| Abstract(in English) | According to rapid increase of the Internet traffic, its total power consumption also increases. Therefore, it is necessary to decrease the total power consumption. Lightpath networks attract attention because they can relief the increase of the total power consumption by bypassing IP routers. Light trail networks have been proposed as an extended network architecture of lightpath networks. Light trail networks can achieve higher throughput than lightpath networks, and it is expected that light trail networks also show higher power efficiency than lightpath networks. In this research, we evaluate the power efficiency of light trail networks. In the evaluation, we reduce a power-efficient routing and wavelength assignment problem to a shortest path problem on an auxiliary graph, and solve it. In order to achieve this, we modify the conventional auxiliary graph for lightpath networks so that it can reflect the communication method of light trail networks. In addition, we calculate link costs of the auxiliary graph so that they corresponds to the increase of the total power consumption caused by the accommodation of traffic demands. Simulation results show that 1) light trail networks show higher power efficiency only when the network load is low and when the bandwidth granularity of communication channels is coarse, and 2) light trail networks show higher blocking probability than lightpath networks when they aim at minimizing the total power consumption. |
