Study on reduction of total bandwidth requirement by traffic dispersion

Abstract

This paper studies the effect of traffic dispersion on the reduction of the total effective bandwidth requirement. 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.

Packet dispersion and the quality of voice over IP applications in IP networks

“…In this study, we model the application loss, regardless the source of the loss (network loss or network delay 6 ). Internet loss models have been studied in many studies, such as [3][4].…”

“…In CDMA radio networks, traffic dispersion (also called frequency-hopping) is used for security reasons and in order to statistically multiplex noises. In [6][23] traffic dispersion in IP networks is suggested to reduce traffic burstiness and therefore achieve higher resource utilization. Another idea, proposed in [12], suggests using traffic dispersion as a better method to Forward Error Correction (FEC) technique for voice over IP (VoIP) applications.…”
