This is a special-topics course on Internet Telephony. The prerequisite for
this class are Operating
Systems and Networking.
The course is divided into six two-week sections; see the syllabus for details.
The class meets Tuesdays and Thursdays from 4:00 p.m. to 5:50 p.m. in Howard
Hall 524 C-1.
This course has three objectives. By the end of the semester, you should have
an understanding of
the basics of Internet Telephony,
the underlying implementation technologies, and
possible for future directions for Internet telephony applications.

p.m. on Tuesdays and Thursdays in HH C1; see
schedule for details.
The usual grade ranges are in effect:
All grades are kept with one digit of precision to the right of the decimal
point and 0.05 rounded up. No grades are adjusted to a curve; that means, for
example, that 89.9 is always a B+, never an A-.
There are six quizzes, one each section on Tuesdays (except the last quiz,
which is on the final Thursday); see the syllabus for the schedule. Quizzes are
given in class, and are closed book with no notes; calculators and computers
will not be necessary. The quizzes are cumulative, covering everything taught
up to and including the class before the quiz. Quizzes should take no more
than an hour to complete, and are given in the first hour of class. Quiz
answers will be made available off the syllabus. There are no mid-terms or finals.
Each student should pick one or two papers (depending on class size and time)
of interest having to do with Internet Telephony and lead a presentation and
class discussion about each paper. Here are some guildelines
for presenting a paper.
It would be nice if there were some programming assignments, but at the moment
it's unclear what they could be. If there are some programming assignments,
the grades for the assignments will, perhaps, substitute for low quiz or

There is no textbook for the class (or rather, there are many textbooks for
this class, each one useful only in parts). Reading for this course will come
from lecture notes and papers in the literature. See the syllabus for details.

Mail relevant to the class are stored in a

suitably stripped of identification and along with my answer, in the archive.

should get in the habit of checking the syllabus regularly.
People who need assistance or accommodations above and beyond what is usually

I have no class attendance policy; you may attend class or not as you see fit.
However, I hold you responsible for knowing everything that goes on in class;
"I wasn't in class for that." is not an acceptable excuse for a wrong
answer, or for giving no answer at all.
My attendance policy applies only to lecture attendance; it does not apply to
other kinds of attendance which may be required for the course. Repeated
failures to meet the attendance expectations set for tests, meetings, projects,
labs or other forms of course work will have a bad influence on your grade.
I deal with suspected cheating by failing first and asking questions later.
Although cheating has many forms, I generally consider cheating to be any
attempt to claim someone else's work as your own; also, I consider both the
provider and the user of the work guilty of cheating. See the chapters on
Academic Information and the Student Code of Conduct in the Student Handbook
for more details.
I recognize and encourage a student's sacred right to complain about their
grade. There are, however, a few rules under which such complaining should
take place, and those students who don't follow the rules will be less
successful in their complaints than those students who do follow the rules.
First, the only complaint that matters is that something got marked wrong when
it was actually right. When you come to complain, be prepared to present, in
explicit detail, what it is you did and why you think it's right.
Second, complaints about a particular test or assignment are only valid until
the next test or assignment is due; after that point the book is permanently
closed on all previous test or assignment grades.
Assignments must be turned in by their due date; assignments turned in after
their due date are late. You should contact me as soon as possible if you need
to negotiate a due-date extension. The longer you wait to negotiate, the less
likely it is you'll be successful; in particular, you have almost no chance of
getting an extension if you try for one the day before the due date, and you
have no chance of getting an extention on the due date.
A late assignment is penalized five points a day for each day it's late. I use
a 24-hour clock running from midnight to midnight to measure days; note this
means that an assignment handed in the day after it's due is penalized ten
points: five for the day it was due and five for the next day.
There may occasionally be a conflict between taking a test and doing something
else, particularly among those working full time. If you're going to be out of
town, or on jury duty, or whatever, on a test day, let me know beforehand and
we'll discuss a make-up test.
A make-up test must be scheduled to be taken by the date of the test following
the missed test (or the final exam if you miss the last test). If a missed
test is not made up by the time of the next test, you get a zero for the missed
There will be only one make up given per missed test. If more than one person
misses the same test, those people will have to coordinate among themselves to
pick a mutually agreeable date for the make up.
