This standard consists of distinct Fibre Channel mappings resulting in the following models: FC-BBIP (FC over TCP/IP backbone network); Transparent FC-BB consisting of: FC-BBGFPT (FC over SONET/SDH/OTN/PDH backbone network using GFPT adaptation); FC-BBPW (FC over MPLS network using PW adaptation), and FC-BBE (FC over Ethernet).
