Dynamic Configuration of Devices and Services with ONOS
Participating Organizations
Configuration of Devices ● Goal is to enable a network operator to seamlessly configure devices from different vendors and to verify the configuration ○ With minimal or no human intervention
● Offers significant OPEX savings and vendor independence for network operators ● Offers vendors faster integration of their products into operator’s networks

First, ONOS NB receives device config data as JSON or XML, decodes it and stores it in the distributed store.

Afterwards, ONOS SB receives change notifications and encodes the data to JSON or XML and conveys it to the device.
Configuration of Services ● Goal is to enable a network operator to seamlessly configure and provision a service on the network comprising many devices from many vendors ○ With minimal or no human intervention
● Provides network operators with agility to deploy new services with reduced OPEX ● Offers vendors opportunity to support many services on their devices

Service design creates a YANG model for the service. The model gets compiled and registered; either a priori by the user or at run-time by the application.
