SuPA uses a plugable backend interface to communicate with different NRMs or network elements.
Please refer to the API documentation on supa.nrm.backend for more details.
At a minimum the
deactivate() methods of the backend should be implemented,
and optionally the
topology() method to automate topology updates.
If the backend interfaces to a NRM that also can reserve network resource,
any of the other backend methods,
that match the NSI primitives,
can be implemented.
Backends are just regular Python modules.
The name of the module to be used as backend can be specified with the
backend configuration option,
.py file extention of course.
Just make sure that the the python module can be found somewhere on the PYTHONPATH.
