This paper develops Load Balancing algorithms 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. This algorithm (RSNE - Reverse Subtree Neighborhood Exploration) performs at each iteration a basic change in the network by reconfiguring only a single entry in the routing table of a single node. This paper studies the performance of this algorithm in realistic networks under static and dynamic traffic scenarios. Simulation results show a rapid reduction of the congestion for static networks. The performance of the incremental scheme while tracking a changing traffic matrix is comparable to that obtainable through the complete re-optimization of the traffic.
