Abstract
This document summarises Internet Engineering Task Force (IETF) and
International Telecommunication Union (ITU-T) documents related to
Accounting. A classification scheme for the Accounting Attributes in
the summarised documents is presented. Exchange formats for
Accounting data records are discussed, as are advantages and
disadvantages of integrated versus separate record formats and
transport protocols. This document discusses service definition
independence, extensibility, and versioning. Compound service
definition capabilities are described.
