Topological design of the wavelength-division optical network

The twofold purpose of this research is to develop mathematical programming tools for the optimal or near-optimal design of a new type of network architecture called the wavelength-division optical network (WON) and to discover underlying design principles for such networks via experimentation using these tools. The WON, a multichannel, multihop lightwave network with tunable transceivers, is suitable for use as a metropolitan area network. A unique feature of the WON is that a great number of virtual topologies can be mapped onto a given physical topology. The problems of virtual- and physical-topology design in the WON are described, techniques for their solution are presented, and the interplay between these problems is studied
