. The business recovery time of the segment protection mechanism is long, which cannot meet the customer's business requirements

Abstract

The embodiment of the invention discloses a method, a system and equipment for service recovery, which belong to the field of communication. The method comprises the following steps: setting the work resource of a traffic engineering link in a network in a sharing MESH recovery state; flooding the sharing MESH recovery state information into the network, wherein the sharing MESH recovery state information is used for notifying that the fault recovering mode of the work resource of the traffic engineering link is the segment level sharing MESH recovery; detecting whether the traffic engineering link has a fault or not; and recovering the service on the work resource of the traffic engineering link by switching N segment level forwarding adjacent label switching paths on the traffic engineering link to N corresponding segment level share MESH recovering paths when a fault is detected on the traffic engineering link. The technical scheme provided by the embodiment of the invention can reduce the service recovery time and meet the service requirement of a client when the bandwidth resource utilization is high.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a service recovery method, system and equipment. Background technique [0002] Automatically Switched Optical Network (ASON) introduces the control plane between the transmission plane and the management plane of the traditional optical network, so that it has the functions of automatic neighbor, automatic link and automatic topology discovery, and the rerouting of the control plane The mechanism is combined with protection mechanisms such as subnet connection protection and multiplex section protection of traditional optical networks, and can flexibly and automatically provide permanent 1+1 protection, 1+1 protection plus recovery, multiplex section protection plus recovery, shared MESH recovery, Various types of protection and recovery services such as dynamic recovery, no protection, and additional services. [0003] In order to effectively restore services when a failur...
