Maximum Flow Based Load Balanced Routing Protocol for WDM Networks

In optical WDM networks, maximum flow represents the maximum amount of light-paths that can be set up for a given source-destination node pair. When maximum flow algorithms are used for the Routing and Wavelength Assignment (RWA) problem, it optimizes the network resource usage. The existing routing methods rarely consider the current network load when making the routing decision. In order to overcome the drawbacks of the existing routing methods, an efficient routing protocol is proposed based on maximum flow along with load balancing. For each source and destination pair, maximum flow paths are determined and among the determined max flow paths, the current traffic load of each path is calculated. The path with the minimum load is chosen as the best path.
