         The Transmission of IP Datagrams over the SMDS Service

Status of this Memo

   This memo defines a protocol for the transmission of IP and ARP
   packets over a Switched Multi-megabit Data Service Network configured
   as a logical IP subnetwork.  This RFC specifies an IAB standards
   track protocol for the Internet community, and requests discussion
   and suggestions for improvements.  Please refer to the current
   edition of the "IAB Official Protocol Standards" for the
   standardization state and status of this protocol.  Distribution of
   this memo is unlimited.

Abstract

   This memo describes an initial use of IP and ARP in an SMDS service
   environment configured as a logical IP subnetwork, LIS (described
   below).  The encapsulation method used is described, as well as
   various service-specific issues.  This memo does not preclude
   subsequent treatment of the SMDS Service in configurations other than
   LIS; specifically, public or inter-company, inter-enterprise
   configurations may be treated differently and will be described in
   future documents.  This document considers only directly connected IP
   end-stations or routers; issues raised by MAC level bridging are
   beyond the scope of this paper.

Acknowledgment

   This memo draws heavily in both concept and text from [4], written by
   Jon Postel and Joyce K. Reynolds of ISI and [5], written by David
   Katz of Merit, Inc.  The authors would also like to acknowledge the
   contributions of the IP Over SMDS Service working group of the
   Internet Engineering Task Force.

Conventions

   The following language conventions are used in the items of
   specification in this document:

      o MUST, SHALL, or MANDATORY -- the item is an absolute
        requirement of the specification.
