Course Focus 

The course provides a basic overview of computer network architectures and protocols, with emphasis on the basic protocols used on the Internet. In the associated lab, students explore the protocols covered in class through (bi-) weekly exercises using a network of routers, switches, and Linux-based computers.

Course Prerequisites 

CMPE16 and CMPE12/L or CMPS 12B/M


Textbook: Computer Networking: A Top-Down Approach

*There are minor differences between the 5th and 6th ed., feel free to use either for class.

Academic Honesty And Integrity 

In recent years, there has been an increased number of academic integrity violation incidents in many UC campuses, and unfortunately, UCSC is no exception. The School of Engineering has a zero tolerance policy for any incident of academic dishonesty. If cheating occurs, they will result in academic sanctions in the context of the course, and in addition, every case of academic dishonesty is referred to the students' college Provost, who then sets the disciplinary sanctions. Cheating in any part of the course may lead to failing the course and suspension or dismissal from the University.

What is cheating? In short, it is presenting someone else's work as your own. Examples would include copying another student's written or electronic homework assignment, or allowing your own work to be copied. Although you may discuss problems with fellow students, when you submit an assignment with your name on it, it is assumed it is your own work. If you use ideas or text from others, you MUST cite your sources and give credit to whoever contributed to your work.

If there are any questions on what constitutes academic integrity violations, please make sure to talk to the instructor and/or the TAs for clarification. You are also referred to for additional information on UCSC's academic integrity policies.
