Hi Robert
Yes.. I agree that VPN usecase can evolve to SPMC 
(single-producer-multiple-consumer)..
And yes, we should have a way to support SPMC even when we use external 
datastore..
However I think that support of SPMC can be taken up a next step / 
phase2.. 

With regards
Ashutosh

That depends on what is actually in the deployment: once the routes are 
ingested they can act as input into multiple use cases.

Restricting the data flow to 1:1 really means that we will prescribe how 
outputs can be consumed -- leading to a deployment where each use case is 
an integrated silo with little to no flexibility.

Now if the deployment calls for both processing BGP routes *and* 
maintaining VPNs in the underlying network, what is SPSC in the component 
use cases becomes MPSC...

Bye,
Robert

 Hi guys,
  I'm soliciting for help since I'm not sure how to update bundles with no 

affection for services (such as In-Service Software Upgrade ).

 For example: bundle A 1.00.11 needs to be updated from bundle A 1.00.10. 
During such process, if there is any mechanism to ensure that no affect 
will occur on the bundle A?s normal service in ODL !

 Are there any documents which can help me to know? Thanks?
 

 Best wishes!
