5. Course Admin • Office Hours • General Rule: If it’s not during scheduled office hours,or if you don’t have an appointment….. I’m not in. • Hao Che’s Office Hours (NH 325) • Tuesday and Thursday: 12:30pm – 1:50pm • or, by Appointment (i.e. a time scheduled in advance)

6. How to Take this Course? • Don’t assume the instructor has answers to all the questions • The instructor will cover only the general aspects of networking • You need to be self-motivated and find answers on specific topics by yourself and share them with others (meaning you have to do a lot of homework although no homework is assigned) • There is no textbook for this course. You need to search for references by yourself, as part of the homework
