Is there some network package format analysis for online game?

[yech]

Dear all,

I'm trying to find an anti-cheat solution for aoc 1.0a. I guess the cheater should modify some local memory data and send bogus network package to sync the local modification to other players to prevent the out of sync detection. So I want to detect the cheat by finding out the bogus network package. Is there any of the network package analysis or related work done?

Thanks a lot!
