Abstract

In WDM networks, when a session request is received by the network, the problem of establishing light-paths by routing and assigning a wavelength to this connection session is called the Routing and Wavelength Assignment (RWA) problem. The selection of routing algorithm and wavelength assignment method is the key point to solve this problem. And the flooding technique is always used for those routing algorithms to get the resource status and topology information. In this paper, we propose a novel routing algorithm, Rank Total wavelengths and Available wavelengths (RTAW), which dramatically reduces the flooding frequency while guaranteeing a low blocking rate. Compared with other algorithms, the simulations results prove the benefits of this algorithm.
