In the following four questions, we are sending a 30 Mbit MP3 file from a source host to a destination host. All links in the path between source and destination have a transmission rate of 10 Mbps. Assume that the propagation speed is 2 * 108meters/sec, and the distance between source and destination is 10,000 km. Initially suppose there is only one link between source and destination. Also suppose that the entire MP3 file is sent as one packet. What is the transmission delay?Referring to the above question, what is the end-to-end delay (transmission delay plus propagation delay)?Now suppose there are two links between source and destination, with one router connecting the two links. Each link is 5,000 km long. Again suppose the MP3 file is sent as one packet. Suppose there is no congestion, so that the packet is transmitted onto the second link as soon as the router receives the entire packet. What is the end-to-end delay?Now suppose that the MP3 file is broken into 3 packets, each of 10 Mbits. Use the same setup as in question 3 above. Ignore headers that may be added to these packets. Also ignore router processing delays. Assuming store and forward packet switching at the router, what is the end-to-end delay?
