Re: WG last call on Sampling and Filtering Techniques for IP Packet Selection

BTW, this concern is also valid for draft-ietf-psamp-framework-09.txt

Regards, Benoit.
Tanja,

I read the draft (sorry, couldn't read earlier), and I have one issue left.

In this draft, one of your change is:
-    Low level filter definition substituted by simple filter definition based on IPFIX flow attributes
       - No masks and ranges (exept source and dest addresses)
       - No OR operation, AND realized by concatenating filters
This change is welcome.
However, I think it should be propagated to the "Router State Filtering", which still allows OR and NOT
 6.3 Router State Filtering 
     
    This class of filters select a packet on the basis of router 
    state conditions. The following list gives examples for such 
    conditions. Conditions can be  combined with AND, OR or NOT 
    operators. 
  
       - Ingress interface at which the packet arrives equals a 
          specified value 
       - Egress interface to which the packet is routed equals a 
          specified value 
       - Packet violated Access Control List (ACL) on the router 
       - Reverse Path Forwarding (RPF) failed for the packet 
       - Resource Reservation is insufficient for the packet 
       - No route found for the packet 
       - Origin BGP AS [RFC1771] equals a specified value or lies 
          within a given  range  
       - Destination BGP AS equals a specified value or lies within 
          a given range
Regards, Benoit.


Hi all,

for reviewing the packet selection draft,  please use the document published under:

http://www.ietf.org/internet-drafts/draft-ietf-psamp-sample-tech-05.txt


(Please do not use the document that I did send on the list, because I had to make a few modifications to the IPR and Copyright section to be conformant to the new IETF format. Therefore the published draft slightly differs from the document that I did send before.)

Thanks,
Tanja

Dear all,

After long discussions, our document on

Sampling and Filtering Techniques for IP Packet Selection
draft-ietf-psamp-sample-tech-05.txt

is ready for WG last call.

The call will last two weeks and close on Friday, November 5th
just two days before IETF#61.  Then we can discuss raised issues
at our session and (hopefully) solve them quickly.

Please read the document and send your comments!

Thanks,

   Juergen
