Abstract

   The field of Accounting Management is concerned with the collection
   of resource consumption data for the purposes of capacity and trend
   analysis, cost allocation, auditing, and billing.  This document
   describes each of these problems, and discusses the issues involved
   in design of modern accounting systems.

   Since accounting applications do not have uniform security and
   reliability requirements, it is not possible to devise a single
   accounting protocol and set of security services that will meet all
   needs.  Thus the goal of accounting management is to provide a set of
   tools that can be used to meet the requirements of each application.
   This document describes the currently available tools as well as the
   state of the art in accounting protocol design.  A companion
   document, RFC 2924, reviews the state of the art in accounting
   attributes and record formats.
