Foreword
ISO (the International Organization for Standardization) and IEC (the International
Electrotechnical Commission) form the specialized system for worldwide
standardization. National bodies that are members of ISO or IEC participate in the
development of International Standards through technical committees established by
the respective organization to deal with particular fields of technical activity. ISO and
IEC technical committees collaborate in fields of mutual interest. Other international
organizations, governmental and non-governmental, in liaison with ISO and IEC, also
take part in the work.
In the field of information technology, ISO and IEC have established a joint technical
committee, ISO/IEC JTC 1. Draft International Standards adopted by the joint technical
committee are circulated to national bodies for voting. Publication as an International
Standard requires approval by at least 75% of the national bodies casting a vote.
International Standard ISO/IEC 14165-211 was prepared by Joint Technical Committee
ISO/IEC JTC 1, Information Technology, Subcommittee SC 25, Interconnection of
Information Technology Equipment.
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.
In this document the term Fibre Channel refers to the FC-PH and FC-EP entities only.
In relation to the Fibre Channel structures defined in FC-PH, this document, FC-FP,
represents an FC-4.
Characteristics of FC-FP include:
– Encapsulation of HIPPI-FP packets, including the HIPPI-FP header, in Fibre
Channel Information Units and Exchanges;
– Separation of the HIPPI-FP D1_Data_Set and D2_Data_Set.
ISO/IEC 14165 will consist of the following parts, under the general title Information
technology – Fibre Channel:
– Part 111: Physical and Signaling Interface (FC-PH)
– Part 112: 2nd Generation Physical Interface (FC-PH-2)
– Part 113: 3rd Generation Physical Interface (FC-PH-3)
– Part 121: Arbitrated Loop (FC-AL)
– Part 131: Switched Fabric and Switch Control Requirements (FC-SW)
