   Specification of the IP Flow Information eXport (IPFIX) Protocol 
                  for the Exchange of Flow Information
                draft-ietf-ipfix-protocol-rfc5101bis-08
                                    

Abstract 

   This document specifies the IP Flow Information Export (IPFIX)
   protocol that serves for transmitting Traffic Flow information over
   the network. In order to transmit Traffic Flow information from an
   Exporting Process to a 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.
