A Markov model for the design of feedback techniques to match traffic specification parameters in MPEG video sources

Abstract

Guaranteeing of quality-of-service (QoS) is a challenging task to promote the evolution of the Internet from a simple data network into a true multiservice network. To this end, the IETF intserv Working Group, with the goal of defining a next generation Internet, has defined two QoS classes: Guaranteed Services and Controlled-Load Services. For both of them the source is required to declare its traffic characteristics by means of a number of Tspec parameters and guarantee these traffic characteristics during transmission. The target of this paper is to develop an analytical tool for the design of feedback laws which allow MPEG encoders to inject into the network video traffic shaped according to the declared Tspec, while maintaining an acceptable perceived quality. © Springer-Verlag Berlin Heidelberg 2001.
