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.

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.

o SHOULD or RECOMMENDED -- the item should generally be followed

for all but exceptional circumstances.

o MAY or OPTIONAL -- the item is truly optional and may be

followed or ignored according to the needs of the implementor.

Introduction

The goal of this specification is to allow compatible and

interoperable implementations for transmitting IP datagrams and ARP

requests and replies.

The characteristics of the SMDS Service and the SMDS Interface

Protocol (SIP) are presented in [3], [6], and in [7]. Briefly, the

SMDS Service is a connectionless, public, packet-switched data

service. The operation and features of the SMDS Service are similar

to those found in high-speed data networks such as LANs:

o The SMDS Service provides a datagram packet transfer, where each

data unit is handled and switched separately without the prior

establishment of a network connection.

o The SMDS ...
