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

Fri Mar 23 11:00:21 EDT 2012

Hi Jerry,

Regarding high-level paper I agree, yet the protocol life cycle is quite important in NSI context. I would not go into too much details, that’s why I proposed to do so as an example on success scenario (so we can skip some states or more complex transitions). I support GLIF Automated GOLE efforts to be included. We can put it into demo and lessons learned sections, unless you prefer to make separate section for deployment (well, demos were deployments of prototypes, that’s why I would put it there).

Showing community support is as well good idea. I am not sure, but maybe future work is the right place to put it. What do you think?

Best regards

Radek

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

Dear all,
The deadline for TNC12 full paper is 16 April, so we don't have too much time (as usual). In the attachment I've placed a drafted template for this article, based on TERENA template. I would like to follow below schema:
- ask yourself if you want to contribute to the paper :) - deadline ASAP
- Browse attached ToC and see what and where you can contribute, please update ToC if you feel there is something missing and you may fill it - deadline - Wed 28.03 (we can finalize that via email on during NSI call)
- People will be assigned to particular sections based on expressed interest - Thu 28.03
- Drafted contributions delivered - Fri 06.04
- Finalization on the paper - by Fri 13.04
- Paper submission - Mon 16.04

Comments are more than welcome. I'll take care of merging contributions and take care of formatting and versioning. I suppose we could use NSI forge to place docs in one place. 

Best regards
Radek
