Abstract

   This document defines the Common Reliable Accounting for Network
   Element (CRANE) protocol that enables efficient and reliable delivery
   of any data, mainly accounting data from Network Elements to any
   systems, such as mediation systems and Business Support Systems
   (BSS)/ Operations Support Systems (OSS).  The protocol is developed
   to address the critical needs for exporting high volume of accounting
   data from NE's with efficient use of network, storage, and processing
   resources.

   This document specifies the architecture of the protocol and the
   message format, which MUST be supported by all CRANE protocol
   implementations.
