Research Abstract

In this work, we construct the network that achieves the robustness against environmental changes with a small energy consumption. In this work, we construct a logical network over the physical network. We first propose a method to control a logical network so as to achieve the robustness against environmental changes by adding only a small number of logical paths. Then, we also propose a physical network structure focusing on the network on chip. In this network structure, we accommodate the traffic demands with a small energy consumption by using circuit switches efficiently.
