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.
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.
This memo draws heavily in both concept and text from , written by Jon Postel and Joyce K. Reynolds of ISI and , 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.
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.
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 , , and in . 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 Service exhibits high throughput and low delay, and provides the transparent transport and delivery of up to 9188 octets of user information in a single transmission.
o No explicit flow control mechanisms are provided;...
