• TCP performance drastically decreases over satellite links due to long delays and high bit errors. We introduce a new congestion control mechanism, TCP-Cherry proposed by Utsumi et al., to improve TCP performance over satellite IP networks. The major feature of TCP-Cherry is the probing of network for available resources using low priority supplement segment. Like data segments, supplement segments also carry data that has not yet been transmitted. Supplement segments are used in two new algorithms, Fast-forward Start and First-Aid Recovery. Finally, simulation results show that the proposed TCP-Cherry yields upto a maximam improvement of more than 150% in goodput compared with existing schemes.
