Flow Selection Techniques
Abstract
The Intermediate Flow Selection Process is the process of selecting a
subset of Flows from all observed Flows. The Intermediate Flow
Selection Process may be located at an IP Flow Information Export
(IPFIX) Exporter or Collector, or within an IPFIX Mediator. It
reduces the effort of post-processing Flow data and transferring Flow
Records. This document describes motivations for using the
Intermediate Flow Selection process and presents Intermediate Flow
Selection techniques. It provides an information model for
configuring Intermediate Flow Selection Process techniques and
discusses what information about an Intermediate Flow Selection
Process should be exported.
