Method and system for carrying out service maintenance in automatically switched optical network

Abstract

The invention relates to the technical field of an ASON (Automatically Switched Optical Network) and provides a method and a system for carrying out service maintenance in the automatically switched optical network. When a certain section of optical fiber link needs to be maintained in the network, a network manager transmits a link maintenance command to nodes at both ends of the link; after the nodes receive the link maintenance command, a service on the link is inquired firstly; a first node of the service is positioned by a service label; the link maintenance command is transmitted to the first node; and the first node launches service maintenance. All the services on the link are maintained by transmitting the link maintenance command to different first nodes and automatically launching the maintenance command sequentially by each first node so as to avoid the complexity of the current link maintenance. When the network manager transmits the link maintenance command, all the service maintenance can be automatically completed. Therefore, the method and the system solve the bottleneck of the current batch service maintenance and improve the working efficiency.

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...
