CNaaS Documentation

There are three parts to the documentation of CNaaS at SUNET:

  1. Product documentation - Documents the different products we use (for NMS and NAC documentation, see below)
  2. Service documentation - Documents the SUNET specific processes
  3. Customer documentation - Documents specific details of one customer implementation


As part of this project a network management system called CNaaS-NMS is being developed to automate the management of the campus networks, the software is open source and can be used by anyone outside of SUNET as well.

CNaas - NAC (Network Access Control)

In order to provide end users with an authentication mechanism CNaaS NAC was invented. It relies on freeradius ( for user authentication using 802.1X with MAB as fallback for clients not being able to use 802.1X.

Source code is available on GitHub:

Freeradius can either be integrated towards the existing user database (LDAP, Active Directory etc) or use Postgres to store credentials. CNaaS NAC provides both an API and a web interface to handle users if Postgres is chosen for storing credentials.
