The logistics of project submission has been worked out with the help of

the details of submitting your work at the project page under "project
Rosa will lead a review session for exam 1 on Wed, 10/9, during the regular
class time (11-12:30pm). She will go over the exam from last year,
and answer any other questions that you have. Therefore, the exam
solutions will not be posted here online beforehand, as originally promised.
We will move on to the next topic (Internet Protocol) for next Monday
(10/7). Please read ahead to chapter 17. If you haven't done
so already, you should also read Chapter 25 (Internet Routing) which we
covered in class today.
I am posting last
year's exam 1 for your reference. I will post the solutions in
a few days.
Policy regarding project deliverables: as stated in the project description,
you need to have your project report and presentation slides submitted
24 hours before your scheduled presentation time, so that your classmates
can review the material beforehand. However, you have the option
of submitting a revised version of your report and slides (if you so desire)
by November 8.
I've posted new versions of today's lecture slides. Please let
me know if you are still experiencing printing problems.
I did a demo of MapNet
in today's lecture. You can find pointers to this and other nifty
tools (e.g., applets showing the operation of CRC) at the course resources
page ( http://www.sims.berkeley.edu/academics/courses/is250/f02/Resources.html
The tentative project presentation schedule
has been posted. If you have any scheduling conflicts (e.g., if you
need to be out of town for a conference, etc., please let me know ASAP).
A clarification on homeworks: you are welcome to form study groups and
discuss homework assignments, but you have to submit your homework assignments
For those of you who are not familiar with hexadecimal numbers and how
to convert them to decimal or binary, or vice versa, here is a handy conversion
table ( http://www.cisco.com/univercd/cc/td/doc/product/tel_pswt/vco_prod/ext_prg/exprb.htm
) that you can refer to. By the way, you can find this and many other
useful resources at the course resource page (http://www.sims.berkeley.edu/academics/courses/is250/f02/Resources.html).
Finally, I've regenerated the pdf files for the lecture notes (for transmission
media and channel capacity) and hopefully address the printing problems
that some of you have been experiencing. Please let me know if you
are still encountering printing problems.
The following message is from Susan Reneau, Student Affairs Officer of
the MOT (Management of Technology) program. Please contact her if you have
Haas office (new): F477, 643-1398
Engineering office: 230 Bechtel, 642-8790
1) Students taking a class towards the MOT certificate, must take it
for a grade, not pass/fail.
2) They must receive a B or above.
3) All students going for the MOT certificate should refer to the MOT
website (mot.berkeley.edu). It has detailed information about the certificate
and the classes.
Also, since this course is cross-listed in three schools (SIMS, Haas,
Engineering), students should make sure that they are not registered using
another college's CCN, even though Telebears will allow it. This can cause
double registration and much hassle.
Homework 1 is assigned today, and due in one week. Check the assignments
page for submission details and policy.
Prof. Chuang's office hours will be Wednesdays 2-3pm. You can
also send him email to set up individual appointments at other times. Please
note that his office is moved from South Hall 313 to 312 (one door down).
Please subscribe to the is250 mailing list if you haven't done so already.
If you are a SIMS student, you can do so via my.sims. If you are
a non-SIMS student, send email to email@example.com and include
"subscribe is250" as the first line of your message. (You can leave the
subject line blank.)
