| Abstract | The broadband multimedia satellite system has the capability to offer high-speed access to multimedia applications. The characteristic of this system depends on the orbital types LEO, MEO and GEO. The integration of broadband multimedia satellite system with the terrestrial core network can provide a wide range of IP-based application with QoS guaranteed to satellite link. In this research, the proposed broadband multimedia satellite system and the performance of IP QoS over IP satellite-terrestrial network are studied. The parameters of the proposed satellite system Sky Bridge, ICO and IPST AR are used for studying the proposed satellite system. The roundtrip propagation delay, the visible satellite, the satellite availability, the satellite handover and the coverage area are the studied cases of these systems. To study the performance of IP QoS, the satellite access network is modeled as IntServ Guaranteed Service model connected to DiffServ terrestrial network. A source is connected to the satellite terminal and generates VBR traffic through satellite link to the destination connected to the terrestrial network. The VBR traffic is generated using the ON-OFF source model. The RSVP token bucket operation is used to regulate the VBR traffic and provide QoS before transmitting over the satellite link. The bandwidth of the satellite link can be allocated by the receiver using the IntServ concept. Then, the bandwidth utilization of permanent and semi-permanent connection is evaluated over the satellite link. The studies of satellite systems show that LEO system has the lowest and varied roundtrip propagation delay. However, LEO has a high number of satellite handovers/call and a low coverage area. Finally, the IP perfo1mance evaluation demonstrates that semipe1manent connection is an appropriate connection for satellite systems with the low altitude. As it required the lower given bandwidth close to the given bandwidth in permanent connection but still provide good utilization. |
