The SFM is featured with Burst Segmentation and Prioritized Feedback (BSPF) that are used to provide quality of service (QoS) and realize high throughput and faster switching in the optical burst switched networks. Simulation and performance analyses show that the SFM effectively avoid collision in optical burst switching (OBS). Long delay time of deflection routing and immature technology of wavelength converter and optical buffer are not employed in the SFM. The SFM not only realizes quick switching but also allows preemption for higher priority bursts.展开更多

This paper introduces two novel backbone node structures for IP over WDM networks. These node structures can be used as improvement approaches to DPDP (default path and dedicated path) method. The flow classifiers, which are the main components of these node structures, and the performance metrics of these structures, are also discussed.展开更多
