When the packet reaches its destination, a design flaw attempts to create a window size for the packet if the port is open, flagging the window field of the packet with 1's before it returns to the sender.
Kada paket stigne na odredište, mana u dizajnu pokušava da napravi prozor veličine paketa ako je port otvoren, obeležavajuci polje prozora paketa sa 1 pre nego sto se vraća pošiljaocu.
