<p>A method for coordinating automatic switched optical network link resource comprises: link resource management part of network unit of service transmitting or receiving side acquires the status of channel occupy and link coordinating strategy from the corresponding link resource database according to the resource coordinating request of link, and transfers the service of coordinated channel to the corresponding target channel according to the coordinating strategy; link resource management part of service transmitting side transmits service on the coordinated channel and the target channel at the same time, and ends the service transmission of the coordinated channel until it determines that link resource management part of receiving side is switched to the target channel by changing information. The present invention realizes resource coordinating of the whole network link by combined transmitting service at service transmitting side and realizing switching at the service receiving side later, under the condition of non-damnification service, and by stepwise coordinating the free resource. The present invention has advantage that the present invention is simple and reliable.</p> |
