22 osconnector implements all the methods to interact with openstack using the python-neutronclient.
24 For the VNF forwarding graph, The OpenStack VIM connector calls the
25 networking-sfc Neutron extension methods, whose resources are mapped
26 to the VIM connector's SFC resources as follows:
27 - Classification (OSM) -> Flow Classifier (Neutron)
28 - Service Function Instance (OSM) -> Port Pair (Neutron)
29 - Service Function (OSM) -> Port Pair Group (Neutron)
30 - Service Function Path (OSM) -> Port Chain (Neutron)
