Paper Abstract

In this paper we present a new localized distributed routing approach, called Multi-Path routing, for real time provisioning in a WDM network. Under the proposed approach, no global state information exchange among network nodes is needed and the destination node makes adaptively both routing and wavelength selection decisions. Two path selection schemes are considered and their performance is compared, namely First-Come-First-Serve (FCFS) path selection scheme and least- congested path (LCP) selection scheme. Time discrete simulation tool is developed to analyze the blocking performance, the connection set up time and the bandwidth required for control messages. Results show that the new adaptive multi-path routing algorithm outperforms the conventional alternate shortest-path routing algorithm.
