[ee122] question about winsize and ack in tcp

[Davide Cerri]

Hello,
1 - if i advertise a window size of zero will the other side of the
connection stop to send packages?
2 - if i have a window size that can fit 5 packages and i receive
packet 1 2 4 5, when i send the second duplicate ack, do i advertise a
windowsize of 0 or of 1 ?
3 - is it correct to always try to send the min(CWND, windowsize)?

Thanks.
