Abstract

We propose a preemptive scheme based on the hop number of a burst for optical burst switching (OBS) networks. In the proposed scheme, when a burst fails in reserving a wavelength at its last hop, the burst can preempt another burst transmission. We consider a tandem network with four OBS nodes and analyze the burst loss probability for the proposed scheme with a continuous-time Markov chain. We also evaluate by simulation the performance of our proposed scheme for a unidirectional ring network. Numerical examples show that our proposed method effectively decreases the loss probability of the burst with a large number of hops.
