                NSF-triggered Traffic Steering Framework
               draft-hyun-i2nsf-nsf-triggered-steering-02

Abstract

   This document describes an architecture of the Interface to Network
   Security Functions (I2NSF) framework which enables traffic steering
   between Network Security Functions (NSFs) for security policy
   enforcement.  Such traffic steering enables the composite inspection
   of network traffic by steering the traffic through multiple types of
   security functions according to the information model for the NSF-
   facing interface in the I2NSF framework.  This document explains the
   additional components integrated into the I2NSF framework and their
   functionalities to achieve NSF-triggered traffic steering.  It also
   describes representative use cases to address major benefits from the
   proposed architecture.
