Abstract
In this paper, we propose a new threshold-based mixed-assembly technique with QoS support in optical burst switched networks. The most striking characteristic of the mixed-assembly policy is that both the low and high packet classes are aggregated into one burst simultaneously. Once contention occurs, there will be an overlap between the tail of the earlier arriving burst and the head of the contending burst. Combing with burst segmentation technique, we drop the tail of the earlier arriving burst that is mainly made up of low priority packets, thus the packet loss probability of the high packet classes will be guaranteed. Simulation results show that the proposed burst assembly scheme performs well in terms of performance metrics such as the average packet loss probability and the packet loss probability of the high class of traffic.
