Transmission vs Propagation Delay

This animation illustrates the difference between transmission and propagation delay.

You can set the length of the link, the packet size, the transmission speed, the propagation speed of the link; The animation shows the packet being sent from sender to receiver
Note that for many combinations, the head of the packet reaches the receiver before transmission is finished at the sender.


sets the distance between sender and receiver in km

sets the data rate

sets the propagation speed

sets the size of the data

starts or restarts the simulation
