What is IP Flow Information Export, the IETF open standard version of NetFlow for flow-based traffic monitoring?

• A. NetFlow
• B. IPFIX
• C. sFlow
• D. Bandwidth

Answer: (B)

IP Flow Information Export is the IETF open standard for exporting flow-based network measurement data. It defines how to format, transport, and interpret flow records from routers and switches to a collector, using a template-based approach so different vendors can interoperate. IPFIX originated from NetFlow and was standardized by the IETF to provide a universal, interoperable method for flow data. NetFlow is Cisco’s original implementation, while IPFIX generalizes and standardizes that approach. sFlow uses a different architecture with packet sampling, not the IPFIX export mechanism, and bandwidth is just a measurement, not a protocol for exporting flow data. So the IETF open standard version is IPFIX.
