Network Automation Concepts

1:29:39 Data Models in Network Automation

This section introduces data models and helps you answer these questions:

  • How should I structure the data I need to describe devices in my network?
  • Should I describe devices or should I focus on network topology and services?
  • Can I use device-level data to create device configurations while presenting high-level data models to the operators?
  • How could I describe my data models?
  • What is YANG? Why is it useful?

1:41:44 Intent-Driven Networking (2018 Edition)

Most of the intent-based systems are nothing more than a fancy orchestration system with an abstraction layer. This section describes the many levels of abstraction you can implement in such a system.
