November 9, 2009 - Ten points of the final project submission is for a
performance report. What is expected for this report? How will it be graded? Let
me try to answer these two questions.
The goal in the performance report is to address the scalability of Oblivio.
Most of you will approach this as an experimental study (some of you may choose
to approach this as a measurement-based analytical study). As such, you need to
identify the factors (control variables) important to scalability, factor
levels, and response variables of interest. Then, you need to design and
describe the experiments for the factor and factor levels you identified as
important. You will almost certainly need to design and develop new (or
modified) software ("test rigs", if you will) to conduct your experiments. Don't
forget to show that your results are statistically valid. From the results you
will draw conclusions on the scalability of Oveido. One very (very!) important
thing to remember in describing experimental work (and in scientific writing in
general) is that the level of detail (in the description) must be such
that the reader can replicate your experiments. As for grading, the rubric will
be something like:
- Identification of factors, factor levels, and response variables - 2 pts
- Design of experiments - 2 pts
- Results (correct and statistically valid) - 4 pts
- Conclusions - 2 pts
If the description is lacking in detail (i.e., such that it cannot be reproduced
by the reader) you will lose points - upto 10 pts.
October 31, 2009 - CNN had an article on the 40th birthday of the
Internet -
here it is. An aritcle on a better router from one the Internet pioneers
is
here.
October 14, 2009 - The project standard has now been posted. Do you
see room for improvement to either the requirements or standard? If so, come
see me and discuss. Three-person projects are possible - to qualify for a
three person project you need to improve upon the requirements and/or
standard (and, of course, I have to approve your extended project). In
previous semesters we have had some cool extensions built by good students.
Here is a problem to think about... how could you recover messages lost when
a client is disconnected (in a compatible fashion with the standard)?
October 6, 2009 - Here below are the instructions exactly as they will
appear on your mid-term exam. What the exam will cover will be discussed in
class.
Welcome to the Mid-Term Exam for Computer Networks. Read each problem
carefully. There are eight required problems (each worth 12 points - you get 4
points for correctly following these instructions). There is also an additional
extra credit question worth 10 points. You may have with you a calculator,
pencils and/or pens, erasers, blank paper, and one 8.5 x 11 inch "formula
sheet". On this formula sheet you may have anything you want (definitions,
formulas, homework answers, old exam answers, etc.) as handwritten by you in
pencil or ink on both sides of the sheet. Photocopies, scans, or computer
generated and/or printed text are not allowed on this sheet. Note to tablet PC
users - you may not print-out your handwritten text for the formula sheet. You
have 75 minutes for the exam. Please use a separate sheet of paper for the
answer to each question. Good luck and be sure to show your work!
August 24, 2009 - Welcome to a new semester!
