IPFC

IPFC stands for Internet Protocol over Fibre Channel. It governs a set of standards created in January 2006 for address resolution (ARP) and transmitting IPv4 and IPv6 network packets over a Fibre Channel (FC) network.[1] IPFC makes up part of the FC-4 protocol-mapping layer of a Fibre Channel system.[2]

In IPFC, each IP datagram packet is wrapped into a FC frame, with its own header, and transmitted as a sequence of one or more frames. The receiver at the other end received the frames, strips the FC headers and reassembles the IP packet.[3] IP datagrams of up to 65,280 bytes in size may be accommodated.[4] ARP packet transmission works in the same fashion.[1] Each IP datagram exchange is unidirectional, although IP and TCP allow for bidirectional communication within their protocols.[4]

IPFC is an application protocol that is typically implemented as a device driver in an operating system.[5] IP over FC plays a less important role in storage area networking than SCSI over Fibre Channel or IP over Ethernet.[5][6] IPFC has been used, for example, to provide clock synchronization via the Network Time Protocol (NTP).[7]
