Specification of the IP Flow Information Export (IPFIX) Protocol
for the Exchange of Flow Information
Abstract
This document specifies the IP Flow Information Export (IPFIX)
protocol, which serves as a means 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 are 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.
