Network Coded TCP (CTCP) Performance over Satellite Networks
The authors show preliminary results for the performance of network Coded TCP (CTCP) over large latency networks. While CTCP performs very well in networks with relatively short RT T, the slow-start mechanism currently employed does not adequately fill the available bandwidth when the RT T is large. Regardless, they show that CTCP still outperforms current TCP variants (i.e., Cubic TCP and Hybla TCP) for high packet loss rates (e.g., > 2.5%). They then explore the possibility of a modified congestion control mechanism based off of H-TCP that opens the congestion window quickly to overcome the challenges of large latency networks.
