Connection Info Tab Descriptions?

[NouberNou]

Does anyone have any idea what some of the other tabs in Connection Info represent when you view it on a person?

The first two and the last are pretty obvious, but what does Keep Alive and Control measure?

Any info in regards to this would be very helpful in diagnosing some issues I am having with a plugin.

Keep Alive should be small packages that are send between server and client so both know the other party is still there, so the connection does not get terminated.

Not entirely sure about Control but I'd guess thats you/other clients switching channels, changing your status in some way (Mute mic, set yourself away etc.) so the server knows about your new status and can send it to other clients.
