Query regarding the ns source

[Mr Kashinath Basu <kbasu@dsrg.brookes.ac.uk>]

Dear Sir,

I am a PhD student at the Distributed Systems Research Group at Oxford
Brookes University, UK. I plan to do some multicast simulation using ns.
I tried to download ns, but the URLs at the ns download homepage
(Berkeley site) dowloads html page about ns change log. I will be very
grateful if you kindly provide me the address from which I can get the
ns software so that I can build it.

With regards,
Kashinath Basu
