Hi,<br><br>Which network impairment tool would you use to teach QoS and VoIP in a lab, with limited budget ?<br>Ideally, I would set different network conditions with it (jitter, packet loss).<br><br>I've seen those tools :
<br><br>- NIST Net (<a href="http://www-x.antd.nist.gov/nistnet/" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">http://www-x.antd.nist.gov/nistnet/</a>)<br>- UDP Packet Reflector/Forwarder (<a href="http://www.cs.ucl.ac.uk/staff/s.bhatti/teaching/z02/reflector.html" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">

http://www.cs.ucl.ac.uk/staff/s.bhatti/teaching/z02/reflector.html</a>)<br>- IP DummyNet (<a href="http://info.iet.unipi.it/%7Eluigi/ip_dummynet/" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">http://info.iet.unipi.it/~luigi/ip_dummynet/
</a>)<br>- Telechemy IP Impairment simulator (
<a href="http://www.voiptroubleshooter.com/diagnosis/index.html" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">http://www.voiptroubleshooter.com/diagnosis/index.html</a>)<br><br>I would be very curious to know your own rating of those.
<br>Do you know any tool using Linux iptables to offer, like IP Dummynet seems to do with FreBSD, tunable network conditions ?
<br><br>Cheers
