Abstract: In this paper we propose an adaptive routing strategy, called Weighted Link Capacity (WLC), as a candidate solution for the routing problem. The WLC algorithm consists on choosing the path that minimizes the cost of network resources, whilst, in parallel, maintaining the network traffic as balanced as possible. Its strategy is based on the number of hops, link length and free link capacity. We assume two constraints to block a connection: first, when there is no free path available; second, when the distance of the path exceeds the optical transmission reach of optical equipments without 3R regeneration, which results in a bit error rate above an acceptable limit (e.g., 10-12). The simulation results of dynamic traffic in two hypothetical meshed networks are shown in terms of blocking probability as a function of network load. We demonstrate that WLC outperforms the traditional routing algorithms. © Springer-Verlag 2004.
