Syllabus
Meeting times and place
The class meets Tuesdays and Thursdays, 9:30 - 10:45, in ME 214. It is also offered over ITV at various locations.
Class description
The short course description from the CS department web site:
A theoretical and practical study of computer networks, including network structures and architectures; protocols and protocol hierarchies; error handling; routing; reliability; point-to-point networks; broadcast networks; local area networks; efficiency and throughput; communications technologies; case studies.
There will be a couple of programming assignments. You need to be able to program in C or C++ in a Unix-like environment, such as Linux, to successfully complete these assignments.
Office hours
I have an office in Farris Engineering Center 342 and will be there most Tuesdays and Thursdays. I'll have office hours there right after most classes, but talk to me, if another time works better for you.
Our teaching assistant, Hongwei Wang (hongwei@unm.edu), has office hours on Wednesdays from 2:00 to 4:00 in his office in FEC 126.
Contacting me
The best way to reach me is via riesen@cs.unm.edu.
Mailing list
Sign up for the class mailing list. I will use it to send out announcements. We all can use it to discuss topics relevant to the class.

Missed classes
If you miss a class, it is your responsibility to catch up. Use the class web page, talk to your colleagues, and watch the video recording. Email me if you have questions, but use these other resources first.
I will post the slides for each class on this web page. I'll try to have them up the evening before class. The final version that I actually used in class will be posted in the afternoon after class.
Academic honesty
The university rules for academic honesty and plagiarism apply. I will not tolerate cheating. If you have problems following the class or doing the assignments, come talk to me.
