| Abstract(in English) | According to a rapid growth of the bandwidth capacity of the WDM network, traffic loss due to the failure of the network components is becoming unacceptable. Against this problem, protection preparing backup paths for the working paths is now considered to enhance the reliability of networks by high-speed recovery from the failure. In this paper, we introduce a notion of QoP (Quality of Protection), which is one realization of QoS suitable to the WDM network. We denote QoP as a processing time from the occurrence of the failure to the end of recovery time of paths. We propose a heuristic algorithm using layered graph to design a logical topology with satisfying each QoP requirement from node pairs. Our objective is to minimize the number of wavelengths on a fiber in the logical topology. We present the effectiveness of algorithm through our numerical evaluation. |
