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) |
