[Nsi-wg] Full paper on NSI for TNC12 conference

[Jerry Sobieski]

Hi Radek-
I am willing to help on this...  Some thoughts:

In the "current" section (v1.*)...
I would suggest this be a relatively high level paper - not getting into 
the specifics of WSDLs or state machines (too much detail)- but keeping 
to the higher layer inter-domain purpose for NSI, its technology 
agnostic approach - how that works and what that brings, the connection 
life cycle, basic primitive functions, the service tree and tree/chain 
processing, scheduled and on-demand, integrated AAI for every 
interaction, the NSI topology model, and the strategies (such as 
security and scalability) that helped define how these features were 
implemented.  (This paper should entice readers to learn more - not 
teach them all the dirty details:-)

We should put a section in to describe the GLIF Automated GOLE effort 
that has deployed NSI and has learned a great deal in doing so - where 
it functions well, where we had problems, etc.   The point of this 
section is to show that NSI is not simply a chalk board exercise, but is 
being tested in the field and experience feeding back directly into the 
protocol and standard.

Given that we have some clarity now on version 2.0, we should (IMO) 
include a brief high level summary of those features and why they are 
important in the "futures" section.  I would also include the drive in 
the working groups towards a common topology model (i.e. NML), ongoing 
work on a common topology distribution process, work going on in GLIF to 
find a comprehensive NSI conformant performance verification model, etc 
... (Jeroen and I will be presenting a paper on topology issues, so we 
don't need a lot of detail on this topic here - just enough to show that 
NSI sees a broader picture than simply the CS provisioning protocol.)

I don't know where is best, but it would be useful also to indicate 
which organizations have expressed a commitment to deploying NSI based 
services in their networks.   Certainly some have committed to doing so, 
and other have gone a step further with estimated deployment 
timelines...  Presenting this commitment is an important aspect to 
campus or regional CIOs etc that are wondering about future directions.

Finally, I think it is important (especially to the "suits" attending 
TNC) to emphasize the Open international process for the NSI work and 
the community consensus building that this engenders - resulting in 
broader adoption -> which is critical for global functionality in an 
inter-domain services world.  (We are not just addressing networking 
organizations, but increasingly IT organizations...)

...just some ideas...
Jerry
