Performance study of end-to-end resource management in ATM geostationary satellite networks with on-board processing

Because of their large geographic coverage, inherent broadcast capabilities, and fast deployment features, network operators plan to use satellite-based networks to supplement existing wire-line and legacy networks to bring broadband and multimedia services to endusers. Satellites are multiple access systems with very limited transmission capacity compared to terrestrial network nodes. Therefore, end-to-end resource management for such systems is key to deliver acceptable Quality of Service (QoS) to services while providing adequate efficiency. We study in some details, using simulations, a method integrating Bandwidth on Demand with Call Admission Control in geostationary satellite networks with an on board switch. In particular, we describe a set of algorithms and study the impact of different types of bandwidth reservation on the QoS received by the connections and the network efficiency.
