CPEG 419/CISC 450 Fall 2015
  • Textbook: 6th editioon of Kurose and Rose. Computer Networking. This book is required
  • Prerequisites: Introduction to probability, C/C++ programming, abaility to use VMware or cloud
  • Grading (subject to change): homework homework=20%, projects=25%, midterm=20%, final=25%, forum and class discussion, 10%. .
  • Homework must be turned on online
  • While not required, a laptop is useful.
  • Most lectures are also availabe in video online. But these videos are fast paced. See video on how to watch videos lectures. Also, the material covered in class is not exactly the same as the material covered in the videos.
  • All homework and projects should be turned in via email and include your name in the file name and on the homework and projects.

 

 
Objective: To gain an understanding of how the Internet works. Understand a select set of protocols from the OSI (or TCP/IP) protocol stack, understand the principles of protocol, understand basic protocol performance analysis. To be able to use sockets to exchange data on the Internet. To gain preliminary understanding of distributed systems.
