Technical Summary
 
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
Measurement Processes and for reporting the technique in use to a
Collector.
 
Working Group Summary
 
This document has been a regular WG document. There is strong consensus in
the working group concerning the content of this document and the fact
that it describes an appropriate sampling and filtering techniques for IP
packet selection.
 
Protocol Quality
 
Dan Romascanu reviewed this document for the IESG, Vijay K. Gurbani did
the Gen-Art review and Mark Allman performed an expert review on behalf of
the TSV directorate. There are no known implementations yet, but two
vendors and academic research institutes announced implementations. The
document is fully supported by the WG and there has no concerns been
raised that there are better alternatives or that the document is not
useful.

     classification for flow analysis. All these factors can lead to
     an overwhelming amount of measurement data, resulting in high
     demands on resources for measurement, storage, transport and
     post processing.

6)  In Section 6.1
OLD
     Property match operations should be available for different
     protocol portions of the packet header:
      
           (i) the IP header (excluding options in IPv4, stacked
                headers in IPv6)
           
          (ii) transport header
