Abstract
We 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
RTT, the slow-start mechanism currently employed does not
adequately fill the available bandwidth when the RTT is large.
Regardless, we show that CTCP still outperforms current TCP
variants (i.e., Cubic TCP and Hybla TCP) for high packet loss
rates (e.g., > 2.5%). We 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. Preliminary results are provided that show the
combination of network coding with an appropriate congestion
control algorithm can provide gains on the order of 20 times
that of existing TCP variants. Finally, we provide a discussion
of the future work needed to increase CTCP’s performance in
these networks.
