Fibre Channel provides a general data transport vehicle for Upper Level Protocols (ULPs) such as Intelligent Peripheral Interface (IPI) and Small Computer System Interface (SCSI) command sets, the High-Performance Parallel Interface (HIPPI) data framing, IP (Internet Protocol), ANSI/IEEE 802.2, and others. This part of ISO/IEC 14165 defines the frame format and protocol definitions required to transfer information for upper-layer protocols that use the High-Performance Parallel Interface Framing Protocol (HIPPI-FP) when using a lower-layer serial link interface operating according to the Fibre Channel Physical and Signaling Interface (FC-PH) and Fibre Channel Enhanced Physical (FC-EP) requirements. For example, the HIPPI upper-layer protocols would use FC-FP when the underlying physical layer is Fibre Channel, and would use HIPPI-FP when the underlying physical layer is HIPPI.
