   Abstract

   The discussions of the IP over ATM working group over the last
   several years have produced a diverse set of proposals, some of which
   are no longer under active consideration.  A categorization is
   provided for the purpose of focusing discussion on the various
   proposals for IP over ATM deemed of primary interest by the IP over
   ATM working group.  The intent of this framework is to help clarify
   the differences between proposals and identify common features in
   order to promote convergence to a smaller and more mutually
   compatible set of standards.  In summary, it is hoped that this
   document, in classifying ATM approaches and issues will help to focus
   the IP over ATM working group's direction.

1.  Introduction

   The IP over ATM Working Group of the Internet Engineering Task Force
   (IETF) is chartered to develop standards for routing and forwarding
   IP packets over ATM sub-networks.  This document provides a
   classification/taxonomy of IP over ATM options and issues and then
   describes various proposals in these terms.

   The remainder of this memorandum is organized as follows:

   o Section 2 defines several terms relating to networking and
     internetworking.

   o Section 3 discusses the parameters for a taxonomy of the
     different ATM models under discussion.

   o Section 4 discusses the options for low level encapsulation.
