Re: [vnfpool] FW: New Version Notification for draft-zong-vnfpool-problem-statement-02.txt

Melinda:

Thank you for accepting my suggestion on the VNF Set information. 

I agree that it is too early to setting on a state-synchronization method or
a data model.  My question was intended to again probe the scope of the
problem to help me revise a use case draft I am working on.

The use cases within a financial world or mobile phone application systems
that back-end to VNFs systems (to perform spam filtering, DPI, or other
specific applications), will need the rapid failover.  Certain institutions
may be willing to pay for the systems that do more state synchronization and
less queries for VNF placement.  

So, with explanation may I conclude that a description of these use case fit
within the VNF Pool operation. 

If I'm unclear, please ask questions.  Our discussions work to clarify the
work.

Hi, Sue:

Thanks for continuing to review this document.  I do think that we could be
clearer about what a "set" is and what characteristics it has, and that's
something we'll work on for the next revision.

In terms of state synchronization I feel pretty strongly that it's premature
to be describing a data model.  Discussing, yes, and possibly starting to
work through, but I'd be really reluctant to commit to paper (or electrons)
in the absence of an architecture.  I certainly think we need to be talking
about metadata, first, since the functions we're talking about span a wide
range of technologies and consequently may have varying requirements.  I
think we don't have enough of a handle on the specifics of what we're doing
to do much beyond, perhaps, data structures.

Melinda
