Deadline: Sept 25, 2009
Solve the following problems from the textbook. These will not be graded (no need to turn in), but a set of solutions will be posted on the deadline date. There will be an in-class quiz on Sept 29 based on Chapter 1. Solving these problems will help you in the quiz.
- Problems P2, P5, P6, P13, P14, P24, P30, P32 from Chapter 1.
Solve the following problem. You will need to turn this in and it will be graded.
- Use traceroute to trace the route and round-trip latencies between a pair of nodes on the Internet. Use the same pair of nodes to run traceroute at least 10 different times during a one week period. Choose different times of the day if possible. Tell us your experience. Specifically, are the routes discovered in different runs the same? If not, why do you think that would be the case? Do the round trip times in different runs vary considerably? Why? Any other observation?
[Traceroute packets may be blocked for security reasons from campus. You may be able to use a machine on another ISP (home or place of work) that does not block such packets. Note that the traceroute command is called "tracert" on windows. You can also use any traceroute server on the Internet. You can use http://www.traceroute.org/ to find one. Or, google around to find one. To learn more details about how traceroute operates study RFC 1393.]
