RE: Recharter IPoRPR WG

Folks,
 
Thanks for the comments on liaisons.
 
Since you may be unaware, I have been acting as an informal liaison between the IETF, IEEE 802.17 and ITU-T SG15 on the topic of RPR for the past year or more.
 
The original charter stated no formal liaisons, so I did not change it. However, I will discuss with our AD if making it formal would be appropriate.
 
That said, it is my view that there is currently no disconnect between any of these groups.  And that if there ever was, it would be my responsibility to resolve it.
 
Cheers,
Glenn.

I agree with Albert,  we should address the issues and order a process to facilitate between these standard bodies (i.e. liaisons ).  Once we develop this roadmap we can have a better understanding for the tasks at hand.

Glenn,

 

I know we're encouraging cross participation between the standards bodies but we really need a free and easy flow of information between IPORPR, IEEE 802.17 and ITU-T SG15 on established and developing specifications specially for those working towards RFCs within the IETF. I know we casually discussed this a while back but we don't have a mechanism nor an official notice from the other standards bodies as to how we are to facilitate this.

 

We have to address this before starting work on the drafts.

 

Thanks,

Albert

Italo,

Thanks for the review.

IP and MPLS encapsulation over RPR are in charter -- though I can see that is not completely clear from the latest version of the charter.

And the intent is coordination with all of ITU-T SG15 with Q9 being the coordination point as it has been in the past.

Cheers,
Glenn.

Glenn,

I think that the group should also cover the mapping of MPLS over RPR.

Moreover, regarding ITU SG15 relationships, I think we need to include also Q.11/15 and Q.12/15 in addition to Q.9/15 because all of these three questions are currently considering RPR.

Below you can find a proposed revised version of the "Description of Working Group".

Best regards, Italo

Description of Working Group:

Resilient Packet Rings (RPR), developed within the IEEE 802.17 RPR WG, provides substantial enhancements in both efficiency and flexibility over current bi-directional ring topologies. Benefits of resilient packet rings include spatial re-use (full utilization of both counter-rotating rings) while maintaining protection switching during media faults, as well as defined mechanisms for topology discovery, congestion control, and protection switching. Reference the IEEE 802.17 RPR WG at http://www.ieee802.org/17/ for further information.  IEEE 802.17-2004 is currently published and work is in progress on bridging enhancements.

The IPORPR Working Group will produce two documents:

   1) An IPORPR Framework that describes some of the features and
      characteristics of 802.17 RPR, and how they might be exploited
      by, e.g., IP or MPLS. For example, an RPR ring can be accessed
      in a number of ways: it can be viewed as a "dumb" LAN supporting
      traditional broadcast a la Ethernet (called "basic mode"), or its
      advanced features could be exploited.

   2) An IPORPR definition of how to transport IP and MPLS over 802.17 RPR in
      "basic mode". This document will cover encapsulation formats
      (e.g., IPv4/IPv6, MPLS), how to perform address resolution (e.g., ARP/ND), IP
      multicast transmission, priority mapping to the RPR
      "serviceClass", etc.

There are no formal liaisons between the IPORPR working group and other standards bodies.  However, cross participation is encouraged in the key RPR activities in these standards bodies:

- IEEE 802.17  (http://www.ieee802.org/17/)
- ITU-T SG15 Q9 (http://www.itu.int/ITU-T/studygroups/com15/sg15-q9.html)
- ITU-T SG15 Q11 (http://www.itu.int/ITU-T/studygroups/com15/sg15-q11.html)
- ITU-T SG15 Q12 (http://www.itu.int/ITU-T/studygroups/com15/sg15-q12.html)

Folks,
The IPoRPR WG has been in hibernation for quite some time.  Given the publication of IEEE 802.17 last year, it is time to shut down this WG...  or recharter and do something. Assuming there is some interest in the latter, I have attached a revised charter proposal that our AD will be reviewing with the IESG shortly. Let us know if you have any comments.
