The Group Based Policy framework complements Neutron by defining policies that can be applied between groups of endpoints for broader, more diverse network services beyond basic connectivity. These services are expressed as policies that allow application administrators to delegate networking requirements to groups of endpoints.
The Group Based Policy framework is not yet the default application-centric policy abstraction for Neutron though, Dvorkin notes.
"The beauty of the open source is that the best or, at least, the most adopted approach will eventually win," he says. "So, time will tell. However, we do hope that GBP will become the default application-centric policy abstraction for Neutron, and we'd be glad to evolve it in any way that would make it more useful and adoptable."
With regard to the OpenStack Congress declarative compliance and governance cloud policy framework currently under development, the Group Based Policy framework for Neutron will be utilized by Congress for application-centric network policy definition, abstraction and enforcement, developers say. It will also be utilized in the Data Services Engine (DSE) of the OpenDaylight open source SDN project, they say.
"It provides a framework by which compliance and governance systems like Congress can issue directives that can affect how policies are applied without change of intent," Dvorkin says.
OpenDaylight DSE was recently demonstrated by Plexxi as a way to refresh configuration data when changes occur.
