RFC 5475 Techniques for IP Packet Selection March 2009
Abstract
This document describes Sampling and Filtering techniques for IP
packet selection. It provides a categorization of schemes and
defines what parameters are needed to describe the most common
selection schemes. Furthermore, it shows how techniques can be
combined to build more elaborate packet Selectors. The document
provides the basis for the definition of information models for
configuring selection techniques in Metering Processes and for
reporting the technique in use to a Collector.
