Exactly, this was what I stressed in the today’s meeting, to clarify the difference between the model which is used between customer and service orchestrator and the model used between OSS/BSS and network orchestrator. Even the model used between customer and service orchestrator and the model used between service orchestrator and network orchestrator doesn’t need to be same.

Have a look at Figure 3.

That is, the draft you point at has a far wider scope and purpose. No problem with that. Doing our work in L3SM we repeatedly encountered confusion about what a service model is and where it fits in the "hierarchy". So we wrote some text. Looking at our draft and Figure 1 in the yang-model-classification there is not complete coherence. Which way would like to go forward? Roll our text into yang-model-classification? Push forward separately? Adrian From: OPSAWG [mailto:[email protected]] On Behalf Of Benoit Claise Sent: 19 July 2016 09:18 To: Qin Wu; [email protected]<mailto:[email protected]> Subject: Re: [OPSAWG] New Version Notification for draft-wu-opsawg-service-model-explained-00.txt Qin, Explaining the difference between a service and network element YANG modules is the objective of https://datatracker.ietf.org/doc/draft-ietf-netmod-yang-model-classification/ Abstract The YANG [RFC6020] data modeling language is currently being considered for a wide variety of applications throughout the networking industry at large. Many standards-defining organizations (SDOs), open source software projects, vendors and users are using YANG to develop and publish YANG modules of configuration, state data and operations for a wide variety of applications. At the same time, there is currently no well-known terminology to categorize various types of YANG modules. A consistent terminology would help with the categorization of YANG modules, assist in the analysis the YANG data modeling efforts in the IETF and other organizations, and bring clarity to the YANG-related discussions between the different groups. This document describes a set of concepts and associated terms to support consistent classification of YANG modules. Regards, Benoit Hi, We have submitted a new I-D that discusses the scope and purpose of service models within the IETF and describes how a service model can be used by a network operator. https://datatracker.ietf.org/doc/draft-wu-opsawg-service-model-explained/ In addition, this draft clarifies the role and position of service model in the SDN architecture and Clear several misconception on the service model. Your questions and comments are welcome.

Name: draft-wu-opsawg-service-model-explained Revision: 00 Title: Service Models Explained Document date: 2016-07-05 Group: Individual Submission Pages: 12 URL: https://www.ietf.org/internet-drafts/draft-wu-opsawg-service-model-explained-00.txt Status: https://datatracker.ietf.org/doc/draft-wu-opsawg-service-model-explained/ Htmlized: https://tools.ietf.org/html/draft-wu-opsawg-service-model-explained-00 Abstract: The IETF has produced a considerable number of data models in the YANG modelling language. The majority of these are used to model devices and they allow access for configuration and to read operational status. A small number of YANG models are used to model services (for example, the Layer Three Virtual Private Network Service Model produced by the L3SM working group). This document briefly sets out the scope of and purpose of an IETF service model, and it shows where a service model might fit into a Software Defined Networking architecture or deployment. Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.
