| dc.description.abstract | Satellite communications are becoming increasingly important due to the geographical reach of satellite transmissions and high bandwidth requirements. Bi-directional satellite links often comprise a forward and a reverse space link that are asymmetric in bandwidth. The forward space link has high bandwidth and high delay, while the reverse link has limited bandwidth and high delay. Throughput optimization is required in order to utilize the high bandwidth space link effectively to support interactive services. In addition, the asymmetric nature of the space links would require different flow control and routing strategies compared with existing networks. The importance of QoS (Quality of Services) over satellite link is the main focus of this research, which addresses how mitigated protocols and QoS mechanisms can be used to optimize satellite link throughput for TCPIIP streams. A model of the TCPIIP stack over Asymmetrical Geostationary Satellite Links has been developed to evaluate support of prioritized and non-prioritized TCP traffic over the satellite link. Traffic prioritization is needed to provide end-to-end terrestrial and sateIlitebased networks. Various parameters, such as router buffer size, TCP window size and performance of Random Early Detection with In and Out (RIO) over the satellite link is examined | en_US |
