            Information Model for IP Flow Information Export

Status of This Memo

   This document specifies an Internet standards track protocol for the
   Internet community, and requests discussion and suggestions for
   improvements.  Please refer to the current edition of the "Internet
   Official Protocol Standards" (STD 1) for the standardization state
   and status of this protocol.  Distribution of this memo is unlimited.

Abstract

   This memo defines an information model for the IP Flow Information
   eXport (IPFIX) protocol.  It is used by the IPFIX protocol for
   encoding measured traffic information and information related to the
   traffic Observation Point, the traffic Metering Process, and the
   Exporting Process.  Although developed for the IPFIX protocol, the
   model is defined in an open way that easily allows using it in other
   protocols, interfaces, and applications.
