CPSC 441: Computer Networks

Professor Carey Williamson

Fall 2021

Tutorials

The tutorial sessions in CPSC 441 will provide supplementary material to augment the lectures. In general, the tutorials will cover material in more depth than is possible in class, and will focus on real-world networking protocols. Most tutorials will present additional examples to reinforce the concepts and principles covered in lectures (e.g., HTTP RFC 2616, TCP RFC 791, IPv6, Ethernet LANs). Some tutorials will provide specific assistance with assignments (e.g., socket programming, HTTP servers, WireShark, help sessions), while others will be used for demos and grading of assignments. A few tutorials may cover new material that does not fit within the lecture time slots available (e.g., Internet history, network security, transmission media). Others will review material and offer study tips in preparation for exams.

Attendance at CPSC 441 tutorials is not mandatory, but is highly encouraged. The TAs are there to help you learn and apply the material covered in the course, especially that related to the programming assignments. Regular attendance at tutorials and a solid effort on your part will help ensure your success in the course!
