i wouldn't want to get in an argument with somebody who was smart and savvy
enough to invent packet switching during the year i entered kindergarden,
but, somebody told me once that keeping information on every flow was *not*

I suggest reading the excellent page:
"High-Speed TCP Variants":
http://kb.pert.geant2.net/PERTKB/TcpHighSpeedVariants

Enough material there to keep NANOG readers busy all weekend long.
