Real-time VBR traffic management in satellite-based ATM networks

Abstract

The design of effective traffic and resource management policies is a key issue in the deployment of ATM-satellite systems. This paper proposes a technique of call admission control and dynamic resource management to support ATM traffic classes in satellite environments. The effectiveness of the strategy is assessed by referring to a multimedia satellite platform, based on Ka-band payload and on-board processing, called EuroSkyWay. The main advantage is the effective exploitation of the satellite bandwidth by means of the statistical multiplexing of traffic sources and the guarantee of QoS provisioning to both real-time and non-real-time, constant and variable bit rate sources.
