Résumé des résultats (Abstract) (Anglais)

During this project, several network planning and evaluation tools have been conceived and integrated into the CANPC (Computer Aided Network Planning Cockpit) framework, also developed in the Telecommunications laboratory (STI-ITOP-TCOM) of EPFL. Two main research directions have been considered: routing and wavelength assignment in tranparent WDM networks and planning of all-optical packet-switched photonic networks. In both fields some relevant contributions have been published and the work performed can be considered as a good starting point for further research topics. A complete planning of several topologies of a pan European photonic network has been performed. Different aspects of photonic networks from physical layer issues (amplification and regeneration), over switching mechanisms (circuit and packet switching), to network planning (logical topology design, traffic grooming, protection and restoration mechanisms) have been addressed. Several routing and wavelength assignment techniques for optical circuit switched networks have been evaluated and compared in terms of network cost and efficiency. Optical packet switched networks were studied from the planning, simulation and performance evaluation perspective. A network planning procedure with the cell loss ratio calculation relies on an analytical procedure has been developed. Simulation issues addressed the performance evaluation of fibre delay lines based buffers with Poisson and self-similar input traffic.
