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.
