Information Model of NSFs Capabilities
draft-ietf-i2nsf-capability-00.txt
Abstract
This document defines the concept of an NSF (Network Security
Function) Capability, as well as its information model. Capabilities
are a set of features that are available from a managed entity, and
are represented as data that unambiguously characterizes an NSF.
Capabilities enable management entities to determine the set offer
features from available NSFs that will be used, and simplify the
management of NSFs.
