Abstract

In this paper we develop a Load Balancing algorithm for IP-based Optical Networks. The considered networks are based on a routing protocol where the next hop at a given node depends only on the destination of the communication. Our algorithm (RSNE - Reverse Subtree Neighborhood Exploration) performs at each iteration a basic change of a single entry in a routing table in order to minimize the disruption of the network.We study the performance of our algorithm in realistic networks under static and dynamic traffic scenarios. Simulation results show a rapid reduction of the congestion for static networks and a performance of the incremental scheme while tracking a changing traffic matrix comparable to the complete reoptimization of the traffic.
