+For the VNF forwarding graph, The OpenStack VIM connector calls the
+networking-sfc Neutron extension methods, whose resources are mapped

+- Classification (OSM) -> Flow Classifier (Neutron)
+- Service Function Instance (OSM) -> Port Pair (Neutron)
+- Service Function (OSM) -> Port Pair Group (Neutron)
+- Service Function Path (OSM) -> Port Chain (Neutron)
