Course Focus


This course is an introductory look at computer communication from an engineering perspective. We focus on the principles of computer communication, and the basic concepts in the architecture of computer networks. As an introductory course, it will cover a broad set of concepts and implementations, addressing both theory and practice, but the depth of treatment is limited by the background of the students (from the prerequisites), the breadth of the subject, and the length of the course.

We use the layered model of computer communications as the vehicle for addressing computer network architecture. It starts with the physical layer and goes up through  the applications layer.  At each level we want to understand the tasks to be accomplished at that level, the goals and trade-offs made in accomplishing those tasks, the algorithms used, and the factors that relate to performance.  We also will discuss, again at a summary level, the architecture of the Internet and how the history of the voice and data networks has influenced this architecture.

Your understanding of the subject matter for this course will depend on careful reading and study of the material from the textbook, augmented by the lectures, and your work on the homework assignments and laboratory exercises.

Other courses in the networks track (CMPE 151, CMPE 152, CMPE 154, and CMPE 156) build on the basic concepts introduced in this course to provide a hands-on treatment of network administration, address in more detail the design and performance analysis of communication protocols, study in greater depth the physical layer of data communication, and offer a hands-on network programming experience, respectively.



Course Prerequisites


CMPE16, CMPE12C/12L (see your advisor for clarification)





Andrew S. Tannenbaum, Computer Networks, Fourth edition . Prentice-Hall, 2002.

Other books that may be of interest to you are:

  • James F. Kurose, Keith W. Ross, Computer Networking, 3rd edition, Addison Wesley, 2004.
  • Douglas Comer, Internetworking with TCP/IP, 3th edition, Prentice-Hall. Multiple volumes.
  • W. Richard Stevens, TCP/IP Illustrated, Vol. 1 and 2, Addison Wesley, 1994. 
  • You will probably want to read this or Comer's Vol. 1 and 2

You should review concepts of discrete probability from the textbook you used in CE16. The book Discrete Mathematics and its Applications by Kenneth Rosen, McGraw-Hill, is a good source.

Advanced material for those interested in new research can be found in conferences and journals. The best conferences in computer communication are IEEE INFOCOM, ACM SIGCOMM, IEEE/ACM Mobicom, IEEE ICNP, ACM Multimedia, ACM MobiHoc. Other good conferences include IEEE ICC, IEEE Globecom, IEEE IC3N, and IEEE WCNC.

Some of the best journals on computer communication are: IEEE/ACM Transactions on Networking, IEEE Journal on Selected Areas in Communication, ACM Wireless Networks Journal, ACM Mobile Networks and Applications, and ACM Multimedia Systems Journal.

Academic Honesty and Integrity


In recent years, there has been an increased number of cheating 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, there may be consequences within 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 process in motion. 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, your collaboration must be at the level of ideas only. Legitimate collaboration ends when you "lend", "borrow", or "trade" written or electronic solutions to problems, or in any way share in the act of writing or electronically sharing your answers. If you do collaborate (legitimately) or receive help from anyone, you must credit them by placing their name(s) at the top of your paper. 

What is Academic Integrity? This question is better answered with how we violate academic integrity. One prime example is fabrication. From the pages of the registrar:


  • In any academic exercise, submitting falsified data including bibliographic resources and experimental data, or altering graded coursework/exams and resubmitting to the instructor for a higher score.
Another example of violating academic integrity is Facilitating Academic Dishonesty:
  • One form of this is answering questions on someone else's exam or doing someone else's homework for them.
  • Another form is helping another student take a test (allowing them to cheat from you).
