 Applicability of Interfaces to Network Security Functions to Network-
                        Based Security Services
                   draft-ietf-i2nsf-applicability-00

Abstract

   This document describes the applicability of Interface to Network
   Security Functions (I2NSF) to network-based security services in
   Network Functions Virtualization (NFV) environments, such as
   firewall, deep packet inspection, or attack mitigation engines.

1.  Introduction

   Interface to Network Security Functions (I2NSF) defined a framework
   and interfaces for interacting with Network Security Functions
   (NSFs).  The I2NSF framework allows heterogeneous NSFs developed by
   different security solution vendors to be used in the NFV environment
   by utilizing the capabilities of such products and the virtualization
   of security functions in the NFV platform.  In the I2NSF framework,
   each NSF initially registers the profile of its own capabilities into
   the system in order for themselves to be available in the system.  In
