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.
