Abstract :
A collection of slides from the authorpsilas seminar presentation is given. In this paper we propose: a mathematical model for the global design problem of WDM networks including the traffic grooming. This problem consists in: finding the number of fibers between each pair of nodes (i.e., the physical topology); finding the number of transponders to install at each node; choosing the set of lightpaths (i.e., the virtual topology); routing these lightpaths over the physical topology; grooming and routing the traffic over the lightpaths. A heuristic algorithm to find "good" feasible solutions. Finally, numerical results are presented and analyzed.
