Guaranteeing Statistical QoS to Regulated Traffic: The Single Node Case

Free registration required

Executive Summary

Multimedia traffic can typically tolerate some loss but has rigid delay constraints. A natural QoS requirement for a multimedia connection is a prescribed bound on the fraction of traffic that exceeds an end - to - end delay limit. This paper proposes and analyzes a traffic management scheme which guarantees QoS to multimedia traffic while simultaneously allowing for a large connection - carrying capacity. This paper studies the traffic management scheme in the context of a single node. In order for the node to guarantee QoS, each connection's traffic is regulated. In order to support many connections, the link statistically multiplexes the connections traffic.
