Thanks for the pointer to your TCP Evaluation Suite at
"http://netlab.cs.ucla.edu/tcpsuite/".  I have added a pointer to
it on the TMRG web page at "http://www.icir.org/tmrg/".

Gang Wang, Yong Xia, and David Harrison have also worked on a TCP
evaluation suite, discussed in their internet-draft
draft-irtf-tmrg-ns2-tcp-tool-00.txt on "An NS2 TCP Evaluation Tool".
Their tool is available from "http://labs.nec.com.cn/tcpeval.htm".

The two TCP evaluation suites have somewhat different roles and
purposes;  yours is based on NS-2 Linux, and is specifically focused
on high bandwidth-delay environments.  Still, it seems to me that
it would be good for someone to look at the differences between the
two evaluation suites, and see where it would be useful for each
evaluation suite to borrow scenarios or approaches from the other.

Take care,
- Sally
