CPSC 633a : Seminar on Computer Networks, Fall
- [12/05] I will be available tomorrow from 2 to 4pm.
Then I will be out of town from Dec. 7 to Dec. 16. I will be reachable through
email during this time. You can also talk to me, and my phone number

setup appointments to talk to me. Good luck in your finals!
- [11/26] The class home page on incentive-compatible
- [11/12] I did not address Stan's question clearly in
the class. I hope it will not cause more confusion. Before I re-explain the idea in next class, you can check the slides for update. The link to the paper is
here. Also, next class I will discuss a lower bound for secure group
rekeying. You are not required to read the paper on lower bound. If you are
interested in it, however, please refer to the
schedule page for a link to the paper.
- [10/26] I have changed the
paper for this coming Monday from [FGS01]
If you have already read [FGS01], you can submit its review instead.
However, it is strongly recommended that you read [LA00].
- [10/23] Please prepare for a brief talk on your
project. Keep the time to about 8 minutes and leave 4 minutes for questions.
If you need to use powerpoint, I will bring my laptop to the class. In the
talk, please try to address the following questions: What is the problem? Why
is the problem interesting? Why is the problem difficult? What is the previous
work? What is the idea to solve the problem? What is the methodology to
justify your solution? What is the expected deliverable?
- [10/21] I have added a few more potential topics to
list. Please be prepared to say a few words about your project. If you are
still looking for project partners, it is a good opportunity to say what you
are interested in the class.
- [10/20] When reading the paper for Monday's class, try to
think the relationship between bandwidth adaptation and playout buffer. Also,
you can check the slides for Monday's class, and think about some of the
questions on the slides.
- [10/11] We will not have class next Monday. Also, I have
linked several tutorials
on the reading list (I always find reading tutorials is easier than reading
- [10/09] Try to think of the following problems before
Wednesday's class: How do we regulate people's behavior in a society?
How do we allocate resource in an economy? Can we borrow ideas from these
fields to provide incentives for users to regulate their sending
- [10/08] The main TCP security issues we will discuss this
Wednesday are related with congestion control. For those who are interested in
general security, here is Joncheray's
paper about a simple active attack against TCP which takes over a
connection after the user authentication has been done (e.g. Kerberos). As an
is the source code. You are not encouraged to try it out, but are
encouraged to read the code. If you are really curious, you can read a sample
log. Also, the paper mentions about nmap, which uses "fingerprint" to
detect the os of a machine, here
is the link. Since we did not cover the state transition diagram of TCP (which
will be covered next semester), you may have to read Steven's textbook in the
- [10/02] Here are a couple questions for you to
think about for tomorrow's class: 1) The authors considered three classes of
schemes: link layer, end to end, and split connection. What is the best scheme
that was considered for each class in this paper? What is the best scheme you
can think of for each class? 2) From the paper, the authors showed that their
best scheme in the link layer class is better than their best scheme in the
split connection class. Why?
- [10/01] If you are interested in wireless network, the
congestion control, is a comprehensive survey on wireless congestion
- [09/30] Please take a look at the list of project topics.
You are welcome to come up with your own topics. Talk to me before you make
- [09/26] In Monday's class, we will try to debate on
TCP/Vegas. Try to think how and why TCP/Vegas improves over TCP/Reno. What are
the advantages? What are the disadvantages? Will it work if we introduce
TCP/Vegas into the current Internet?
- [09/13] For those who are interested in wireless, you can
find a nice tutorial: routing,
MAC, and mobility in Ad Hoc network. For the class next Monday, you can
read the part on wireless MAC, which starts from page 254 and ends at page
- [09/12] If you are interested in the possibility of
infinite bandwidth and its effects, you can read the interesting book [Gil00].
- [09/12] For the problem of CIDR on IP table lookup,
please see the papers in the high performance router section, e.g., [SSV99].
- [09/10] Starting from this Wednesday (9/12), we will
move our class from AKW 200 to AKW 500.
- [09/10] Instead of I listing the names of the students,
everyone attended class today can enroll.
- [09/10] Please make sure that your reviews are world
- [09/09] The instruction on how to submit your reviews is
Note that I have also revised the review
- [09/09] For those who are wondering between CPSC 633a and
CPSC 433b, please take a look at the topics of CPSC
433b. Here are my suggestions
on which class you may want to take: CPSC 633a, or CPSC 433b. You can take
both. If still in doubt, please talk to me.
- [09/05] Please take the class
