Subject: TCP / IP

I am just a student learning about TCP/IP and dont
know where to post this idea, figured posting it here
would get me some flames and links.

Why not make the window the size of the file to be
transmitted and the ack back have the segments missing
thereby reducing overall overhead and lag time.

ie 

host1 1mb file --- sent -- > host2

host1 <-- ack missing 3 6 8 segments -- host2

host1 -- segments 3 6 8 sent ---> host2

host1 <-- FIN --- host2

The window could be dynamic according to content size.

Buffers would have to be huge but with RAM so cheap
these days why not ?

or am I smoking newbie crack ?

Dan
