Technical Summary
 
This document describes a bandwidth saving method for exporting
flow or packet information using the IP Flow Information Export
(IPFIX) protocol.  As the PSAMP protocol is based on IPFIX, these
considerations are valid for PSAMP exports as well.
This method works by separating information common to several flow
records from information specific to an individual flow record.
 
Working Group Summary
 
The WG discussed various ways to reduce redundancy in IPFIX records,
and has reached consensus on this document.  This document does not
require any changes to the IPFIX Protocol or Information Model. 

Protocol Quality
 
This document has been reviewed by by the IPFIX and PSAMP Working 
Group Chairs. Although it is an informational document the WG chairs
required for an IETF Last Call to be conducted, in order to make sure that
the content of the document refelcts the IETF community consensus. The
document was reviewed for the IESG by Dan Romascanu.
