Optical burst switching (OBS) has emerged as a new paradigm to exploit the benefit of transparent optical switching while achieving efficient statistical multiplexing at the burst lever. In this paper, we address how to provide efficient end-to-end QoS guarantees in OBS networks. Proactive wavelength-preemption (PW) is proposed in order to achieve upper bound on end-to-end burst loss probability for guaranteed traffic. Our simulation results show that the proposed algorithm is the effective solution to provide absolute QoS for WDM OBS networks
