Liang, WeifaVishwanath, Arun2015-12-132015-12-13September0780385497http://hdl.handle.net/1885/82800This paper considers the problem of establishing multiple multicast sessions in a multi-hop optical wavelength division multiplexing (WDM) network simultaneously, such that the sum of the cost of realizing these sessions is minimized and at the same time, the end-to-end delay between each source-destination pair is bounded. The cost of a multicast session is expressed in terms of the cost of using a wavelength on a link and the cost of wavelength conversion at a node. The end-to-end delay is bounded by the sum of communication delays on links and the wavelength conversion delays at intermediate nodes. In this paper, we present a solution to the problem by formulating it into an Integer Linear Program (ILP) and solving the ILP on a representative sized mesh network.Keywords: Algorithms; Bandwidth; Constraint theory; Integer programming; Light transmission; Linear programming; Optical communication; Optimization; Probability; Quality of service; Telecommunication traffic; Trees (mathematics); Wavelength division multiplexing;20042015-12-11
