[IPFIX] I-D ACTION:draft-ietf-ipfix-flow-selection-tech-03.txt

A New Internet-Draft is available from the on-line Internet-Drafts 
This draft is a work item of the IP Flow Information Export Working Group of the IETF.

	Title		: Flow Selection Techniques

Flow selection is the process of selecting a subset of flows from all
   flows observed at an observation point.  The objective of flow
   selection is to reduce the effort of post-processing flow data and
   transferring flow records.  The flow selection process can be enabled
   at different stages of the measurement process.  It can be applied
   either directly after classification or at recording/exporting time
   by limiting the number of flows to be stored and/or exported to the
   collecting process.  This document describes motivations for flow
   selection and presents flow selection techniques.  It furthermore
   provides an information model for configuring flow selection
   techniques and discusses what information about a flow selection
   process is worth exporting through a suitable information model.

[IPFIX] secdir review of draft-ietf-ipfix-mediators-framework-09.txt

I have reviewed this document as part of the security directorate's  
ongoing effort to review all IETF documents being processed by the  
IESG. These comments were written primarily for the benefit of the  
security area directors. Document editors and WG chairs should treat  
these comments just like any other last call comments.

This document adds a new concept to the IPFIX architecture (RFC 5470):
IPFIX Mediation. This concept allows conversion, correlation, selection,
and other transformations on IPFIX records.

The document is clear and the Security Considerations section
seems to adequately cover the issues raised. I don't see any
problems from a security perspective.
