Products like SolarWinds NetFlow Traffic Analyzer or Paessler PRTG provide "all-in-one" ease of use with professional support and extensive integration libraries.
A 10Gbps link can generate 3,000 to 5,000 flows per second (fps). A 100Gbps backbone generates significantly more.
At its core, NetFlow is a network protocol developed by Cisco Systems, but the term has since become a generic label for flow monitoring technologies (including sFlow, IPFIX, and J-Flow). Unlike deep packet inspection (DPI), which looks inside the content of every message (raising privacy and processing concerns), NetFlow is a metadata-based approach. A NetFlow-enabled router or switch examines packets passing through an interface and groups them into "flows." A flow is defined as a unidirectional sequence of packets that share the same key characteristics: source/destination IP addresses, source/destination ports, protocol type, and Type of Service (ToS).
