Playing with ping: Use the ping command to measure and report the average round trip time between attu.cs.washington.edu and the following machines: (a) www.cs.washington.edu (b) www.cs.berkeley.edu (c) www.google.com (d) www.cs.nyu.edu (e) www.cs.monash.edu.au For each, estimate the physical distance between attu 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?
