[ns] Need OBS simulator

[Phivos Petrou]

Hi,  
  
I am trying to create a simulation of a network that uses TCP over OBS
using ns-2.  
The problem is that I can't download the OBS simulators that I found
which are: 

1. OIRC OBS-ns Simulator from http://wine.icu.ac.kr/~obsns/ 
2. OBS-ns simulator from University of Maryland DAWN research lab
(http://dawn.cs.umbc.edu/owns/) 

I can't download the first one because when I fill the form with my
email and other information, I receive an email with a link to a page
that says that this page is expired. 
The second one it's because when I try to follow the link
http://dawn.cs.umbc.edu/owns/ says that I don't have access to that
directory.  

Thanks for your time
