Performance Evaluation of Photonic Networks Under Dynamic Traffic Conditions

This paper focuses on two aspects of photonic network traffic performance investigation. Two different modelling approaches for the evaluation of network nodes under dynamic traffic conditions are described. This allows to evaluate how suitable different node architectures are for networks carrying dynamic traffic. Furthermore, routing strategies are becoming more important with increasing dynamic. A lot of work reported in literature deals with “wavelength routing”. In most cases however, this means static wavelength assignment to routes and not dynamical routing of random wavelength path requests. This paper now considers dynamic traffic aspects of wavelength routing where many analogies to classical routing strategies can be observed. Therefore, a short overview of routing methods is given before we describe our modelling approach and present some case studies and results.
