Abstract

   This document describes the framework for the Interface to Network
   Security Functions (I2NSF), and defines a reference model (including
   major functional components) for I2NSF. Network security functions
   (NSFs) are packet-processing engines that inspect and optionally
   modify packets traversing networks, either directly or in the
   context of sessions in which the packet is associated.
