Performance analysis of optical composite burst switching

In this letter, we introduce a queueing model to study the performance enhancement in a so-called optical composite burst switching network (OCBS). Based on our model, we develop a simple analytical method to calculate the packet loss probability and we provide numerical results to compare the performance of OCBS versus the traditional optical burst switching (OBS) technique. We then provide explanations for the performance improvement of OCBS over that of OBS.
