Performance evaluation of time driven switching for flexible bandwidth provisioning in WDM networks

This work further studies blocking issues that are related to time driven switching (TDS). TDS is a novel and promising technology for the realization of low complexity and high scalability switches in the electrical and optical switching domains. TDS is unique in enabling the implementation of all-optical fractional wavelength switching with current state-of-the-art components. Furthermore, TDS provides deterministic QoS guarantees for all streaming media applications. Being a new technology, TDS requires investigation, especially regarding its performance and efficiency. The performance in this paper considers multiple scenarios with variety of optical transmission and switch parameters. The performance results show that blocking does not compromise the efficiency in most cases, even with elevated offered traffic load with the restrictive scheduling of immediate forwarding.
