What is the Goal of finding IP Top Talker?

In my previous post I gave you 5 tips for analyzing packet captures.

In some cases it is necessary to identify which IP’s are talking the most in our network.

I really recommend these two ways to find the IP Top Talker. I also check that statistics even my goal is not to identify the Top Talker.

Both ways can be really helpful in many ways for you!
