             I2NSF Registration Interface Information Model
             draft-hyun-i2nsf-registration-interface-im-04

Abstract

   This document describes an information model for Interface to Network
   Security Functions (I2NSF) Registration Interface between Security
   Controller and Developer's Management System (DMS).  The information
   model is required to support NSF instance creation, registration, and
   deletion request via the registration interface.  This document
   explains the procedures over I2NSF registration interface for these
   functionalities.  It also describes the detailed information which
   should be exchanged via I2NSF registration interface.

1.  Introduction

   A number of virtual network security function instances typically
   exist in Interface to Network Security Functions (I2NSF) framework
   [RFC8329].  Since these NSF instances may have different security
   capabilities, it is important to register the security capabilities
   of each NSF instance into the security controller after they have
   been created.  In addition, it is required to instantiate NSFs of
   some required security capabilities on demand.  As an example, if
   additional security capabilities are required to meet the new
   security requirements that an I2NSF user requests, the security
   controller should be able to request the DMS to instantiate NSFs that
   have the required security capabilities.
