This book focuses on the performance evaluation of the Optical Burst Switched (OBS) networks. A simulation framework based on OPNET Modeler is designed and implemented to evaluate the performance of an OBS network in the presence of self-similar traffic sources. The impact of self-similar traffic sources and specific design parameters imposed on the network is assessed in terms of burst assembly delay, its jitter and burst loss ratio. The performance metrics have a strong dependency on parameters such as number of packets per burst, assembly timeout, number of available wavelengths and the degree of the traffic self-similarity. Furthermore, the impact of time and size-based burst assembly algorithms utilized in edge routers, on the self-similarity level of the output traffic, is evaluated. Both static & adaptive approaches are examined. This research utilizes the OPNET Modeler® focusing on the characteristics of the output traffic. Various Hurst parameter estimators have been applied...
