Controlled load services in IP QoS geostationary satellite networks

Abstract

In this paper a multimedia satellite platform called EuroSkyWay and the IntServ Controlled Load Services (CLS) have been considered. The behavior of the system loaded with Controlled Load (CLS) traffic and Guaranteed (GS) traffic has been evaluated. The management of CLS is important in order to manage the category the traffic called "better than best-effort" and to guarantee a full interoperation with the terrestrial network. In particular, Call Admission Control phase for CLS in the satellite network has been studied. Different simulations have been outlined and the conformance to QoS parameters for the approaches have been verified. Furthermore, the satellite utilization and the average end-to-end delay bound for different values of bandwidth levels declared in satellite admission phase have been evaluated. © Springer-Verlag 2004.
