Presents a method to establish real-time connections with guaranteed quality-of-services, based on per-session (/spl sigma/,/spl rho/)-characterization. Under two distinctive service disciplines, rate proportional processor sharing and fixed rate processor sharing, the authors derive tighter probabilistic bounds on per-session end-to-end overage cell loss rate, which is caused by either buffer overflow in the route or excessive delay at the destination. One remarkable feature of the bounding solutions is that they are solely determined by the probabilistic (/spl sigma/,/spl rho/) characterization of each session itself, independent of the network environment and other connections. To improve network resource utilization, the method is extended to allow statistical sharing of buffer resources at each node. The admission control scheme presented in the paper has a great flexibility in connection management since both bandwidth and buffer resources can be adaptively allocated among incoming and existing sessions according to present network resource availability. The (/spl sigma/,/spl rho/)-characterization strongly depends on traffic characteristics. The study of real multimedia traffic streams reveals the interrelationship among (/spl sigma/,/spl rho/)-characterization, traffic statistics and QOS constraint and also provides many engineering aspects of (/spl sigma/,/spl rho/)-characterization for connection management.
