Learning Outcomes for Module 3 – In Network Monitoring, Caching and Control (DVAD43)

April 25 – June 5, 2022

During the last six weeks, the focus will be on applying data plane programming and P4 to advanced network monitoring, network caching and network based control. You will both read about theoretical aspects of network monitoring P4 and practically learn how to implement them in P4. This will help you to generate new ideas in how to apply P4 to create advanced network monitoring solutions using programmable data planes.

Week 1: 25/4-01/05/2022

Standard documents

Link to the In-band Network telemetry (INT) specification.

  • v2.1 [PDF] (May 2020)
  • working draft: [MDK]

There are multiple elements involved in the INT:

  • INT sources: Add telemetry instruction headers
  • INT intermediates: receive packets with INT instructions headers, act accordingly and add telemetry headers that contain telemetry data according to the telemetry instruction headers
  • INT sink: remove telemetry headers and send INT reports to INT collector nodes
  • INT collector nodes: receive and parse INT reports for further analysis, machine learning, visualization

This directory contains all of those standards.
