In this paper, the authors present the study and analysis of performance offered by TCP protocol variants over geo-satellite link. The long delay-bandwidth characteristic of satellite network has big impact on TCP performance and it doesn't fulfill the criteria for given QoS. The drawbacks of TCP may be mitigated in satellite environment by properly tuning some of the TCP parameters. This paper is to study different variants of TCP protocol in satellite environment and propose modifications to enhance its performance over satellite link. At this time, all mitigations discussed in this paper are IETF standards track mechanisms (or are compliant with IETF standards) along with some suggestions by researchers.
