SERVICE MAINTENANCE METHOD AND SYSTEM IN AN INTELLIGENT OPTICAL NETWORK

摘要

The present invention relates to the ASON technical field, and provides a method and system for service maintenance in an intelligent optical network. When a certain section of optical fiber link is needed to be maintained in the network, a network management issues a link maintenance command to nodes at both ends of the link; after receiving the link maintenance command, the node firstly inquires services on the link, locates head nodes of the services through service tags, and transmits the link maintenance command to different head nodes; and the head nodes initiate the service maintenance. By transmitting the link maintenance command to different head nodes, the various head nodes automatically initiate the maintenance command in turn, and thereby all services on the link are maintained, the complexity of the current link maintenance is avoided, and the maintenance of all the services can be completed automatically by way of only needing the network management to issue the link maintenance command, which solves one bottleneck of the current batch service maintenance and improves the work efficiency.
