Service Differentiation in Optical Burst Switching Networks

Abstract

In this paper, we give an overview and classification of optical burst switching schemes and burst reservation concepts. We compare the performance of different burst reservation mechanisms for an OBS node that does not distinguish different classes. The one that performed best and allows service differentiation, called Just-Enough-Time, is then evaluated by simulations and an approximative analysis for a two-class OBS node. A variety of new results show the pros and cons of the evaluated reservation mechanism with respect to service differentiation.
