The sending window limits the sender to a maximum of 5 outstanding,
unacked data packets. To create new data packets, click "Send New". This
action will begin moving data packets between sender and receiver.
To simulate loss, select a moving data packet or ack, and then press
"Kill Packet/Ack". Use "Pause" and "Resume" to make selecting easier.
Speed up or slow down the simulation
by clicking "Faster" or "Slower". BE PATIENT for retransmissions (i.e., timeouts).
