1.      Introduction

   This document describes a flow controlled, atomic multicasting
   transport protocol (MTP).  The purpose of this document is to present
   sufficient information to implement the protocol.

   The MTP design has been influenced by the large body of the
   networking and distributed systems literature and technology that has
   been introduced during the last decade and a half.  Representative
   sources include [Xer81], [BSTM79] and [Pos81] for transport design,
   and [Bog83] and [DIX82] for general concepts of broadcast and
   multicast.  [CLZ87] influenced MTP's retransmission mechanisms, and
   [Fre84] influenced the transport timings. MTP over IP uses mechanisms
