The intention is to present a detailed-level list of the summarized requirements in [1] as well as including some important requirements from [2,3, and 4]. 4. Introduction This document is a common list of accounting requirements collected from a number of documents from the NASREQ, ROAMOPS, MOBILEIP, and AAA work- ing groups. The intention is to present a detailed-level list of the summarized requirements in [1] as well as including some important requirements from [2,3, and 4]. Arkko Informational [Page 1] INTERNET-DRAFT Accounting Requirements October 29, 1999 4.1. 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 [6]. 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 docu- ments will specify whether these features are required, recommended, or optional. For example, requiring that a protocol support confidential- ity 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." 5. Requirements Requirements are listed in five categories: - General - Accounted Events - Data Formats - Data Contents - Security Arkko Informational [Page 2] INTERNET-DRAFT Accounting Requirements October 29, 1999 5.1.
