   Specification of the IP Flow Information eXport (IPFIX) Protocol 
            for the Exchange of IP Traffic Flow Information
                draft-ietf-ipfix-protocol-rfc5101bis-00 
                                    

Abstract 

   This document specifies the IP Flow Information Export (IPFIX)
   protocol that serves for transmitting IP Traffic Flow information
   over the network.  In order to transmit IP Traffic Flow information
   from an Exporting Process to an information Collecting Process, a
   common representation of flow data and a standard means of
   communicating them is required.  This document describes how the
   IPFIX Data and Template Records are carried over a number of
   transport protocols from an IPFIX Exporting Process to an IPFIX
   Collecting Process.  This document obsoletes RFC 5101.
