The Effect of Burst Assembly on Performance of Optical Burst Switched Networks

Abstract

We evaluate and compare the performance of timer-based and threshold-based assembly algorithms in Optical Burst Switching networks. Results including burst blocking probability, mean packet delay and link utilization at the ingress node are presented from both simulations and two theoretical models. The results are obtained for the full range of input traffic load so they can provide guidelines for design and dimensioning links to meet desired Quality of Service levels.
