scope:

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 mappings for transporting Fibre Channel frames across the following types of backbone networks: ATM, SONET, and TCP/IP. The backbone mappings support the attachment of Fibre Channel switches using the facilities of the underlying backbone network. Details regarding the mappings of Fibre Channel to ATM and SONET are completely specified in this FC-BB-2 standard. With respect to TCP/IP, the FC-BB-2 and IETF Fibre Channel over TCP/IP specifications together describe how Fibre Channel frames are transported over a TCP/IP backbone.
