The LBNL Network Simulator, "ns", is now publicly available in
ftp://ftp.ee.lbl.gov/ns.tar.gz.  ns has undergone a gradual design
evolution over the past several years; it began as a variant
of S. Keshav's REAL simulator in May 1990.

Ns simulations are described in an extension of the tcl programming
language, which makes simulation description highly flexible.
The internal implementation is object oriented (C++) and it's
easy to add support for new traffic sources, routing disciplines etc.

See http://www-nrg.ee.lbl.gov/ns/ for more details.

ns (previously known as "tcpsim") was used in Floyd's work
on RED gateways, resource management, class-based queuing,
explicit congestion notification, and traffic phase effects.
(Many of the papers discussing these issues are available
via the Network Research Group URL listed below).

Please direct ns-related correspondence to ns@ee.lbl.gov (which
includes only the developers and is not distributed beyond our site).
