Hello,
finally I've got the time to finish the measurement of SRT of H.225 RAS
services. New source files and patches for existing source files, docu
and makefiles are attached.
Current limitations:
At the moment Request-Response matching works only for RAS messages with
message tag < 21 .
Request-Response matching probably doesn't work with GRQ multicasts.
I will be glad, if someone can send me a capture file with a GRQ
multicast message and corresponding response.
Implementation Notes:
I put the stuff for hash tables and memory chunks in a seperate file.
The protocol tree of H.225 RAS Response messages contain now the Service
Response Time and the frame number of the matching request if available.
The matching request contains then also the frame number of the response.
This makes it easy to find the request to a selected response in a big
capture file by using the "Go to corresponding frame" feature. This is
especially very useful, when you are looking for the corresponding
request to a reject message.
The protocol tree of ACF/ARJ an DCF/DRJ messages contain now the Call-Id
of corresponding requests as a hidden protocol tree item. A hidden item
isn't displayed, but the display filter gets it.
This makes it much easier, to set a filter for all h225 messages of a
specific call including the RAS responses. Just use "h225.guid == ..."
and you will also get the call related RAS Responses.
Best Regards,
Lars
