I am just reading this document to get some data to calculate RTT in
TCP. I think that you may find it helpful too.

Hello I m a novice NS user. If i want to see some throughput
comparison of TCP Reno, Tahoe, SACK --- which steps i need to follow.
If someone can help me providing some good URL for learning my
queries i will be grateful.

The Network Simulator ns-2: Frequently Asked Questions
(This FAQ is also on the web at
http://www.isi.edu/nsnam/ns/ns-faq.html.)
* _Where do I get ns?_
From the ns web site at http://www.isi.edu/nsnam/ns/ns.html and
the download page http://www.isi.edu/nsnam/ns/ns-tests.html.
* _What platforms does ns run on and what kind of hardware do I
need?_
Please see where to start on the building ns web page:
http://www.isi.edu/nsnam/ns/ns-build.html#start.
* _What should I do if I have trouble downloading/extracting ns?_
This question is answered in detail at
http://www.isi.edu/nsnam/ns/ns-problems.html#downloading.
* _What should I do if I encounter problems building ns?_
Check:
1. the README that comes in the distribution (very brief),
2. the installation problems, bug fixes and help web page
http://www.isi.edu/nsnam/ns/ns-problems.html,
3. the archives of the ns-users mailing list
http://www.isi.edu/nsnam/ns/ns-lists.html,
4. post a bug report (see below)
http://www.isi.edu/cgi-bin/nsnam/reportbug.cgi.
* _What do I do after I successfully build ns?_
+ Put the path to your ns executable into your PATH environment
+ Put the path to your otcl into your LD_LIBRARY_PATH
environment
+ Put the path to your tcl library into your TCL_LIBRARY
environment
* _Where can I find documentation for ns?_
All documentation is linked from the main ns web page
http://www.isi.edu/nsnam/ns/. Documentation includes a tutorial
(originally from Marc Greis) and a reference manual (ns notes and
documentation).
* _Words, words, words... that documentation is nice, but where are
some sample scripts I can start from?_
Many sample scripts can be found in the ns distribution in
~ns-2/tcl/ex and ~ns-2/tcl/test.
* _What protocols does ns support?_
A lot! Almost all variants of TCP, several forms of multicast,
wired networking, several ad hoc routing protocols and propagation
models (but not cellular phones), data diffusion, satellite, and
other stuff. See the documentation (described above) for details,
or download ns and look.
* _How do I know that ns correctly implements these protocols?_
Ns has validation tests that cover many protocols, see
http://www.isi.edu/nsnam/ns/ns-tests.html. However, ultimately
users are responsible for verifying that ns is accurate for their
purposes---since we cannot foresee all the ways ns may be used, we
cannot test all cases with all inputs.
* _Are there any contributed/additional protocols not in the main
distribution?_
Yes, please see the contributed code web page
http://www.isi.edu/nsnam/ns/ns-contributed.html. The mailing list
archives can also be helpful (see below).
* _How should I get started doing something (like implementing a new
protocol or trying an experiment)?_
We recommend that you look through the tutorial (see
documentation, above), then start with an example program that is
most similar to yours (in the tutorial, or in tcl/ex or tcl/test
in the distribution), and then start changing things.
* _What should I do to compile ns to reflect my changes if I've
modified some .cc or .h files?_
go to ns directory and run make or make depend; make
* _How do I subscribe to the ns-users mailing list? How do I search
old list archives? I can't take any more---how do I get off this
list?_
