# The Best Questions About Networks

Perform a Traceroute between source and destination on the same continent
at three different hours of the day.

Firstly over UNIX you’ll be able to use the command

traceroute www.targethost.com

And after that within the Windows CMD you’ll be able to use

tracert www.targethost.com

In either case, you may get 3 delay measurements. For those 3 measurements you’ll be able to calculate the mean and variance. Repeat the experiment at completely different times of the day and discuss any changes.

Here is a model explanation:

Traceroutes between point of entry between www.poly.edu and SCC
a. Find the average and standard deviation of the round-trip delays at each of
the three hours.

The typical (mean) of the round-trip delays would usually come as 1.18ms, second would be 71.38 & last would be 1.55ms at every of the 3 hours delay respectively. The quality deviations square measure zero.075 ms, 0.21 ms, 0.05 ms, and severally.

b. Find the number of routers in the path at each of the three hours. Did the
paths change during any of the hours?

During this example, the methods didn’t modification throughout any of the hours. Within the path at every of the 3 hours the traceroutes have twelve routers.

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?

Traceroute packets undergone four ISP networks from supply to destination. Yes, during this experiment the biggest delays occurred at peering interfaces between adjacent ISPs.

Traceroutes from www.stella-net.net from one country to www.poly.edu in another country

d. Repeat the above for a source and destination on different continents.
Compare the intra-continent and inter-continent results.

The typical round-trip delays at every of the 3rd hour are  86.35 ms and 87.09 ms, 86.48 ms, respectively. The quality deviations are zero.53 ms, 0.18 ms, 0.23 ms, and severally. During this example, there are eleven routers within the path at every of the 3 hours. No, the methods didn’t modification throughout any of the hours. During this experiment the biggest delays occurred at peering interfaces between adjacent ISPs. As the Traceroute packets distributed over 3 ISP networks from supply to destination.
