Lisa Bock covers analyzing RTP traffic streams in Wireshark, where you can compare the jitter between streams and graph the streams. She shows how to export the chart in one of many formats to save and analyze it at a later date.
- [Instructor] When working with Wireshark…and a voice over IP packet capture, there's…a number of different statistics we can do…to analyze the traffic flow.…If you'd like to follow along, I'm on CloudShark…and I got this packet capture where we can go…to export, download file, and then open it in Wireshark.…So we've used this before and it is just…a nice little capture.…And as you can see, we do have real-time transport protocol.…We see it in there and let's see if we can get…it to come up under the menu choice telephony.…
Go to telephony and RTP.…Wow, okay, we see the streams and stream analysis.…Well, what we have to do is help Wireshark…by letting Wireshark know that we do have this traffic.…So type in the display filter RTP.…Now, once you get in there, select one…of the streams and then go to telephony and RTP.…And we'll start with stream analysis.…Now, if we go to stream analysis, I have selected…one of the streams.…
You can see what it did was it, let's pull…this over here.…You can see this is a single stream.…
