| Abstract | TCP or the Transmission Control Protocol provides reliable delivery of data across any network path, which includes terrestrial and satellite network. However on satellite networks, due to large propagation delay, the behavior of TCP is affected and the performance may face problem. The intention of this research is to study how do different kinds of TCP congestion avoidance algorithms behave on the satellite link. For easier understanding, the case of TCP over terrestrial network is first discussed. Their performance is evaluated in order to obtain the most suitable congestion avoidance algorithm for satellite link. The evaluation includes TCP efficiency, average throughput, and mean queuing delay. In the case of TCP over satellite network, the TCP window size is also varied in order to observe each TCP congestion avoidance algorithm with varying window size. This window allows the receiving TCP to control how much data is being sent to it at any given time. We also observe how each TCP congestion avoidance algorithm reacts to the window that have the size exceeding the standard TCP window size. This research mainly focuses on the use of selective acknowledgments (SACK) and selective repeat to TCP. Simulations are used in order to observe how does the use of SACK improve TCP performance when compare to other types of TCP congestion avoidance algorithm, which includes Tahoe, Reno, and New-Reno. Results reveal that SACK really outperforms the other congestion avoidance schemes |
