hello,
I have the same problem. It's a good question.

Hi,
I am hoping someone can offer some advice with QoS analysis I hope to
be able to achieve.
I am sure there are many who might need this capability.
What I would like to do is the following:
1) Setup Ethereal / TCPDUMP to capture VoIP packets for a period of time.
2) Run the trace file through a tool (ideally Ethereal) which will
analyse the RTP packets for Jitter, lost packets etc, and give an
summary of results.
Currently Ethereal is able to give Jitter, Lost Packets for each
individual RTP stream, which is excellent
when you only need to analyse a few RTP steams, but it is not capable
of giving average results for a large number of RTP streams.
The results I would think would be useful would be :
Average Jitter Levels for all calls.
RTP Stream with Highest Packet loss.
Steam with Highest Jitter Levels.
Standard Deviation of Jitter Levels for all RTP steams.
This information could be found using Ethereal IF it was possible to
export the information in Ethereal's RTP Streams Page to a CVS file.
I.e. And then use Excel (or some other application) to gather the
average results , STD etc.
However currently this is not possible.
Does anyone have any other ideas how this might be possible?
Rgs,
Gerard.
