A frame of size 1500 bytes that is being sent on a link with 10 routers each having a queuing time of 2 s and a processing time of 1 s. The length of the whole link is 200 Km. The speed of light inside the link is 2 x 108 m/s. The link has a bandwidth of 5 Mbps.

1- Draw the communication system showing the sender, receiver, and the routers.

2- Calculate the total delay end-to-end.

3- Which component of the total delay is dominant?

4- Which one is negligible?
