Question
Choose a destination host and use traceroute command
to run three experiments corresponding to the different days and time of the day.
a) For each experiment, run traceroute for 10 times and note down the end-to-end RTT. Calculate
the average and standard deviation of this RTT for each experiment.
b) Find the total number of hops reported for each experiment. Do you observe any change on
the network paths between the three experiments?
c) Try to identify the number of different ISP networks contained on the network path. Assume
that the hops with similar names and IP addresses belong to the same ISP. Which two adjacent
hops have the largest delay?

b) Find the total number of hops reported for each experiment. Do you observe any change on
the network paths between the three experiments?
yahoo.co Uk
some times differnt paths but every time it takes 16 hops

it took same path all time and every time it took hops

it took same path nd
c) Try to identify the number of different ISP networks contained on the network path. Assume
that the hops with similar names and IP addresses belong to the same ISP. Which two adjacent
hops have the largest delay?
