FINALLY TIME

FINALLY WE DID IT IN THIS WAY. BUT IT'S NOT GOOD AT ALL. WE USE THREAD
IN TCP LAYER , HOWEVER, THE OVERHEAD AT IP SEEMS TOO MUCH. SO WE ADD
FOR(10^9) TO ADD SOME ACTIONS ON AP KERNEL TO BALANCE THE OVERHEAD.
MYTCO0605.TCPDUMP IS A BAG WITH JUST TCP BAG. WE COULD USE TCPREPLAY TO
PLAY ALL THESE THINGS.
