Paper Abstract

With the increase of the Internet service, it is more and more important to provide better performance and quality in the WDM network. The paper introduces a novel dynamic routing (DR) algorithm based on OSPF with the balance parameter. Due to the limitation to the wavelength continuity, the problem of the routing and wavelength assignment (RWA) is also analyzed comprehensively. In designing the algorithm, RWA is considered, too. The protocol of OSPF may collect the network state information by flooding in WDM network. Furthermore, the algorithm can adapt to the traffic changes with rather little changes in transport performance and blocking probability. In order to prove the method efficient and robust, the simulation with two topologies is done and results are also analyzed and compared. At last, the conclusion and further work are given, too.
