This document describes anonymisation techniques for IP flow data and the export of anonymised data using the IPFIX protocol. It provides a categorization of common anonymisation schemes and defines the parameters needed to describe them. It provides guidelines for the implementation of anonymised data export and storage over IPFIX, and describes an Options-based method for anonymization metadata export within the IPFIX protocol, providing the basis for the definition of information models for configuring anonymisation techniques within an IPFIX Metering or Exporting Process, and for reporting the technique in use to an IPFIX Collecting Process.
