[Nsi-wg] SC demos

Hi all-

Things have been very disorganized the last few weeks regarding the 
demos.   I have been distracted on some other issues and am sorry about 
this.  But this is the situation:

The NSI version2 implementations are not all ready.   And some key GOLEs 
will only have V1 available, or will not be able to perform aggregation 
functions,...  and the status monitors will also need to be able to deal 
with two versions...  And no doubt there will be some technical issues 
we'll need to iron out as we implement and test...  so I think a 
comprehensive NSIv2 over the Automated GOLE fabric is going to have to 
be re-thought...

I think it is just not realistic to have the AutomatedGOLE running V2 
everywhere, and even more unlikely we would be able to have them both 
*interoperating* at this time.


However...  all is not lost...

We should keep in mind that what we want to demonstrate and promote at 
SC is *_/*NSI*/__/*and [automated] GOLEs*/_* - not specifically v2 per 
se, although it would be nice.   But our priority should be to 
demonstrate and promote a _/global NSI as the ubiquitous 
protocol/_...with many implementations, and its features where they are 
ready.   Remember, many of the folks at SC have only just heard of NSI 
and need basic high level vision, status, and roadmap - not details 
about state machines or topologies, or even I suspect will they need to 
see a Modify() primitive actually work:-)   Besides, the differences 
between v1 and v2 are largely internal advances and do not much present 
new capabilities to the end user.

So if we keep this Big Picture perspective for SC12, I think we can 
still have a very powerful NSI + AutoGOLE demonstration despite the 
varying degrees of readiness for v2...
     ---> NSI as the common ubiquitous automated provisioning 
framework/protocol, and
     ---> Open Lightpath Exchanges (and "distributed" exchanges) as the 
emerging global transport architecture,
     ---> And the AutomatedGOLE Fabric running NSI is an existence proof 
and test facility for early adopters.

So I would like to propose we take the following tact for SC:

- We leverage the NSI "service definition" concept.. We define "ets" 
services as v1, and we define a new set of service domains called "etsv2".

- We preserve the AutoGOLE running NSIv1 as-is using vlans 1780-1783.  
THis will allow us to show NSI running using the status displays we have 
already working.

- We establish a second "etsv2" service plane consisting of NSIv2 
domains - these will get VLANs 1790-1799.

- Even if the ETS and ETSv2 domains cannot interoperate at the protocol 
layer, they can still interconnect at the data plane layer.   One domain 
would simply be the "static" client of another... For instance, we can 
have the ETSv2 domains act as end systems on the edge of a ETS (v1) 
domain,  and we set up vlans across v1 to serve the v2 domain SDPs.  
THis is a tunneled strategy, but it would be interesting to show the 
capability none-the-less.   THis would then allow both V1 and V2 
provisioning demos to occur simultaneously.

- or We could also/instead simply manually configure the 1790-99 VLANs 
across the AutoGOLE between the V2 domains.  THis would also allow both 
V1 and V2 provisioning demos to occur simultaneously.

- We define the topologies accordingly.

This would allow us to have both versions running in parallel, even if 
they do not interoperate at the control plane.   And frankly, its a good 
migration strategy to v2 in the AutoGOLE rather than a flag day.   This 
allows those implementations that have v2 to demonstrate v2 albeit in a 
somewhat constrained manner...  But We can still explain the development 
status and roadmap for the next several quarters.   And we can still 
present the NSI capabilities and vision and active Workging Group...

If the current Huricane sitting on top of me does not take me off the 
air, I will try to put a couple slides out to the lists to 
diagramtically explain this...

Thoughts?

Best regards
Jerry
