This paper new load balancing techniques are proposed based on IP-like routing, where the forwarding mechanism is only driven by the destination address. The aim of this work is to consider the applicability of this approach in the context of optical networks. The proposed algorithm (RSNE - Reverse Subtree Neighborhood Ex-ploration) implements a local search technique where the basic step is the modification of a single entry in the routing table of a node. A randomized method with reduced computational complexity (fRSNE - fast RSNE) is also presented and analyzed. Both schemes allow an incremental implementation where local search steps are continuously performed as traffic conditions change.
