Exercise 1:

We are sending a 7.4 KB (care this is kilo bytes!) file from a source host to a destination host. All links in the path between source and destination have a transmission rate of 8 Kbps. Assume that the propagation speed is 2 * 10^8 meters/sec, and the distance between source and destination is 40,000 km. Reply to the following questions.

Question:Now suppose there are eight links between source and destination (7 routers in the path between source and destination). Each link is 5000 km long. Again suppose the file is sent as one packet. Suppose there is no congestion, so that the packet is transmitted onto the next link as soon as the router receives the entire packet. What is the end-to-end delay(transmission delay plus propagation delay)? Remember to add headers.
