TCP congestion window tuning for satellite communication using cross-layer approach

摘要

In this paper, we propose a TCP congestion window (CWND) tuning scheme which considers the resource allocation information of satellite link and the number of sessions. The proposed scheme sets TCP congestion window size by using satellite resource allocation information exchanged between TCP and the link layer and the number of session. To evaluate the performance, we implemented the proposed scheme on TCP Linux kernel over TCP-splitting based performance enhancing proxy (PEP) test-bed. The results show that the performance of proposed protocol better than existing TCP protocols, both in single and multiple sessions in variant bit error rates (BER) notably in higher BER.
