Method and system for carrying out service maintenance in smart optical network

Abstract

The present invention pertains to the technical field of Automatically Switched Optical Network (ASON), and provides a service maintenance method and system in an intelligent optical network. When a certain section of fiber link is necessary to be maintained in the network, a network management platform issues a link maintenance command to the both end nodes of the link. After receiving the link maintenance command, the nodes query the services on the link first, locate the head node of the service according to a service label, and transmit the link maintenance command to the head node, and then the head node initiates the service maintenance. By transmitting the link maintenance command to different head nodes, each head node initiates the maintenance command automatically one by one, and thereby all the services on the link are maintained, the complexity of the present link maintenance is avoided, the network management platform is only needed to issue the link maintenance command, all the service maintenance can be accomplished automatically, one bottleneck of the present batch service maintenance is solved, and the work efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of ASON (Automatically Switched Optical Network, intelligent optical network), in particular to a method and system for service maintenance in an intelligent optical network. Background technique [0002] With the rapid development of network informatization, the information volume of data services has shown explosive growth, and the sudden bandwidth requirements of data services have brought challenges to the semi-static mode of the transmission network. In this case, how to improve network resource utilization, reduce costs, and enhance resource utilization flexibility becomes very important. ASON can dynamically allocate network resources, is fast and flexible, can be scheduled, monitors network status in real time, and maximizes protection and recovery according to business priorities. It has become an important communication technology and is widely used today. [0003] ASON is an automatic swi...
