Abstract

Optical burst switching (OBS) has increasingly received attention as a potentially bandwidth-efficient approach to support an all-optical Internet for the ever-growing broadband traffic. In this paper, the authors address how to provide efficient end-to-end quality-of-service guarantees in OBS networks. Proactive wavelength pre-emption is proposed in order to achieve the upper bound on end-to-end burst loss probability for guaranteed traffic. Their simulation results show that the proposed algorithm is an effective solution for providing incessantly end-to-end loss guarantee for mission-critical applications
