EE450, Fall 2006, Zahid EE450: Computer Networks Homework #1, Fall 2006 Due Tuesday , September 5 Reading Assignment: Read Chapter 1, entire Text Problems: Chapter 1, Page 63: Problems 4, 6 and 7 Supplementary Problems: 1. A collection of 5 nodes is to be connected. Between each pair of nodes, the designers may put a high-speed line, a medium-speed line, a low-speed line or no line. If it takes 100 msec of computer time to generate and inspect each topology, how long will it take to inspect all of them? Explain (i.e. I am not looking for answers only) 2. Assume you have "n" hosts in a network. How many links are required for a a) Fully connected mesh topology b) Ring topology c) Bus topology d) Hub topology 3. How long does it take to transmit x -KB over a y -Mbps link? Give your answer as a ratio of x and y . 4. Calculate the total time required to transfer a 1000-KB file in the following cases, assuming an RTT of 100 ms, a packet size of 1 KB data, and an initial 2xRTT of "handshaking" before data is sent. (Total time = handshaking + transmit time of
