Study on reduction of total bandwidth requirement by traffic dispersion

This paper studies the effect of using traffic dispersion in call admission control (CAC) on the reduction of the total effective bandwidth requirement for high-speed networks. In this paper, we consider a discrete-time queueing system and a particular source model which is called generalized binary Markov source (GBMS). We then focus on the effective bandwidth of GBMS. We provide some numerical results to investigate the effect of traffic dispersion on the total bandwidth requirement. The numerical results show that traffic dispersion is useful to reduce the total effective bandwidth required by GBMS.
