Advanced Topics in
Communication Networks Fall 2024

Networked Systems Group

This course covers advanced topics and technologies in computer networks, both theoretically and practically.

The goal for this course is to provide students with a deeper understanding of existing and upcoming Internet routing and forwarding technologies used in large-scale computer networks such as Internet Service Providers (e.g., Swisscom or Deutsche Telekom), Content Delivery Networks (e.g., Netflix) and Data Centers (e.g., Google).

Besides covering the fundamentals, the course will be “hands-on” and will enable students to play with the technologies in realistic network environments, and even implement some of them on their own during labs.
