Abstract
A wavelength-routed (WR) optical network using an Adaptive Burst Size (ABS) Optical Burst Switching (OBS) scheme is to be considered. The aim is to improve the offered QoS and offer distinctive Class-of-Service (CoS) separation for various network conditions in an adaptive way. Specifically, a hybrid triggering policy will be suggested to achieve the required network performance, such as average packet loss, average packet delay, and average network utilization, under both light and heavy traffic conditions. Performance results under dynamic and bursty traffic conditions will be presented and analyzed.
