FreeBSD 4.9 and TCP

[wilsonb]

Good Morning,

My name is Brian Wilson and I am currently studying computer science honours
at the University of the Witwatersrand in Johannesburg South Africa. As part
of our honours course we have to conduct some small scale research projects.

A number of us are in the position of having to use your FreeBSD product. We
are however having some difficulties in finding out whether or not it is
actually the correct product to be using and we have been unable to find the
necessary information in our numerous searches of the Interent.

We have to run tests on different versions of TCP, to measure performance
issues and the like.

What I would like to know from you is the following :

1) Which versions of TCP does the FreeBSD 4.9 distribution support and
implement -- we need to use TCP Reno, NewReno, Tahoe, SACK and T/TCP in our
experiments.

2) How exactly do we change the installation of FreeBSD to enable each of
these TCP types -- if you tell us where to look and what we need to change it
would be great

Essentially, what we need your help for is to find out exactly which versions
of TCP FreeBSD 4.9 is capable of using (seding and receiving) as well as how
to implement each of them separately.

If you could tell us what to do or at least where to look to find this
informaiton, it would be greatly appreciated.

Thank you
