Abstract

In this paper we propose a new scheme Statistical Expedited Forwarding to support a new class of service that guarantees bounded delay and bounded packet loss performance. The goal of the proposed scheme is to provide the Integrated Services type of performance guarantees, but without maintaining per-flow state in the network core. The target applications are both delay-sensitive and loss-sensitive like IP telephony, video applications and emerging on-line electronic business-related applications. In order to guarantee delay and loss bounds, the effective resource (consisting of bandwidth and buffer) is assigned to each class according to the given QoS requirement. In addition, we further study the fairness among flows in a class. The experiments on several voice and video applications show the strength of the proposed scheme.
