Unidirectional Network Link Simulation

This illustrates two nodes communicating over a unidirectional network link, with A sending packets to B. Try varying the parameters to see how they affects the packet delivery. You can click "emit" multiple times to send more than one packet. If you send too quickly, packets will be queued at A before being transmitted on the link (current queue size is shown as "Q:").

Bandwidth R: 0 kb/sec, the rate at which A transmits bits onto the wire.
Wire Length M: 0 km, the length of the wire connecting A and B.
Packet Size L: 0 bytes, the length of the packet.

Propagation Speed $c$ = $2.0 * 10^8$ m/s (i.e. speed of light in a fiber)
Transmission Delay $D_xmit = L / R = {Dxmit:ms}$
Propagation Delay $D_prop = M / S = {Dprop:ms}$
Total Delay for each packet $D_packet = D_xmit + D_prop = {Dtotal:ms}$
