an Emulab if you do not have a dedicated intranet lab.
Comments on the use of Hands-On Networking
I am now looking back on using Hands-On Networking
for the fourth time during the Spring 2007 semester.
gives a pretty accurate idea of what we did. I had six
students of various levels of experience. One was clearly
outstanding and has a Research Fellowship at the University of
Kentucky next year. As a whole the class was enthusiastic, but
a few of the students had trouble getting their assignments
done (though by the end of the semester all were very nearly
caught up). The big story this year was the introduction to
the course of the Calvin Emulab, built with the support of an
NSF grant. It was ready to go about halfway through the
semester and was used in the course.
This year's assignments had a clear, logical flow.
- Extend the sample programs from Chapter 6 into a TCP file
- Modify that program from TCP to UDP.
- Take the UDP file transfer programs, and modify them so
they work through the Gateway (Chapter 8) which drops,
corrupts, and reorders packets. One student did this on the
Emulab over a link set up to lose packets.
- By this time the Emulab was pretty much ready to go, so
the next assignment was to set up a link, run the TCP software
over it watching traffic with tcpdump, and then start the UDP
software. The TCP traffic not only slowed to a crawl (with the
right parameters), it stopped!
- For the final project the students formed two teams and
worked on multicast. They took a very different approach, but
both did well.
