Paper Abstract

Crankback is an effective method to enhance the connectivity in the control plane of ASON. By introducing crankback and computing a new route, connection that hasn't sufficient resource along the origin route can be re-established along a new route. In existing crankback mechanism, A PATH ERROR message has to be sent back to the source node in the case of resource insufficient and the source node undertakes the rerouting job. With this mechanism the connectivity is improved, but the connection establishing time is prolonged. A crankback mechanism based on local node rerouting is proposed. The simulation shows that the local node rerouting crankback mechanism gains a smaller connection establishing time than that of the source node rerouting one.
