Re: TCP / IP

[Honza Vlach <janus () volny cz>]

Hi,
actually, the window says how much the other host can accept due to e.g.
link congestion, disk activity etc. There is no point in sending more
data than the destination can handle, because it would ack the part of it
and everything after the error must be retransmitted.

So in your example, if host sees that segment 3 is missing, it's pointles
if it has 4,5 and 7. Retransmissions would go from segment 3. 

HTH,
Honza
