A very enjoyable graduate level course. the subject matter is so advanced that there are no textbooks yet. reading material is just plain text RFCs. Lixia Zhang even wrote some of them. Grading a little odd.

Learning networks from Prof.Zhang is pure pleasure. She is extremely knowledgeable and has been there done that. She is also concerned about student understanding and wont hesitate to repeat entire lectures if she finds that students are struggling a little with certain topics. The course is fairly heavy though not overly so. If you read the RFCs and lecture slides she posts, you will have no problem with the course. It is the kind of course that motivates you to learn more about networks. She is super busy though so dont expect your quizes to be graded in time. But when she is available, she wont blow you off if you go to her during office hours. Do try to attend her classes. They are definitely worth it.
