Homework 2
Textbook problems: 2.50, 2.58, 3.3, 3.4, 3.13, 3.17, 4.1, 4.4, 4.8, 4.15, 4.17, 4.18 Playing with ping: Use the ping command to measure and report the average round trip time between cs01.erin.utoronto.ca and the following machines: (a) www.toronto.edu (b) www.ubc.ca (c) www.cs.nyu.edu (d) www.cs.monash.edu.au For each, estimate the physical distance between cs01.erin.utoronto.ca and the destination. Calculate the speed-of-light round-trip delay given this distance. At what fraction of the speed of light did your ping packets travel, for each? Bonus traceroute problem: Use "traceroute" to determine the path taken between cs01.erin.utorontoc.ca and www.japan.co.jp. From its output, using your powers of sleuthing, google, and best guesses, describe the geographical path the packets take -- cities and countries. |
