RFC 3146          IPv6 Packets over IEEE 1394 Networks      October 2001


   unicast_FIFO    This field MUST specify the 48-bit offset of the
                   node's FIFO available for the receipt of IPv6
                   datagrams.  The offset of a node's unicast FIFO
                   MUST NOT change, except as the result of a power
                   reset.

   reserved        This field MUST be set to all zeros by the sender
                   and ignored by the receiver.

   Note that node_ID may change when 1394 bus-reset occurs.  The mapping
   cache held in the node SHOULD be cleared on 1394 bus-reset.

   According to [1394], the maximum data payload and the transmission
   speed SHOULD be determined based on the sender's capability, the
   recipient's capability, and the PHYs of all intervening nodes.

9. IPv6 MULTICAST

   By default, all best-effort IPv6 multicast MUST use asynchronous
   stream packets whose channel number is equal to the channel field
   from the BROADCAST_CHANNEL register.  In particular, datagrams
   addressed to all-nodes multicast addresses, all-routers multicast
   addresses, and solicited-node multicast addresses [AARCH] MUST use
   the default channel specified by the BROADCAST_CHANNEL register.

   Best-effort IPv6 multicast for other multicast group addresses may
   utilize a different channel number if such a channel number is
   allocated and advertised prior to use, by the multicast channel
   allocation protocol (MCAP), as described in [IP1394].

   When a node wishes to receive multicast data addressed to other than
   all-nodes multicast addresses, all-routers multicast addresses, and
   solicited-node multicast addresses, it MUST confirm if the channel
   mapping between a multicast group address and a channel number exists
   using MCAP, as described in "9.3 Multicast Receive" in [IP1394].

   The implementation of MCAP is optional for send-only nodes.  A node
   MAY transmit multicast data addressed to any multicast addresses into
   the default broadcast channel regardless of the existing allocation
   of the channel.  If a node wishes to transmit multicast data on other
   than the default channel, it MUST first confirm by MCAP whether or
   not a channel number for the group address has been already
   allocated.  The implementors are encouraged to use this protocol when
   transmitting high-rate multicast streams.

   The MCAP 'type' value for IPv6 group address descriptor is 2.

10. IANA CONSIDERATIONS

   IANA has assigned a value of 0x000002 for "Unit_SW_Version for IPv6
   over IEEE1394" out of the "CSR Protocol Identifiers" name space, as
   described in section 5.  The details of the "CSR Protocol
   Identifiers" namespace is described in "10. IANA CONSIDERATIONS" of
   [IP1394].

   Section 9.1 of [IP1394] defines MCAP group address descriptors, which
   include an 8-bit type name space.  This document requests that IANA
   maintain a name space to manage MCAP group address descriptors.  The
   initial assignments for that table are:

       Value        Usage
       0            reserved
       1            IPv4 Multicast Address
       2            IPv6 Multicast Address
       255          reserved

   Additional values from the range 3-254 can be assigned through
   Standards Action [RFC 2434].

11. Security Considerations

   IPv6 over IEEE1394 does not introduce any additional security
   considerations over [IP1394].  The security concerns described in
   "11. SECURITY CONSIDERATIONS" in [IP1394] apply here as well.

12. Acknowledgment

   The authors would like to acknowledge the authors of [IP1394] and
   [ETHER] since some part of this document has been derived from them.
