LE-MRC: Low-energy based multiple routing configurations for fast failure recovery

Abstract

Fast failure recovery is an important issue in large-scale communication networks because the performance of data transmission is degraded for a long time when the failure occurs. Moreover, the energy consumption has increased recently as the amount of traffic becomes large. In this paper, for realizing both the fast failure recovery and the low energy consumption, we propose a low-energy based multiple routing configurations (LE-MRC). LE-MRC can be utilized in several types of networks such as MPLS networks and SDN based networks. In LE-MRC, three new link sets are derived for the fast failure recovery and the low energy consumption. Then, link ports that are not needed for the fast failure recovery are turned off for the low energy consumption. We evaluate the performance of LE-MRC in some network topologies with simulation. We also evaluate with ns-3 how the performance of data transmission are changed by using LE-MRC. In numerical examples, we show that the fast failure recovery and low energy consumption can be realized by using LE-MRC.
