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.
