Question

P18. Perform a Traceroute between source and destination on the same continent at three different hours of the day.

(using following picture's infomation to answer questions)

  1. Find the average and standard deviation of the round-trip delays at each of the three hours.
  2. Find the number of routers in the path at each of the three hours. Did the paths change during any of the hours?
  3. 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?
  4. Repeat the above for a source and destination on different continents. Compare the intra-continent and inter-continent results.
