Asymptotic Delay Distribution and Burst Size Impact on a Network Node Driven by Self-similar Traffic
It was shown recently that under self-similar traffic the delay distribution
function can decrease very slowly, so in order to guaranty the Quality of
Service (QoS) in communication networks, burst size is usually bounded by some
value using, for example, leaky-bucket mechanism. In this paper we consider a
discrete-time queue with M types of independent input processes. Each
input process is the aggregation of sessions (bursts) arrived by a Poisson
process. Asymptotic delay distribution at network node driven by self-similar
traffic and its effects on burst size bound have been analysed. It is also found
the critical value of the burst size at which delays start to increase
considerably.
