Criteria for Evaluating AAA Protocols for Network Access

RFC 2989         Network Access AAA Evaluation Criteria    November 2000


   This document summarizes the requirements collected from those
   sources, separating requirements for authentication, authorization
   and accounting.  Details on the requirements are available in the
   original documents.

1.  Introduction

   This document represents a summary of AAA protocol requirements for
   network access.  In creating this documents, inputs were taken from
   documents produced by the NASREQ [3], ROAMOPS [2], and MOBILEIP [5]
   working groups, as well as from TIA 45.6 [4].  This document
   summarizes the requirements collected from those sources, separating
   requirements for authentication, authorization and accounting.
   Details on the requirements are available in the original documents.

1.1.  Requirements language

   In this document, the key words "MAY", "MUST, "MUST NOT", "optional",
   "recommended", "SHOULD", and "SHOULD NOT", are to be interpreted as
   described in [1].

   Please note that the requirements specified in this document are to
   be used in evaluating AAA protocol submissions.  As such, the
   requirements language refers to capabilities of these protocols; the
   protocol documents will specify whether these features are required,
   recommended, or optional.  For example, requiring that a protocol
   support confidentiality is NOT the same thing as requiring that all
   protocol traffic be encrypted.

   A protocol submission is not compliant if it fails to satisfy one or
   more of the MUST or MUST NOT requirements for the capabilities that
   it implements.  A protocol submission that satisfies all the MUST,
   MUST NOT, SHOULD and SHOULD NOT requirements for its capabilities is
   said to be "unconditionally compliant"; one that satisfies all the
   MUST and MUST NOT requirements but not all the SHOULD or SHOULD NOT
   requirements for its protocols is said to be "conditionally
   compliant."
