4. What does propagation delay depend upon?

How is propagation delay affected if the length of the packet is increased?

How is propagation delay affected if the length of the packet is increased? This delay is just a function of link length and its physical characteristics, so it is NOT affected.

What is maximum propagation delay?

The propagation delay t_pd is the maximum time from when any input changes until the output or outputs reach their final value. The contamination delay t_cd is the minimum time from when any input changes until any output starts to change its value.

What happens if propagation delay is greater than transmission delay?

Propagation delay : It's the amount of time needed for a packet to reach the destination. If propagation delay is very high than transmission delay the chance of losing the packet is high.

What does propagation delay depend upon?

A propagation delay depends on the distance and propagation speed.
