Statement for the sampling techniques draft
Nick,
Benoit,
There is a more recent and specific IP statement from AT&T that will be
referred to in the next version of the framework draft:
http://www.ietf.org/ietf/IPR/att-ipr-draft-ietf-psamp-framework.txt
This is good, as this is more specific.
However, shouldn't you mention to which hashing/filtering/sampling technique(s)
your IPR refers.
Concerning other assertions of IP rights, I was referring to the
following psamp specific statement from Cisco, which will also be
referred to in the next version:
http://www.ietf.org/ietf/IPR/cisco-ipr-draft-ietf-psamp-protocol.txt
Very good.
Regards, Benoit.
Nick

Subject: Intellectual Property Statement for the sampling techniques
draft
Hi,
During his session, Nick Duffield mentioned that he wrote an IPR
section
in the sampling techniques draft, and that potentially we might need
one
for NetFlow.
I started to investigate and this leads me to this question.
The IPR statement is pretty vague, specifically if I follow the link
10.
Intellectual Property Statement
AT&T Corporation may own intellectual property applicable to
this
contribution. The IETF has been notified of AT&T's licensing
intent for the specification contained in this document. See
http://www.ietf.org/ietf/IPR/ATT-GENERAL.txt for AT&T's IPR
statement.
Should we specify exactly which method(s) AT&T has got a patent for?
And
what is the patent number?
For example, the NetFlow IPR is pretty unambiguous.

Thanks for shedding some light.
Regards, Benoit.
