Problems solved by technology

However, when resources are insufficient, rerouting cannot be successful, and 1+1 protection cannot be provided again
Guaranteed protection can only be provided once
[0012] 2) Excessive bandwidth resource occupation
[0013] As long as there are idle resources available, the permanent 1+1 service will always occupy double bandwidth resources, while other services may be interrupted due to lack of resources

Embodiment Construction

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. It should be understood that the described embodiments are only some of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0028] For most operators, two-time failure protection is a common requirement, while three-time failure protection requires too much network construction cost and low cost performance, so there is little demand. For the protection of two failures, general operators also require that they can provide service performance within 50ms, which requires that the protection for two failures should be guaranteed. The current per...

Abstract

A fault protection method in the field of the communications technologies includes: creating a working path and a protection path for a service to form 1 + 1 protection, and creating, for the service, a shared Mesh recovery path separate from both the working path and the protection path. When any one of the working path, the protection path, and the shared Mesh recovery path is faulty, two paths which are not faulty form the 1 + 1 protection. Embodiments of the present invention further provide a fault protection device.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a fault protection method and equipment. Background technique [0002] In order to transmit customer services, the optical network can establish a connection that meets the bandwidth requirements of customer services to transmit customer services. The bandwidth granularity of the optical network connection is large, and the reliability of the connection needs to be guaranteed within the network. [0003] Reliability is guaranteed by various protection and recovery techniques, such as 1+1 protection for optical network connections. 1+1 protection provides two connections for each customer service signal, one is called the working connection, and the other is called the protection connection. Send customer service signals to two connections, and choose to receive customer service from one of the connections according to the signal quality of the two connections at ...
