TCP-Peach and FACK/SACK options: putting the pieces together

TCP-Peach has been proposed for IP network scenarios characterized by long round trip times and high bit error rates, such as satellite networks. In the TCP-Peach congestion control scheme, Slow Start and Fast Recovery are replaced with new algorithms called Sudden Start and Rapid Recovery. In this paper protocol refinements for TCP-Peach are proposed to allow it to be utilized in cooperation with FACK/SACK options. The modified protocol has been implemented in the Linux 2.2.17 kernel and its performance has been evaluated in an emulated satellite network environment. Performance results show that the modified TCP-Peach protocol outperforms other TCP implementations.
