IP Over Asynchronous Transfer Mode (ipatm) Charter Status: Concluded May, 1996 Chair(s): Mark Laubach 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. Request for Comments:
