Abstract: All-optical networks based on wavelength division multiplexing (WDM) have emerged as a promising technology for network operators to respond to an increased demand for broadband service. All-optical networks consist of optical fiber links and nodes. Each node has a dynamically configurable optical switch or router, which supports wavelength based switching or routing. Configuring these optical devices across the network enables one to establish all-optical connections, or lightpaths, between source and destination nodes. In order to establish a lightpath, the network needs to decide on the route and the wavelength(s) for the lightpath. Given a set of connections, the problem of setting up lightpaths by routing and assigning a wavelength to each connection is called the Routing and Wavelength Allocation (RWA) problem. There are two variations of the problem: static and dynamic. In the static case the set of desired connections is known beforehand; in the dynamic case the conne...
