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).
