Dear Rakesh,

After a second read, I think this email is very clear and worth to post to list so that to answer Warrant’s question about scope.

Regards,
Will LIU (Shucheng LIU)

Hi Will,

My apologies for late response.

Like you mentioned there are two set of interfaces as shown in the draft:


1.       Client/Northbound interface to allow unified access to address management system (CASM). This should be RESTful interface with YANG data model.

2.       Addressing function/Southbound interface to get/update address records. This could be protocol or RESTful interface but in my opinion, it is better to do RESTful interface so that existing system (standard-based or proprietary) could implement CASM defined interface on top of these functions to integrate with “CASM”.

I hope this gives us a very clear charter.

Thanks
Rakesh

Subject: notes from my side

Sorry that due to my pc, I missed some. Here is what I have, hope can help Adrian:


Attendees: Adrian Farrel, Chen LI(China Telecom), Declan Ma(ZDNS), Ignas Bagdonas, Laurent Ciavaglia(AL/Nokia), Ralph Droms,  Ying CHNEG(China Unicom),Will LIU(Huawei), Tony Peng(Huawei)

Will: Unfortunately neither Rakesh from Juniper nor Chongfeng from CT can join us. However, we can use the framework draft to show their ideas, which is the interface or interfaces they want to standardize, and what are the scope. IMOH, in Rakesh draft there are two interfaces, NBI and SBI. Chen, please let them know how is your prototype working with these two interfaces.

Chen LI: SBI - netconf with YANG models, connecting three vendors develop;
NBI - restful , connecting with APP, now only one APP, but the system can connect to multiple, such as OSS, orchestrator.

Regards,
Will
