Technical Summary
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 models that are
not exposed through the Customer-Provider Interface.
Working Group Summary
There was debate on the "network service model" concept in RFC 8199 .
This was solved by coordinating the cross WG discussion with NETMOD
during both the WG adoption call and WG LC.
Document Quality
This document has received extensive input and review. It has already
been used to direct L2SM and L3SM work.
One of the authors of a closely related document RFC8199 (Benoit Claise)
reviewed this document and provided very useful comments, to align the
document and terms -- there have been integrated. Much
of the discussion is somewhat over my head, and so I'm relying on his
expert opinion.
