The IESG has received a request from the Operations and Management Area Working Group WG (opsawg) to consider the following document: - 'Service Models Explained' <draft-ietf-opsawg-service-model-explained-04.txt> as Informational RFC The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2017-10-11. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract The IETF has produced many modules in the YANG modeling language. The majority of these modules are used to construct data models to model devices or monolithic functions. A small number of YANG modules have been defined to model services (for example, the Layer Three Virtual Private Network Service Model produced by the L3SM working group and documented in RFC 8049). This document describes service models as used within the IETF, and also shows where a service model might fit into a Software Defined Networking architecture. Note that service models do not make any assumption of how a service is actually engineered and delivered for a customer; details of how network protocols and devices are engineered to deliver a service are captured in other modules that are not exposed through the Customer-Provider Interface. The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-opsawg-service-model-explained/ IESG discussion can be tracked via https://datatracker.ietf.org/doc/draft-ietf-opsawg-service-model-explained/ballot/ No IPR declarations have been submitted directly on this I-D.
