Data Networks, ICS 451

This page is subject to change without notice -- please reload it in your browser if an item that might affect you may have changed.

The organization of the course is described here. Please review it at the beginning of the course and occasionally during the semester. It includes information about course goals, class time and location, contacting the instructor, office hours, the textbook, grading, and the no cheating policy.

If you have any questions, please contact the instructor.

Schedule

This course is loosely based on the same course taught in the Fall of 2004. If you wish to look ahead, please refer to that course, though since technology has evolved, the course contents will have some differences.

Presentation notes are in HTML. I usually post notes no later than the day before the lecture.
