Paper Abstract

In this paper, we propose a threshold-based burst assembly scheme in conjunction with a burst segmentation policy to provide QoS in optical burst switched (OBS) networks. Bursts are assembled at the network edge by collecting packets that have the same QoS requirements. Once the number of packets in a burst reaches a threshold value, the burst is sent into the network. We investigate various burst assembly strategies which differentiate bursts by utilizing different threshold values or assigning different burst priorities to bursts that contain packets with differing QoS requirements. The primary objective of this work is to find the optimal threshold values for varous classes of bursts. We show through simulation that there is an optimal value of burst threshold that minimizes packet loss for given network parameters.
