Perform a Traceroute between source and destination on the same continentat three
Chapter 1, Problem P18(choose chapter or problem)
Perform a Traceroute between source and destination on the same continent at three different hours of the day.
a. Find the average and standard deviation of the round-trip delays at each of the three hours.
b. Find the number of routers in the path at each of the three hours. Did thepaths change during any of the hours?
c. Try to identify the number of ISP networks that the Traceroute packets pass through from source to destination. Routers with similar names and/or similar IP addresses should be considered as part of the same ISP. In your experiments, do the largest delays occur at the peering interfaces between adjacent ISPs?
d. Repeat the above for a source and destination on different continents. Compare the intra-continent and inter-continent results.

ANSWER:Step 1 of 5
The trace route can be determined by using commands. It is different on operating systems. On Linux we can use the command traceroute www.targethost.com and in the Windows command prompt we can use tracert www.targethost.com
In both cases, we will get three delay measurements. For those three measurements we can determine the mean and standard deviation. Repeat the experiment at different times of the day and comment on any changes.
