Specification of the IP Flow Information eXport (IPFIX) Protocol
for the Exchange of Flow Information
draft-ietf-ipfix-protocol-rfc5101bis-02
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 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.
