A link failure localization strategy based on knight''s tour for Mesh optical network
基于骑士巡游的Mesh光网络链路故障定位策略

The link failure localizing mechanism in the optical network should have the features of rapidness and low cost. Based on the method of knight s tour, a strategy for single link failure localizing is proposed in this paper. Firstly, the network topology is mapping with the form of chessboard touring by the knight. The nodes and links of network are mapped on a corresponding chessboard. Subsequently, the probing signals are used to detect the network status in real time manner. By looking for static mapping table, the single link failure is located according to feedback fault information. Simulation results show that the single link failure can be effectively located by knight s tour scheme with low cost in network resources.
