Internet Protocol Flow Information Export (IPFIX) is an IETF protocol, as well as the name of the IETF 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 Cisco Systems' proprietary NetFlow technology 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 are documented in RFC 7011 through RFC 7015, and RFC 5103. == Architecture == The following figure shows a typical architecture of information flow in an IPFIX architecture: Metering, Exporter IPFIX Collector O--------------------------->O | | Observation Point v ---- IP Traffic ---> A Metering Process collects data packets at an Observation Point, optionally filters them and aggregates information about these packets. Using the IPFIX protocol, an Exporter then sends this information to a Collector. Exporters and Collectors are in a one-to-many relationship: One Exporter can send data to many Collectors and one Collector can receive data from many Exporters. 〔IEEE communications magazine,http://ieeexplore.ieee.org.lcproxy.shu.ac.uk/stamp/stamp.jsp?tp=&arnumber=5741152〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「IP Flow Information Export」の詳細全文を読む スポンサード リンク
