MatPlanWDM v0.5

Educational network planning tool for the RWA problem in WDM networks (MILP and heuristic based)

MatPlanWDM is a network planning tool for wavelength-routing WDM networks. The input parameters to the planning problem are the network physical topology, the traffic matrix, and technological constraints like the number of transmitters, receivers, optical converters and wavelengths available. It includes a set of heuristic algorithms for solving the virtual topology design, and the routing and grooming of traffic flows on top of it. The set of heuristic algorithms can be extended. This is eased by a set of libraries of classical network optimization algorithms included in the tool. In addition, an implementation of the linear mixed-integer programming (MILP) problem to obtain the optimal solution is also included. A what-if analysis GUI allows the design of exhaustive tests. A multi-hour analysis GUI supports the evaluation of dynamic planning algorithms which react to traffic matrixes that vary each hour of the day. This is useful for the planning of intercontinental topologies that span multiple timezones, where node activity is affected by its local time. A dynamic planning GUI allows testing generic dynamic algorithms which react to flow arrivals and departures.
