Paper Abstract

The problem of routing and wavelength assignment (RWA) in WDM (wavelength division multiplexing ) networks is addressed in this paper. Most of the attention has been devoted to RWA algorithm. In this article, some concepts on RWA are studied first. Then we studied the associated research problems and challenges on RWA. Various RWA approaches are examined and compared. Finally, we proposed a new RWA algorithm based on multi-objective. In this new algorithm, we consider multiple network optimizing objectives to setup a lightpath with maximize profit and shortest path under the limited resources. By comparing and analyzing, the proposed algorithm is much better than the algorithms, which only consider one optimizing objective. This new RWA algorithm may be useful to a network maker.
