CoD ghosts on xbox 360(and xbox one) network protocol

[superbadkid]

Hello,

Just wondering if people knew if the protocol was encrypted or compressed?

I'm essentially looking for header information in each in game packet. But I can't see anything in common other than the first 4 bytes. Bytes 1,2,3 are always the same. And byte 0 is always 0x_f. So the blank changes occasionally. This is true for the client and the server.

There appears to be a game start-up, that always has 0x00000000 as the first word.

Any info on the protocol would be much appreciated.
