Problems solved by technology

Due to the delay between failure detection and completion of the recovery mechanism, it is likely that a failure that has been recovered at the lower layer will be restored at the client level and switched to another recovery path
The second switchover caused temporary interruption of the restored connection and unnecessary occupation of idle resources at the client layer
However, the disadvantage of this concept is that it is more complex and the functionality of existing equipment must be changed

Embodiment Construction

[0078] The specific embodiment of the present invention is described below in conjunction with accompanying drawing:

[0079] In terms of an integrated multi-layer survivability strategy based on inter-layer signaling, each method in the prior art has disadvantages. So some new methods must be developed. Interlayer signaling is a promising approach. This policy is composed of inter-layer information interaction. Through inter-layer information interaction, the action of another layer is prohibited for the same fault when another layer is activated. The main problem with this approach is to create an inter-layer signaling system, since the standard signaling interface of the adjoining network layer can convey information related to failure recovery. In the past, only simple maintenance information, such as AIS information, was sent from the service layer to the client layer to allow easy fault location, but no information was available to the client layer about the progress o...

Abstract

The invention provides a multi-layer network fault recovery method, which obtains multi-layer network fault information in real time; determines the fault recovery initiation layer according to the fault information; performs intra-layer fault recovery; performs inter-layer fault recovery; thereby realizing multi-layer network fault recovery. Layer network failure recovery. The present invention is used to realize the coordination between integrated control of multi-layer transmission and multi-layer network fault recovery strategies, which can eliminate the incoordination of recovery actions caused by lack of information interaction mechanism between multi-layer fault recovery strategies and Many disadvantages caused by this improve the multi-layer network fault recovery capability.

Description

technical field [0001] The invention relates to communication network technology, in particular to the coordination of failure recovery of multi-layer transmission network structure under multi-technology network environment, specifically a method for recovery of multi-layer network failure. Background technique [0002] In the past ten years, due to the popularization and development of the Internet, the traffic volume centered on data has continued to grow, which puts forward new network requirements for the current communication network, especially in the field of network survivability. As a key networking issue, network reliability is becoming more and more important. Different technologies (such as: ATM, SDH and WDM technology) When integrated into a multi-layer transport network, many inter-layer coordination problems arise. One of the main problems is the multi-layer network survivability problem. [0003] Multi-layer network survivability refers to the nesting of s...
