Finalité

The goal of this course is to present new technologies designed for advanced operations of IP networks in the last twenty years. The course starts with the evolution of IP switching and routing architectures, with a particular focus in traffic engineering and quality-of-service architectures. Then, the evolution of the Ethernet architecture and layer-2 protocols in general is presented, showing the extensions applied to let layer-2 protocols scale going from local area to metropolitan and data-center network segments. The course shows how IP and Ethernet evolutions recently converged in novel softwarized network environments, making use of data-plane programmability, network virtualization, cloud-native systems and automation frameworks.
