Hi Guy and Jens-
While I might agree that the a "simmer" period is warranted to implement
and deploy these NSI based services, I would strongly recommend against
shutting down the WG. I think there are some important topics the
protocol discussions need to take over the next year.
One obvious topic being the multipoint services. Another would be a
symetric protocol implementation that can more easily support
unsolicited messaging between NSAs. Asymetric connections. And I know
there are other issues to be revisited or proposed.
And this leads us into another interesting proposition: If NSI is
indeed a general provisioning protocol - it builds Connection objects
now as technology agnostic service definitions - why could we not extend
it to do other types of service definitions?... say a Switching Point
service object that could provide a means of doing technology agnostic
mp services? Or even a Compute Node object that could offer yet a
different type of services. These all interlock using Service
Termination Points. I think this is entirely feasible - and I could
offer the GTS API an example of working code. GTS uses NSI, and NSI
does some important heavy lifting for GTS. But the GTS API and the NSI
API are almost exactly the same (!) The NSI protocol could be extended
to support these additonal types of service objects quite easily IMO.
We are so(!) close with both NSI and GTS...it would be a shame to not at
least look at the prospect.
I apologize for not being more active in the NSI-WG recently, but I
would like to request an opportunity to present this NSI+GTS prospect to
the WG before we go into simmer mode...
Could we do this?
Thanks
Jerry
