ATM + ROLC = ION (new working group)

["Andrew G. Malis" <[e-mail]>]

[Please send all replies to this message ONLY to [e-mail].]

As you can see from the announcement below, the IP/ATM and ROLC
working groups are merging.

George Swallow of Cisco and I are the co-chairs for the combined
group, which is called Internetworking Over NBMA (ion), and is jointly
in the Internet and Routing areas.  Our intention for the merge is to
carry forward the existing work while preventing duplication of effort
between the two groups.  I've attached the working group charter to
this message; the charter should clarify any questions you may have.

I've created a new working group mailing list, [e-mail], which at
the moment simply contains indirect pointers to the existing ip-atm
and rolc mailing lists.  To join this list, simply send a message
containing the word "subscribe" in the message body to
[e-mail] (we use majordomo for list management).

I would ask that those of you sending email to the existing ip-atm and
rolc lists please move your discussions to [e-mail]; it will
reach at the very least the people that have already been reading the
mail.  However, to prevent unnecessary mail duplication, I would ask
that at your convenience, those of you on the old lists please send
the following message body to [e-mail]:

subscribe ion
unsubscribe ip-atm
unsubscribe rolc

(if you were on only one of the lists, it will ignore the extra
unsubscribe line).

The old ip-atm and rolc lists will eventually be retired (warnings
will be sent beforehand).  Frankly, I am starting a new list rather
than directly merging the two old lists because of the large number of
obsolete addresses on the existing lists.

Please send replies to this message and comments on the charter to
the ion list only, please.

The working group has an FTP archive at ftp://ftp.nexen.com/pub/ion/,
and the Cell Relay Retreat at Indiana University has generously agreed
to provide a hypermail archive for the list's email, at
http://netlab.ucs.indiana.edu/hypermail/ion/ (thanks, Allen and
Chris!).

We won't rename any existing internet drafts, but as new versions come
out, we'll replace the "ipatm" or "rolc" in their names with "ion".

I have reserved four meeting slots in Montreal, to replace the usual
two each for ip-atm and rolc; however, I suspect we may not need all
four, depending on the agenda.  The slots are:

MONDAY, June 24, 1996
1300-1500  Afternoon Sessions I
1530-1730  Afternoon Sessions II
 
TUESDAY, June 25, 1996
1300-1500  Afternoon Sessions I
1530-1730  Afternoon Sessions II

Please send email to George and me if you have an internet draft you
will be bringing into the meeting and/or want time on the agenda.  The
secretariat would appreciate it if we could put together the agenda as
quickly as possible, so that any extra sessions can be returned to
them for other groups' use.  We're scheduled to be on the mbone, so
please in mind that presentations must be prepared in advance (and not
handwritten) so that they can be included in the mbone broadcast.
Having them available in advance will also allow me to put them up for
FTP for the convenience of people that can't make the meeting.

The charter is attached below.

Cheers,
Andy (and George)

Subject: WG ACTION: Internetworking Over NBMA (ion)


A new working group has been formed, jointly chartered in the
Internet and Routing Area of the IETF. For more information,

Description of Working Group:
 
Note: This Working Group is jointly chartered by the Routing Area.

Motivation

The Internetworking Over NBMA Working Group was formed to combine the
work of two previous working groups, IP Over ATM (ipatm) and Routing
Over Large Clouds (rolc), because these two groups were often working
very closely together on similar, if not identical, problems and
solutions.  The group will be evolutionary, not revolutionary; it will
continue the work in the previous groups on the NBMA Next Hop
Resolution Protocol (NHRP), IPv4 over ATM, and IPv6 over ATM.

Description

This WG will focus on the issues involved in internetworking network
layer protocols over NBMA (non-broadcast multiple access) subnetwork
technologies, such as ATM, Frame Relay, SMDS, and X.25 private and
public networks.  The group will endeavor to make all its solutions
applicable to the entire range of network layer protocols and NBMA
subnetworks.  We recognize, however, that there will be cases where
specific optimizations to IPv4, IPv6, and particular subnetwork
technologies will result in better service to the user.
 
The group will focus on protocols for encapsulation, multicasting,
addressing, address resolution and neighbor discovery, interactions
with and optimization of internetworking-layer routing protocols when
run over NBMA subnetworks, and protocol-specific network management
support, as appropriate.  The working group will submit these
protocols for standardization.
 
The working group may also produce experimental and informational
documents, including "Best Current Practices" guidelines, as
required.
 
For ATM, the WG will continue the ipatm WG's transition from the LIS
model described in RFC 1577 to the generalized NHRP model developed by
the rolc WG, including a transition plan for existing networks.
 
The working group will coordinate its activities with the following
other working groups:
 
1) Integrated Services over Specific Lower Layers (issll), for
   coordinating Quality of Service (QoS) issues and the implementation
   of IP integrated services capabilities (RSVP, the service models,
   etc.) over NBMA networks.
 
2) IP Next Generation (ipng), for IPv6 over ATM coordination.

The working group will also coordinate its work with other relevant
standards bodies (e.g., ATM Forum, Frame Relay Forum, ANSI T1S1,
ITU-T) and make recommendations to these organizations regarding the
requirements for IP internetworking where the current published
subnetwork standards, practices, or functionality do not meet the
needs of internetworking.
 
The working group will not develop subnetwork layer standards.
 
 Goals and Milestones: 
 
     Done Publish the IP over ATM Framework document (now RFC 1932), submit the
          MARS draft to IESG as a Proposed Standard.                           

   May 96 Begin work on internetworking over Frame Relay SVCs (RFC 1490 
          extension), using NHRP for address resolution.                       

   Jun 96 Revise drafts on NHRP, 1577 revisions, server synchronization 
          (applicable to both NHRP and ATMARP), multicast server and broadcast 
          for ATM, IPv6 neighbor discovery, ATM UNI 4.0 signaling (RFC 1755 
          update), Classical IP and NHRP MIBs, NHRP applicability, ATMARP to 
          NHRP transition plan, and router-router NHRP.                        

   Sep 96 IAB and IESG review of WG Status, and plans. This meeting will be 
          scheduled to occur during SIGCOMM '96.                               

   Dec 96 Submit NHRP, RFC 1577 revisions, and server synchronization to the 
          IESG as a Proposed Standard, complete the ATMARP to NHRP transition 
          plan and NHRP applicability statement, revise drafts on multicast 
          server and broadcast for ATM, IPv6 neighbor discovery, classical IP 
          and NHRP MIBs, router-router NHRP, ATM UNI 4.0 signaling (RFC 1755 
          upd                                                                  

   Mar 97 Submit IPv6 neighbor discovery, classical IP and NHRP MIBs, 
          router-router NHRP, ATM UNI 4.0 signaling (RFC 1755 update), 
          multicast server and broadcast for ATM, and NHRP for Frame Relay SVCs
          to the IESG.
