- Yes, but, as far as I know, it's not required that the sending TCP stuff
- everything into one packet, and there's a "TCP Big Window" option
- mentioned in RFC1106, to increase the maximum window size beyond 64K.
-
- There's also an RFC, RFC1110, entitled "A Problem with the TCP Big
- Window Option"; both date back to mid-1989, and not being a full-time
- networking weenie, I don't know what the state of Big Windows in TCP is
- (except that I seem to remember Vernon Schryver talking about cranking
- the window size up when using FDDI, in order to light the fibre up, so I
- suspect there's at least a semi-stable standard for Big Windows).
