Hey community,

I'm currently trying to figure out how the relation between the configurational and the operational datastore. I have an assumption I would like to verify by asking you. It is depicted by the attachted picture I created.

What I understand is, that

  • ODL retrieves information about the network infrastructure and creates a model of it in the operational datastore.
  • This model can be accessed by applications by using a read transaction on said datastore.
  • Any changes can be written into the configurational datastore by using a write transaction.
  • ODL will automatically execute said changes to the network

Then the cycle repeats.

Is this how this works? If not, please let me now where I am wrong.

Many thanks and a good day to you all!

In yang data model, the config data is supposed to be entered by network administrator. So it is readable and writable. For example, the host name of a linux machine.

The operational data is just some piece of runtime generated data such as CPU utilization, which can only be read, not writable.
