Data Communications and Networking

1. Suppose an application sends messages of 100 bytes 90% of the time and messages of 900 bytes 10% of the time. The transport, network and datalink layer add header/tails of 20, 20 and 18 bytes (TCP, IP, Ethernet) respectively. What is the maximum percentage of actual application data that this application could achieve across any network?


2. Suppose a 2 MB file is transmitted over a 4km fiber link, propagation speed of 2 * 108 m/sec., at 100 Mbps. How long does it take from the first bit sent until the last bit to arrive at its destination?
