Wireshark · Ethereal-users: Re: [Ethereal-users] RTP Traffic Generator

[Vijay Shyamasundar Shyamasundar <vijayshyamasundar@xxxxxxxxx>]

Hi Olivier,

Thanks for the information. This helps. I am actually trying to
saturate an 802.11b network with RTP traffic simulating voice calls to
find out the max number of simultaneous calls possible over our network
for a given MOS. I have a customized linux box that analyzes the
packets and determines the MOS. Unfortunately, that customized hardware
doesnt have a wireless interface, i have set up a linux bridge that
grabs traffic from wireless lan and forwards it to our analyzer through
an eth interface. I wanted to generate some RTP traffic and evaluate
the accuracy of  our analyzer throug hthis approach. Hence, i
needed to generate some RTP traffic. 

Regards,
Vijay

Hello,

 

you could use SIPp (http://sipp.sourceforge.net/ ) to send SIP+RTP traffic.

 

AFAIK, there is no tool to compute MOS (well, more exactly that will compute a PESQ/PAMS/PSQM or r-factor and map it to a MOS score) released in Open Source.

The algorithms are public but have to be licensed to be used. Maybe others have a different experience...

Hi All,

 

Could anybody tell me if there is any software available to generate RTP traffic to simulate a VoIP call other than packETH and RTPGen. 

 

I also wanted to know if there was any tool that sniffs packets over the air and analyzes the MOS without requiring any special hardware.

 

Regards,

Vijay
