INTELLIGENT CONTROL METHOD, APPARATUS AND SYSTEM FOR OPTICAL NETWORK

WIPO Patent Application WO/2023/015897

A1

The present application relates to an intelligent control method, apparatus and system for an optical network. The method comprises: a controller analyzes network survivability on the basis of whole network topology information and service connection information, obtains and issues survival data to an ASON control plane node for storage; when a network link failure occurs, a source node of a failed service in the ASON control plane node establishes rerouting connection to failed links according to the survival data, and reports a rerouting connection establishment result to the controller; and the controller updates a failed service recovery state according to the rerouting connection establishment result, performs re-optimization calculation on the failed link that fails to recover to obtain a new rerouting connection path, and sends the new rerouting connection path to the source node of the failed service so as to perform service recovery on the failed link that fails to recover. In the present invention, centralized control of the controller is combined with a distributed control technique of the ASON control plane node, so that the survivability of an optical network is effectively improved.
