Excerpt
Introduction: There are several applications that require flow-based IP traffic measurements. Such measurements could be performed by a router while forwarding the traffic, by a middlebox [RFC3234], or by a traffic measurement probe attached to a line or a monitored port. This memo defines requirements for exporting traffic flow information out of these boxes for further processing by applications located on other devices. They serve as input to the standardization of the IPFIX protocol specifications.
