Abstract

We consider a traffic model where a single source generates traffic having J (J⩾2) quality of service (QoS) classes, QoS in this case described by a cell loss probability objective εj for QoS class j. We assume that ε1⩾ε2 ⩾...⩾εJ, in other words, class J has the most stringent QoS requirements and class 1 the least. The traffic from K such independent heterogeneous Markov-modulated fluid sources is multiplexed into a single buffer of size B. There are J-1 thresholds {B j, 1⩽j⩽J-1} such that 0
