Description of Working Group:

NOTE: This WG joined with the ROLC WG to form the ION Working Group

The IP Over Asynchronous Transfer Mode Working Group will focus on the
issues involved in internetworking the IPv4 and IPv6 protocols over
Asynchronous Transfer Mode (ATM) networks.  The goal for the working
group is to produce standards for the TCP/IP Internet protocol suite.

The working group will develop models of IP over ATM internetworking
architectures; e.g. the classical Logical IP Subnet (LIS) over ATM.
The working group will develop protocols for encapsulation,
multicasting, addressing, address resolution, neighbor discovery, use
of published ATM Forum UNI signaling for IP call set up and connection
negotiation, and network management, as appropriate, to allow the
operation of internetwork protocols over an ATM network.  The working
group will submit these protocols for standardization.

The working group will coordinate its activities with the following
working groups:

1) Routing over Large Cloud (rolc), for next hop address resolution
   extensions to the classic LIS model,

2) Integrated Services Working Group (intserv) for coordinating the
   support of the enhanced Internet service model within an ATM LIS,

3) IP Next Generation Working Group (ipngwg) for IPv6 over ATM
   coordination, and

4) Resource Reservation Setup Protocol (rsvp) for coordinating the
   support IP signaling within an ATM LIS.

The working group will coordinate its work with other relevant
standards bodies (e.g., ATM Forum, ANSI T1S1) and make recommendations
to these organizations regarding the requirements for IP
internetworking where the current published ATM standards, practices,
or functionality do not meet the needs of internetworking.

The working group will not develop physical layer standards for ATM.


 Goals and Milestones:

   JUN 95       Post first Internet-Draft detailing Miulticast Systems 
                Overview for IP Multicast over ATM. 

   JUN 95       Post first Internet-Draft update for combined RFC1577/1626 
                (Classical IP and ARP over ATM update with Default IP MTU 
                for use over ATM AAL5). 

   JUL 95       Submit proposal to IESG to elevate RFC1483 to Draft 
                Standard. 

   JUL 95       Post update to the Framework document as an Internet-Draft. 

   AUG 95       Submit combined RFC1577/1626 Internet-Draft to IESG for 
                consideration as a Proposed Standard. 

   AUG 95       Submit IPMC Internet-Draft <draft-ietf-ipatm-ipmc-xx.txt) 
                to IESG for consideration as a Proposed Standard. 

   SEP 95       Submit Framework Internet-Draft to IESG for consideration 
                as an Informational RFC. 

   DEC 95       Post an update to RFC1755 for UNI 4.0 (ATM Signaling 
                Support for IP over ATM) as an Internet-Draft.
