                          SNMP over AppleTalk

Status of this Memo

   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.

Introduction

   This memo describes the method by which the Simple Network Management
   Protocol (SNMP) as specified in [1] can be used over AppleTalk
   protocols [2] instead of the Internet UDP/IP protocol stack.  This
   specification is useful for network elements which have AppleTalk
   support but lack TCP/IP support.  It should be noted that if  a
   network element supports multiple protocol stacks, and UDP is
   available, it is the preferred network layer to use.

   SNMP has been successful in managing Internet capable network
   elements which support the protocol stack at least through UDP, the
   connectionless Internet transport layer protocol.  As originally
   designed, SNMP is capable of running over any reasonable transport
   mechanism (not necessarily a transport protocol) that supports bi-
   directional flow and addressability.

   Many non-Internet capable network elements are present in networks.
   Some of these elements are equipped with the AppleTalk protocols.
   One method of using SNMP to manage these elements is to define a
   method of transmitting an SNMP message inside an AppleTalk protocol
   data unit.

   This RFC is the product of the SNMP over a Multi-protocol Internet
   Working Group of the Internet Engineering Task Force (IETF).

1. Background

   The AppleTalk equivalent of UDP (and IP) is DDP (Datagram Delivery
   Protocol).  The header field of a DDP datagram includes (at least
   conceptually) source and destination network numbers, source and
