scope:

The Fibre Channel Backbone - 3 (FC-BB-3) standard consists of four distinct Fibre Channel mappings resulting in the following four models: - FC-BB-3_ATM (FC over ATM backbone network) - FC-BB-3_SONET (FC over SONET backbone network) - FC-BB-3_IP (FC over TCP/IP backbone network) - FC-BB-3_GFPT (FC over SONET/SDH/OTN/PDH backbone network using GFPT adaptation) Figure 1, figure 2, and figure 3 illustrate the scope and the major components of the FC-BB-3 models and its relationship to the FCIP standard and the ATM Forum/ITU-T standards. Table 1 shows the organization of this standard. FC-BB-3_IP, FC-BB-3_ATM, FC-BB-3_SONET, and FC-BB-3_GFPT do not interoperate in any way and are independent models.
