This paper presents heuristic algorithms that may be used for light-path routing and wavelength assignment in optical WDM networks under dynamically varying trafยฎc conditions. We consider both the situations where the wavelength continuity constraint is enforced or not enforced along a light-path. T
There are two steps to set-up a multicast connection in all optical wavelength division multiplexing (WDM) networks: routing and wavelength assignment. Multicast routing is to ยฎnd a tree in the network rooted from a source node and connecting all destination nodes. Wavelength assignment is to assign
