  • To address the problem that TCP performance degrades significantly on the Satellite communication networks, a new transport control protocol, TP-Satellite is introduced. In order to increase the Congestion Window (cwnd) rapidly at the beginning of data transmission, the traditional Slow Start strategy is replaced by a new strategy, named as Super Start. In order to decouple congestion decision from errors, a new scheme, which is based on two class priority IP packets alternately sending, is included in TP-Satellite. Bandwidth asymmetry problem is addressed by adoption of a ACK periodically sending strategy. Theoretical analyses and simulations indicate that TP-Satellite can increase the sending rate rapidly, discriminate the reason of packet loss effectively, enhance throughput performance significantly, and reduce the bandwidth used in the reverse path sharply.
