Detailed Schedule & Syllabus

NOTE: This schedule is TENTATIVE, and may change as certain topics may end-up being harder or easier than anticipated. Changes to the schedule will be reflected as quickly as possible on this page.

The different columns in the schedule are as follows:

• The Scope column provides a brief description of the material to be covered in each lecture.
• As its name indicates, the Reading Assignments column identifies what you need read ahead of the corresponding lecture. It usually consists of chapters or sections in the textbook, or some external material from IETF RFCs. It also includes optional reading material (in the line starting with "FYI") that can provide additional useful insight into the topic at hand.
• The Slides column gives a pointer to the set of slides (in PowerPoint format) that will typically be covered during the lectures. The slides also include some useful exercises to test understanding of the material they cover.
• The Review Questions column provides pointers to review questions (in MS Word format) that need to be handed-in at the start of the corresponding class and that are based on the reading material for the class. Review Question i is due at the beginning of Lecture i.
• Finally the Labs/Quizzes column identifies dates when either quizzes will be given at the start of class (blue-colored entries), or when labs are due (green-colored entries).
