A New Internet-Draft is available from the on-line Internet-Drafts directories.
Title : Guidelines for IPFIX Implementations on Middleboxes
Author(s) : J. Quittek
Filename : draft-quittek-ipfix-middlebox-00.txt
Pages : 11
Date : 2004-2-6
This memo gives recommendations for the implementation of IP Flow
Information eXport (IPFIX) metering processes and IPFIX exporting
processes on middleboxes, such as firewalls, network address
translators, tunnel endpoints, packet classifiers, etc. Middlebox
functions potentially change properties of traffic flows passing the
box, for example NATs change addresses in header fields and firewalls
change the numbers of packets and bytes belonging to a traffic flow.
An IPFIX implementation on a middlebox should reflect this by the way
it selects and reports the observation point and by the way it
measures and reports traffic flows.

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
