Despite their wide availability, operators report persistent challenges in operationalizing these abstractions in a consistent, scalable, and automatable manner. This document describes the problem space for the ONSEN Working Group, identifying the operational gaps and deficiencies in existing IETF service and network abstraction models that prevent effective end-to-end automation. The problems documented here are drawn from operator experience and from the findings of the IAB NEMOPS Workshop. This document does not propose solutions, protocols, or new data models.}, }
