Abstract

The technology employed in fiber optic communication which multiplexes a number of optical carrier signals onto a single optical fiber by using different wavelengths of laser light is known as the wavelength-division multiplexing (WDM). In optical WDM networks, 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 RWA methods, an adaptive routing and wavelength assignment protocol is proposed which is based on maximum flow and load balancing. In this work, Routing and Wavelength assignment is proposed adaptively based on the type of reservation request. When a network handles an advance reservation request, the routing is done using our Max-flow algorithm and wavelength assignment is done using an advance reservation algorithm. When the network handles an immediate reservation request, routing is done using the traffic load on each link on the paths and wavelength assignment is done using an immediate reservation algorithm.
