IC522: Computer Networks (Spring 2017)


Instructor:
Kyung-Joon Park
Office hours: By appointment, E3-513 DGIST

Textbooks:

  • Computer Networking: A Top-Down Approach Featuring the Internet, by J. Kurose and K. Ross, Addison-Wesley
  • Suggested additional references:
    • Larry L. Peterson and Bruce S. Davie, Computer Networks: A Systems Approach, Morgan Kaufmann Publisher
    • D. Bertsekas and R. Gallager, Data Networks, 2nd Edition, Prentice-Hall, 1992 (freely available at http://web.mit.edu/dimitrib/www/datanets.html).
  • Introduction to queueing theory
    • The ppt slides for queueing theory lectures are available here

Course Description:
We will discuss various issues on computer networking in a top-down manner, by beginning at the application layer and moving towards the physical layer as in the main textbook. We will also cover basic concepts of queueing theory to have an ability to analyze packet networks. In addition, we will read several key research papers to deal with the state-of-the-art research on computer communication and networking areas. If time permits, we will carry out a research project to have a hand-on experience in computer networking systems and to understand how they work in an algorithm level.

Grading:
30% - Midterm exam
40% - Final exam
30% - Homework

Announcement:

  • The midterm exam is scheduled at 1:30 pm, April 20 (Chapter 1 & 2 and Queueing will be covered.)
