Satellite transmissions have an important role in telephone communications, television broadcasting, computer communications, maritime navigation, and military command and control. Moreover, in many situations they may be the only possible communication set-up. Trends in telecommunications indicate that four major growth market/service areas are messaging and navigation services (wireless and satellite), mobility services (wireless and satellite), video delivery services (cable and satellite), and interactive multimedia services (fibre/cable, satellite). When using geostationary satellites (GEO), the long propagation delay may have great impact, given the end-to-end delay user’s requirements of relevant applications; moreover, atmospheric conditions may seriously affect data transmission. Since satellite bandwidth is a relatively scarce resource compared to the terrestrial one (e.g. in optical transport networks), and the environment is harsher, resource management of the radio segment plays an important role in the system’s efficiency and economy. The radio resource\ud management (RMM) entity is responsible for the utilization of the air interface resources, and covers power control, handover, admission control, congestion control, bandwidth allocation, and packet scheduling. RRM functions are crucial for the best possible utilization of the capacity. RRM functions can\ud be implemented in different ways, thus having an impact on the overall system efficiency. This tutorial aims to provide an overview of satellite transmission aspects at various OSI layers, with emphasis on the MAC layer; some cross-layer solutions for bandwidth allocation are also indicated. Far from being an exhaustive survey (mainly due to the extensive nature of the subject), it offers the readers an extensive bibliography, which could be used for further research on specific aspects

“…The information used to perform this estimation is the current state of the TCP Westwood congestion control window and Packet Error Probability statistics. The TCP Westwood related data is obtained from the transport layer which is assumed to use TCP Performance Enhancing Proxies at the edges of the satellite network and is used to emulate the evolution of the congestion window based on the calculation proposed in [14]. The latter is based on real time data on packets dropped from the network layer IP queues.…”

Abstract-Satellite communications can play an important role in extending the reach of broadband networks to terrestrially underserved areas. However, several popular internet applications could suffer from performance degradation over satellite (e.g. realtime gamming, web browsing, VoIP), thus necessitating protocol modifications and additional optimisation mechanisms. Cross-layer design, which is the optimisation technique adopted in this paper, is a relatively new idea in network design. It is based on blurred boundaries between network layers. In particular, two cross-layer mechanisms are described; the first adapts the VoIP speech coding rate according to network congestion while the second uses TCP state information at MAC layer in order to improve the throughput of TCP traffic. Analysis in this paper demonstrates that the use of cross-layer techniques could improve the performance of the targeted applications in terms of reduced delay while continuously maintaining an optimal speech coding rate for VoIP.
