Lisa Bock demonstrates the ability of Wireshark to analyze UDP multicast streams. Lisa creates an IO graph in Wireshark to view the UDP Multicast Stream to check for excessive burstiness and output drops.
- [Instructor] When you take a look at normal traffic,…we know that TCP has a natural burstiness to it.…And that would include your HTTP, email, Facebook, YouTube,…we know that that traffic is going to be bursty and it happens.…It's because on the other side I can put it back…in the order it's supposed to be in.…Voice and video generally we're going to see a constant stream.…Now can we take bursty traffic?…Well here's the thing,…you really should test for UDP burst…and periodically if you're wondering why…are you having so many problems receiving the traffic,…let's take a look.…
If you have this network device…and here's your network device,…just any device on the network.…And if the traffic is bursty…before it enters the network device,…that packet represents the buffer space.…In most cases, it's just unable to handle…that amount of traffic,…and it will then cause an output drop…and you will not get it.…So how are we going to check that?…Well, I want to take you to this website…you can go to, the Wiki, wireshark.org…
