I have to say this draft seems like a step backwards.  The value of yang is you 
can focus on information elements and desired transactions, and then matching 
it to (standard) encoding, transport, security, etc that best matches your use 
case.  This approach, as you know, is standardized and in use by many (I'm 
including gNMI).

I don't see a basis for not just defining a yang model with an example or even 
suggested, encoding/transport/sec for your use case.

I hope you address why the existing yang/xxx-conf standards are insufficient 
and why your approach is a substantive improvement in your upcoming 
presentations and document revisions.

Thanks,
Lou

One thing I missed in reading this draft is why this was better than existing 
tools, e.g. YANG over RESTCONF.  For which we know the integration with the 
rest of the operational environment.  (I can believe there is an advantage, but 
I couldn't tell what it was.)

Hi,


Recently, the industry has witnessed increasing use cases where a controller 
needs to install ephemeral routing states in the network. Protocol use requires 
the controller to implement laborious encoding, decoding, serialization of data 
streams, etc.



We have written a generic draft of routing RPC API for programming ephemeral 
routing states, using SR policy programming as an example.

https://datatracker.ietf.org/doc/draft-ali-spring-sr-policy-programming-rpc/.

It aims to ease the programming of ephemeral routing states in the network 
using an SDN controller.



We request a review and discussion on how to forward the work to the IETF. We 
will present it at the upcoming RTGWG meeting.



Thanks
