Optical network intelligent control method, device and system

Abstract

The invention relates to an optical network intelligent control method, device and system; the method comprises the steps: analyzing the network survivability through a controller based on whole network topology information and service connection information, and obtaining and issuing survival data to an ASON level control node for storage; when a network link fault occurs, establishing, by a source node of a fault service in the ASON level control node, a rerouting connection for a fault link according to the survival data, and reporting a rerouting connection establishment result to the controller; then updating, by the controller, a fault service recovery state according to the rerouting connection establishment result, and performing re-optimization calculation on a fault link which fails in recovery so as to obtain a new rerouting connection path; and sending the new rerouting connection path to the source node of the fault service so as to carry out service recovery on the fault link which fails in recovery. According to the invention, the centralized control of the controller is combined with the distributed control technology of the ASON control level nodes, so that the survivability of the optical network is effectively improved.

Description

technical field [0001] The invention relates to the technical field of optical communication, in particular to an optical network intelligent control method, device and system. Background technique [0002] The optical transport network controls the automatic protection and recovery of faulty services through an intelligent system to realize self-healing of network faults. In order to avoid the loss of bearer business traffic and ensure the quality of service, it is required that faulty services can be quickly protected and restored; usually optical network services include 1+1 protection and heavy-duty Routing Restoration Two basic protection restoration types: [0003] The 1+1 protection type service is realized by adopting the redundancy of the active and standby connection paths. When the working connection path fails, through the automatic protection switch (Automatic Protect Switch, APS) mechanism of the device, the service flow is quickly switched to the standby conne...
