Other Recommended Texts:
Computer Networking II builds upon Computer Networking I. The course will cover areas of computer networking that were not treated in any depth in Computer Networking I. These include:
The project and homework portions of the course complement
the lecture material are intended to help deepen your understanding of
the field.
Students are expected to have a solid grasp of the fundamentals
of computer networking, including a basic understanding of the TCP/IP protocols
and sockets programming, as given in CS 3251. Knowledge of "C"programming
is essential in order to complete the two projects.

Note: Essentially everything in the schedule is subject
to change. Specifically, we may not be able to cover all topics in the
time available.
A project will be done in each half of the semester. The first-half project will be to simulate a local area network and measure its performance. The second half project will be to design and implement an on-line trading system. The project will build on the sockets programming that you did in Computer Networks I. This project will be done in groups. The project will result in groups conducting a live trading session over the Internet. The project and homework portions of the course are intended to help you apply your understanding of computer networking theory and protocols, and are an integral part of the learning process.
Grades will be assigned based on the midterm exam (30%),
two projects (30%), and the final exam (40%). There will be approximately
four homework assignments. Answer sheets will be given for the assignments
and no grades will be allocated for them.
You are expected to familiar with the academic honor code (as set forth in the Georgia Tech honor code. Honest and ethical behavior is expected at all times. All incidents of suspected dishonesty will be reported to and handled by the office of student affairs. You are to do all assignments yourself, unless explicitly told otherwise. You may discuss the assignments with your classmates, but you may not copy any solution (or part of a solution) from a classmate.
You are encouraged to help one another via the newsgroup,
with questions that deal with the language or infrastructure. For example,
"how do I compile with library X" or "why does the compiler complain about
a type mismatch in this fragment of code...?" or "how do I access the third
byte of an int?".
