Abstract

Time-slotted optical burst switched network is a new paradigm to support IP over WDM by combining Time Division Multiplexing and Optical Burst switching technology. This paper presents the features of time-slotted optical burst switched network and addresses the related routing, wavelength and time slot assignment techniques to avoid contentions in the network. Cooperated with fiber selection algorithms, the proposed dynamic load balancing routing techniques use shortest path algorithm based on multi-wavelength virtual topologies to avoid congestion for burst requests. Simulation results show that the proposed load balancing routing techniques improve the wavelength utilization and reduce the burst loss rate.
