Abstract

   This document defines the framework for guiding the functionality
   provided by 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. This document provides an
   overview of how NSFs are used, and describes how NSF software
   interfaces are controlled and monitored using rulesets. The design
   of these software interfaces must prevent the creation of implied
   constraints on NSF capability and functionality.
