                          IPv4 over IEEE 1394

Status of this Memo

   This document specifies an Internet standards track protocol for the
   Internet community, and requests discussion and suggestions for
   improvements.  Please refer to the current edition of the "Internet
   Official Protocol Standards" (STD 1) for the standardization state
   and status of this protocol.  Distribution of this memo is unlimited.

ABSTRACT

   This document specifies how to use IEEE Std 1394-1995, Standard for a
   High Performance Serial Bus (and its supplements), for the transport
   of Internet Protocol Version 4 (IPv4) datagrams; it defines the
   necessary methods, data structures and codes for that purpose. These
   include not only packet formats and encapsulation methods for
   datagrams, but also an address resolution protocol (1394 ARP) and a
   multicast channel allocation protocol (MCAP). Both 1394 ARP and MCAP
   are specific to Serial Bus; the latter permits management of Serial
   Bus resources when used by IP multicast groups.

1. INTRODUCTION

   This document specifies how to use IEEE Std 1394-1995, Standard for a
   High Performance Serial Bus (and its supplements), for the transport
   of Internet Protocol Version 4 (IPv4) datagrams. It defines the
   necessary methods, data structures and codes for that purpose and
   additionally defines methods for an address resolution protocol (1394
   ARP) and a multicast channel allocation protocol (MCAP)---both of
   which are specific to Serial Bus.

   The group of IEEE standards and supplements, draft or approved,
   related to IEEE Std 1394-1995 is hereafter referred to either as 1394
   or as Serial Bus.

   1394 is an interconnect (bus) that conforms to the CSR architecture,
   ISO/IEC 13213:1994. Serial Bus permits communications between nodes
