<b>Abstract:<p align=\"justify\"> <br /> Satellite communications continue to play important role in business comnnunication networks. The demand for Internet bandwidth has been growing rapidly, and the use of satellite is one possible solution for broadband Internet access. However, long delay and high error rate satellite channels suffer poor throughput using standard Transmission Control Protocol. Several changes have been proposed that could help TCP performance over high-speed long delay paths. This study was to investigate the performance of several TCP variants (Reno, New Reno, and SACK), and TCP Large Window option over Geostationary Earth Orbit (GEO) satellite. Simulation result shows that implementation of SACK TCP and Large Window option improves on utilization of the satellite link as long as packet error rate is low. Another results were: under a bottleneck link, TCP New Reno is the most \"fair\" while TCP -SACK is the least but it has the highest utilization. In a hybrid network, low fairness index could be improved by making the TCP sender with long RTT connection slightly more aggressive.<p align=\"justify\">
