MultiTCP[1] is (yet another) Linux TCP patch intended for researchers/developers, which can report TCP events in the kernel logs in order to watch TCP internal variables.
Furthermore, it includes TCP Pacing and Hoe's initial ssthresh estimation[2]. Their use in satellite links is strongly recommended by the TCP-Hybla authors in order to mitigate congestion episodes and limit the initial cwnd overshoot phenomenon respectively. A new version for linux-2.6.19 has been released at http://www.sf.net/projects/multitcp/ Hybla's authors future goal would be to produce official patches for both Pacing and initial ssthresh estimation, by freeing the latter one implementation from the TCP kernel logs engine and getting the current tcp_sock structure slimmer. Meanwhile, we will appreciate if the comparative tests made on Linux congestion control will include the two algorithms described above when using TCP-Hybla. [1] C. Caini, R. Firrincieli and D.
