What is IPFIX?

IPFIX (Internet Protocol Flow Information Export) is an IETF standard protocol for exporting network flow information. It's used to collect and report information about network traffic, such as source and destination IP addresses, ports, protocols, packet and byte counts, timestamps, and other flow characteristics. IPFIX is commonly used for network monitoring, security analysis, traffic engineering, and billing purposes. It provides a standardized way for network devices like routers and switches to export flow data to collectors for analysis and reporting.
