[mpls-linux-general] Measure the delay jitter of video stream over MPLS network?

[Jing S. <js...@ca...>]

Hi:

Execuse me for my stupid question, but I really need help
on this question.

I've just setup a little test bed with MPLS & QoS enabled.
I want to measure the effect of QoS enabled MPLS channel
on video streams. I hope the test should be as simple as possible.

I've download a little tool named mpeg_video
which is a mpeg-1 decoder. I place the mpeg-1 files
on one end of the testbed(linux)  and mpeg-1 decoder on the other
end ( Solaris box). The decoder use NFS to fetch the content to play.
After reading the source code of the mpeg-1 decoder I find I
can just record the start and stop time of each frame, while I want to
measure the delay and delay jitter of each stream. And, I don't know if
there
is a free tool  can be used to generate a  graph of jitter-frame
relationship
from raw data.

Is there any person would like to do me a favor on this question?

Thanks a lot .

Regards
