INFO5197 : CR18: Network Measurements

Network measurements enable operators and practitioners to better study the networks they manage and investigate. Unfortunately, the complex ecosystem that is today’s Internet, makes it necessary to master a large variety of techniques and tools to study our networks. Ever growing network speeds, encryption, and heterogeneous access technologies are just some of the challenges that increase the complexity of this task.

This course aims to introduce students to the art of network measurements across the variety of techniques that are used to collect and interpret information from the network and the traffic that travers it. From switches and routers, to user space and wireless links, the students will learn the challenges that arise when collecting traffic information at different levels of the network. Next, the course will introduce the students to different techniques used to interpret the collected information and transform it into actionable knowledge.

Covered topics:

• Concepts of network measurements
• Active and passive measurements
• In network telemetry and sketches
• User space packet processing
• Wireless network measurements
• Machine Learning based inference
