A Heuristic Algorithm for Designing Logical Topologies in Packet Networks with Wavelength Routing

By introducing optical telecommunication networks with WDM (Wavelength Division Multiplexing), the capacity of network becomes very high and the price more acceptable then those with pure electronic processing. Major part of traffic in these networks is going to be IP, a packet switched traffic. On the other hand, contemporary optical networks are basically circuit switched. A promising solution for interfacing different network levels is a logical topology for IP that is transported over wavelength path established in WDM network. Optimal design of such logical topology has been the goal of many algorithms. In this paper a new heuristic algorithm, LLHS (Low Traffic Largest Hops High Traffic Smallest Hops) is proposed to design optimal logical topology aimed at minimizing packet congestion.
