A benchmark implementation for evaluating the performance of power-aware routing algorithms in practical Software-Defined Networks

Abstract

The increase in demand for high network bandwidth has significantly increased the network power consumption and hence, capital expenditure and operational expenditure costs. Service providers are investigating various approaches to reduce operational and management costs, while delivering richer services across their networks. Recently, several centralized power-aware routing heuristic algorithms have been proposed leveraging the centralized control of the Software Defined Networking (SDN) architecture. However, a base solution for benchmarking the performance of these algorithms has not been developed yet. In this paper we propose an implementation of the centralized power-aware routing problem for SDN in GAMS. This implementation facilitates solving the problem using commercial packages and hence serves as a benchmark for accessing the performance of centralized power-aware routing algorithms. Experimental results demonstrate the efficiency of the developed implementation.
