Re: Intellectual Property 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.
http://www.ietf.org/ietf/IPR/cisco-claise-netflow.txt

Thanks for shedding some light.

Regards, Benoit.
