Figure 2 depicts IPo1394 and its relationship to the other higher and lower-layer protocols mentioned in this document. <1>

Figure 2: Protocol stack showing IPo1394 and its relationship to other protocols

Sending and receiving IPv4 datagrams and 1394 Address Resolution Protocol (ARP) request and response packets over IPo1394 is specified in [RFC2734]. The Spanning Tree Algorithm and Protocol (STP) is used for network loop detection. Sending and receiving STP packets over IPo1394 is specified in this document. Sending and receiving Dynamic Host Configuration Protocol (DHCP) packets, as specified in [RFC2131], over IPo1394 is specified in [RFC2855].

IPo1394 uses a different link-layer addressing method than conventional 802.3/Ethernet. For more information, see [IEEE802.3]. This implies that the use of some fields in DHCP packets must be clarified to achieve interoperability between implementations of IPo1394 and DHCP. DHCP for IEEE 1394, as specified in [RFC2855], specifies the IPo1394 use of these fields of DHCP packets.<2>
