            I2NSF Consumer-Facing Interface YANG Data Model
            draft-ietf-i2nsf-consumer-facing-interface-dm-04

Abstract

   This document describes an information model and a YANG data model
   for the Consumer-Facing Interface between an Interface to Network
   Security Functions (I2NSF) User and Security Controller in an I2NSF
   system in a Network Functions Virtualization (NFV) environment.  The
   information model defines various managed objects and relationship
   among these objects needed to build the interface.  The information
   model is organized based on the "Event-condition-Event" (ECA) policy
   model defined by a capability information model for Interface to
   Network Security Functions (I2NSF)[i2nsf-capability-im], and the data
   model is defined for enabling different users of a given I2NSF system
   to define, manage, and monitor security policies for specific flows
   within an administrative domain.
