Advanced Computer Networks

Instructor: Brighten Godfrey
Meeting time: Tuesdays and Thursdays 3:30 - 4:45 pm
Meeting location: 1302 SC
Office hours: Tuesdays 5-6 pm, 3211 SC

TA: Giang Nguyen

Computer communication networks are among the most important and influential global infrastructures that humanity has created. CS 538 will explore the guts of the systems that have given rise to so much innovation, how networking is continuing to evolve to support new environments, and challenges in building networked systems that are simultaneously highly robust, efficient, flexible, and secure.

The course provides a foundational and current view of communication networks in order to enable students to perform high-quality research in the area. Topics will include Internet architecture and core protocols for congestion control, forwarding, naming, and routing; approaches to achieve reliability, scalability, and security; and design of data center networks, wireless networks, content delivery, and peer-to-peer networks. Material will range from the classics to the latest results, and from analytical foundations to systems design and real-world deployment.

Class sessions will combine lectures, discussions of reading, and presentations of recent research papers by students. Students will carry out a research project with the goal of publication in a conference.
