In today’s WDM networks, the dominant cost component is the cost of electronics, which is largely determined by how traffic is groomed at each node. Therefore, the issue of traffic grooming is extremely important in the design of a WDM network. In this article, our goal is to introduce various aspects of the traffic grooming problem to the reader. We start with the static traffic grooming problem...
In this chapter, we present a new scheme for traffic grooming in WDM mesh networks. We propose a new node architecture which brings together all the three qualities desired: practical feasibility, cost-effectiveness and efficient grooming capability. None of the models considered so far in the literature have managed to satisfy all three criteria. We achieve these three ideals by considering a combination...
