Hi all,

We are doing some experiments using the OpenBSD implementation of TCP SACK
and FACK. Could anyone validate for us whether these are the docs that
these implementations conform to (or are closest to)?

OpenBSD TCP-SACK: A Conservative SACK-based Loss Recovery Algorithm for
TCP (draft-allman-tcp-sack-13.txt)

OpenBSD TCP-FACK: SIGCOMM'96 Paper "Forward Acknowledgment: Refining TCP
Congestion Control"

If not, then which are the implementations available right now that do?

Further, do the ns-2 implementations of TCP-SACK/FACK conform to the docs
above?

thanks and regards,
jana/armando
