| 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... |
