Hi Alan,

We are now in the process of doing It :)

Thanks

Hi Alan,

We have also proposed an idea about SFC.
For more details you can refer to https://review.openstack.org/#/c/146315/


Thanks
Vikram

The current model and implementation leverage the Neutron services as is (the model is actually agnostic of the service definition/implementation). Will be happy to further discuss this, feel free to ping on #openstack-gbp.
