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
