Network automation

source: https://networklessons.com/cisco/evolving-technologies/device-programmability

For network automation we need:

  • A programmatic interface for device configuration.
  • Separation between configuration and operational data.
  • Integrated error checking and recovery.

There are three network automation protocols that meet these requirements:

NETCONF is a protocol developed by IETF to “install, manipulate, and delete the configuration of network devices”. The goal of NETCONF is to make network automation easier. It uses XML for data encoding and Remote Procedure Call (RPC) for messages. It runs over SSH.

RESTCONF is protocol which works similar to a REST API. It maps a YANG specification to a RESTful interface and uses the HTTPS protocol for transport. You can use JSON or XML as data formats. RESTCONF is newer than NETCONF but not a replacement. It’s more of a lightweight option for engineers who are familiar with REST APIs. YANG data models can be found in the YANG git repository.
