One example to use APONF for SAVI (source address validation improvements).

I have a suggestion to change the terminology.

For figure 1 on page 4, the "end user application" is not a good term.

I noticed that the figure in the latest PPT from Georgios and Tina, " end
user application" was changed to "network service". I think it is good.

So one page 5 of APONF problem statement draft:

"Network Management Application: Operational Support System (OSS) like
applications that help a communication service provider to monitor, control,
analyze and manage a communication network."

Could we change " Network Management Application" to "Network Service", to
be consist with the latest figure ?

In addition, may I propose we also change "Network Management Application
System" to "Network Service System" ? 

Change the definition "Network management application systems: Systems or
platforms that run the network management application."
"Network Service Systems: Systems or platforms that run the network

Best Regards,
Jun Bi

Follow-up below, expressing my understanding of further details agreed last

Procedurally: when a new service is defined, the Network Management (NM)
Application function downloads an initial network service graph to the NM
Control function. The data includes triggers for NM Control to feed back
updates to the graph. When one of these triggers is engaged, NM Control
sends back a refreshed network service graph.

Discussion Point 1: I am trying to relate this to SFC as a service. The
starting point is the Service Function Chain. This has to be translated into
one or more instances of a Service Function Path, which get passed to the
Service Classifier. Path derivation is logically something NM Control would
be responsible for. Which APONF function would be responsible for
distributing the path information to the Classifier(s)?

Discussion Point 2: to do its mapping between information gathered from
Network Elements (NE) and the network service graphs, NM Control needs a
database associating NE-provided attributes with service-specific labels.
Would downloading of such a dictionary be part of APONF responsibilities, or
would we leave creation of the database to be an operator-specific matter?

I stand to be corrected on my basic understanding of APONF operation, and
welcome comments on the discussion points.
