| Abstract(in English) | When the links the WDM (Wavelength Division Multiplexing) network fail in the networks, the damage due to loss of information being delivered through the links becomes much higher than that in the usual networks. To reduce the damage as much as possible, an fault tolerant technique called redundant path designs is introduced. In these designs, backup paths between source and destination nodes, such that when the primary paths between them fail the primary paths are quickly switched to the backup paths, are prepared. In the previous research, the redundant path designs are done by the centralized approach. However, it takes exponential times to compute the smallest number of wavelengths in the network as the size of the network becomes large. This paper, therefore, formulates the two problems for the multiagent-based redundant path designs called VWP and WP and proposes a method for respective problem, which drastically decreases the computation time for obtaining the paths with the smallest number of the wavelengths. The experimental evaluation on the optimality of the proposed method for VWP shows the effectiveness of the proposed method. |
