Course description: This course covers the techniques needed to understand and analyze modern data communications networks using a top-down, layered approach to computer networking. It covers the basic architecture of packet networks and their network elements and the protocols used to enable transmission of packets. This is a project oriented undergraduate course. Students will be introduced to various tools for simulating communication networks such as ns-3 and Riverbed Modeler (formerly OPNET from OPNET Technologies). Laboratory work is included in this course.

Pre-requisites: Successful completion of ENSC 327-3 or permission of the instructor.
Note: ENSC Undergraduate Curriculum Committee (UCC) does not permit enrollment in ENSC 427 if you have not successfully completed ENSC 327.
