IP Flow Information Export
Internet Protocol Flow Information Export (IPFIX) is an IETF protocol, as well as the name of the working group defining the protocol. It was created based on the need for a common, universal standard of export for Internet Protocol flow information from routers, probes, and other devices that are used by mediation systems, accounting/billing systems, and network management systems to facilitate services such as measurement, accounting, and billing. The IPFIX standard defines how IP flow information is to be formatted and transferred from an exporter to a collector. Previously many data network operators were relying on the proprietary Cisco Systems NetFlow standard for traffic flow information export.
The IPFIX standards requirements were outlined in the original RFC 3917. Cisco NetFlow Version 9 was the basis for IPFIX. The basic specifications for IPFIX were published in 2008 as RFC 5101, RFC 5102 and RFC 5103.
