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-bas ed networks to supplement existing wire-line and legacy networks to bring b roadband and multimedia services to end-users. Satellites are multiple acce ss systems with limited transmission capacity compared to terrestrial netwo rk 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. Using simulations, we study in some detail a method integrating Bandwidth o n Demand with Call Admission Control in geostationary satellite networks wi th an on-board switch. In particular, we describe a set of algorithms and s tudy the impact of different types of bandwidth reservation on the QoS rece ived by the connections and on the network efficiency.
