In large optical networks, it is important to establish a connection from source node to destination node. In the centralized network management systems, the dynamical routing information and the states messages for failure have to be shared by the “flood” mechanism in the whole networks. Obviously, this scheme is a serious concern because the considerable “flood” packets will jam into the network. The paper tries to introduce ant colony algorithm to improve the fault recovery for routing problem. The algorithm is applied into routing computation platform for searching and recovery the impaired routes. The application of mobile agents can be as the communication entities between the management plane and data plane. They offer several benefits, such as alarms indication for failures, the refreshment of the pheromone level. Finally, full experimental data show that the fast convergence of routing information can be realized by using the proposed distributed scheme in the scene based on our routing tested.
