Method and system for managing resource state in automatic exchange optical network

Abstract

The invention discloses a method and a system of implementing resource state management in an automatic switching optical network, wherein, the method comprises the following steps: S1, the local end node sends resource state detection request about a connecting label to the opposite end node; S2, the local end node receives the resource state detection information about a connecting label fed back by the opposite end node; S3, if the resource state detection information is not consistent with the resource state information recorded by the local end node, the connecting label is deleted or migrated. Compared with the prior art, the method of the invention increases a step of comparing the resource state detection information of the opposite end node with the resource state information of the local end node, if the comparison result is not consistent, the connecting label is deleted or migrated; the method increases a function of eliminating disaccord as well as intelligence of the automatic switching optical network, so that the detection has more instantaneity.

Description

technical field [0001] The invention relates to the field of automatic switching optical network, in particular to a method and system for realizing resource state management in automatic switching optical network. Background technique [0002] The concept of Automatic Switch Optical Network (ASON) was formally proposed in 2001; the basic feature is to introduce a relatively independent control plane in the traditional optical transport network to realize the on-demand allocation of network resources , so as to realize the intelligence of the optical network, including routing and signaling processing, signaling, connection control, protection and recovery, etc. The traditional optical transport network only has the transmission plane and the management plane. According to the ITU-TG.8080 recommendation, the distributed intelligent control plane included in the automatic switching optical network combines the transmission, switching and data networks together, realizing the ...

AI Technical Summary

Problems solved by technology

There are many reasons for resource state information inconsistency. For example, incomplete connection deletion operations will lead to resource state information inconsistency in automatic switching optical networks.

The inconsistency of these resource status information will lead to the waste of network resources and the confusion of resource management.
