ISO/IEC 14165-251 (2008-01)

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, FC-FS, describes the framing and signalling interface of a high-performance serial link for support of Fibre Channel 4s associated with upper level protocols (e.g., SCSI, IP, SBCCS, VI). It includes additional link services in support of new functions defined by the Fibre Channel family of documents and improvements and clarifications to the definitions of existing services as dictated by experience with existing implementations. This standard also defines and includes other capabilities designed to improve the performance of existing Fibre Channel products and fit those products for new applications.
