<h1>Stop-and-Wait ARQ</h1>
<P>
This Java applet demonstrates the stop-and-wait automatic repeat request (ARQ)
mechanism of data link error control. Stop-and-wait ARQ is based on the
stop-and-wait flow control technique. The source station
transmits a single frame and then must await an acknowledgment (ACK). No other
data frames can be sent until the destination抯 reply arrives at the source
station. Two sorts of error could occur. First the frame that arrives at the
destination could be damaged. The second sort of error is a damaged
acknowledgment.
