I'd like to point out that the a key mechanism for doing classification
(in the IPFIX metering process)
is filtering. Now, filtering is one of the main aspects of the
selecting process in PSAMP. In fact,
one could configure the filtering process in PSAMP so that the packet
stream records resulting from
the measurement will be flow records.
With this viewpoint, it could be said that PSAMP could subsume IPFIX,..yes?
The other point I'd like to make is that a desireable feature for the
selected IPFIX
protocol to have will be a way to configure the exporting process.
This will be
great for PSAMP, and elliminates the need to maintain another protocol
or method
just for the configuration purposes.
Regards,
Alex.

A New Internet-Draft is available from the on-line Internet-Drafts directories. Title : On the Relationship between PSAMP and IPFIX Author(s) : J. Quittek, B. Claise Filename : draft-quittek-psamp-ipfix-01.txt Pages : 14 Date : 2003-3-4 This memo discusses the relationship between the packet sampling (PSAMP) Working Group and the IP flow information export (IPFIX) Working Group. The goals of writing this memo are: avoiding duplication of work, increase mutual benefits between the groups, and harmonize the documents and standards developed by the groups. Therefore, potential overlap of both group's activities is analyzed, activities in both groups that potentially complement each other are pointed out, and common issues are listed that should be harmonized between the groups.

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.
