Abstract

This paper presents an analytical model to calculate the send rate of TCP sources as a function of the main design parameters of optical burst-switched (OBS) networks. The novelty of the work is the possibility to deal with generic source speed that was previously evaluated only by simulation. The pretty good accuracy of the model is proved by comparisons with simulation results. The practical significance of the model is shown by an application example where burst loss is consequence of contention in OBS core nodes.
