CS 6250: Computer Networks


This project-based course will explore research topics in computer networking, prmarily at the IP layer and above. You will gain exposure to burgeoning areas of computer networking and learn how to use the tools commonly used for networking research today.


You will be expected to read 2-3 papers a week. (Reading List).
There are no required textbooks for the course.

Academic Honesty

Students are expected to abide by 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.


This class is appropriate for graduate students with previous background in networking. Some familiarity with both network programming and scripting languages (e.g., Perl, Ruby) will be helpful.


Grading will be based on three problem sets, two quizzes, and a semester-long project with a presentation and writeup. Participation will count for "fudge factors".

  • 20% Problem Sets
  • 30% Quizzes
  • 50% Project


Papers will not be handed out in class. Please print the readings and read them before class.
Please note that this schedule is tentative and subject to change throughout the course of the term.
