The neutron northbound project is focused on the communication from the ODL drivers in OpenStack to the ODL neutron service and saves the neutron models into ODL data store for other providers to use. It does not include direct manipulation of low-level network/overlay elements - these are left to the providers that receive information from this project
The goals of this project are
To allow the ODL neutron service to evolve in tandem with the evolution of Neutron APIs in OpenStack.
Maintain the transparency of the current communication between OpenStack and OpenDaylight.
Improve on the current method of passing neutron information to multiple providers.
