  • Prerequisites:

    CMPT 225 and (MATH 151 or MATH 150), with a minimum grade of C-. MATH 154 or MATH 157 with a grade of at least B+ may be substituted for MATH 151 (MATH 150).



Data communication fundamentals (data types, rates, and transmission media). Network architectures for local and wide areas. Communications protocols suitable for various architectures. ISO protocols and internetworking. Performance analysis under various loadings and channel error rates.


Computer networks and the Internet have become an essential part of our everyday life; almost every device that we use is either already connected to the Internet or soon will be. This course is an introduction to the principles and practical aspects of designing and operating computer networks as well as analyzing their performance. Special Note: Assignments will be in an online format. Lectures will all be available online after the lecture has occurred. Many lectures will also be available live/interactive at the scheduled lecture time. Students must have access to a computer with internet access, and the ability to remotely access the CSIL labs (instructions on how to do so will be provided). Some components of the course will require real-time participation during the scheduled lecture and/or exam times. Attempts will be made to schedule one or two sessions of each of these components available at times more appropriate for students in Europe and Asia (between 8AM to 8PM local time).



  • Introduction: Overview, Network types, Protocol Layers
  • Network Applications: Network applications and protocols, HTTP, DNS, Socket programming
  • Transport Layer: Transport layer services and protocols, UDP, TCP, Flow and congestion control
  • Network Layer: Routing algorithms, Forwarding and addressing in the Internet, IP, Routers
  • Link Layer and Local Area Networks: Multiple access protocols, Error detection, Ethernet, Bridges
  • Network Security: Principles of cryptography, Public key encryption, Firewalls (time permitting)



Assignments and Projects 30%; Quizzes/Midterms 40%; Final Exam 30%

Students must attain an overall passing grade on the weighted average of exams in the course in order to obtain a clear pass (C- or better).

Registrar Notes:


SFU’s Academic Integrity web site is filled with information on what is meant by academic dishonesty, where you can find resources to help with your studies and the consequences of cheating.  Check out the site for more information and videos that help explain the issues in plain English.

Each student is responsible for his or her conduct as it affects the University community.  Academic dishonesty, in whatever form, is ultimately destructive of the values of the University. Furthermore, it is unfair and discouraging to the majority of students who pursue their studies honestly. Scholarly integrity is required of all members of the University.


Teaching at SFU in summer 2021 will be conducted primarily through remote methods, but we will continue to have in-person experiential activities for a selection of courses.  Such course components will be clearly identified at registration, as will course components that will be “live” (synchronous) vs. at your own pace (asynchronous). Enrollment acknowledges that remote study may entail different modes of learning, interaction with your instructor, and ways of getting feedback on your work than may be the case for in-person classes. To ensure you can access all course materials, we recommend you have access to a computer with a microphone and camera, and the internet. In some cases your instructor may use Zoom or other means requiring a camera and microphone to invigilate exams. If proctoring software will be used, this will be confirmed in the first week of class.

Students with hidden or visible disabilities who believe they may need class or exam accommodations, including in the current context of remote learning, are encouraged to register with the SFU Centre for Accessible Learning ( or 778-782-3112).
