Solaris 2.6 doesn't do SACK, but it does contain the New Reno
algorithm. There is an experimental SACK implementation available from
Sun for 2.6. See messages below.

We have made available an experimental TCP module with SACK for Solaris 2.6
(SunOS 5.6). URL is
ftp://playground.sun.com/pub/sack/tcp.sack.tar.Z
There is a README file in the archive about how to install it. Note that it
is NOT a production release, and is only for experimentation.
If you find any bugs or have any suggestions, feel free to send them to me.

2.6 has the New Reno algorithm. Refer to Hoe's SIGCOMM paper, URL is
http://www.acm.org/sigcomm/sigcomm96/papers/hoe.html, and Fall and Floyd's
paper, URL is http://ftp.ee.lbl.gov/floyd/sacks.html.

The default maximum buffer size is 1M. This is controlled by the ndd
parameter tcp_max_buf. Parameter tcp_cwnd_max controls the maxiumum
congestion window size.
