the capabilities of Fibre Channel over Ethernet networks:
* Encapsulation of native Fibre Channel frames into Ethernet Frames.
* Extensions to the Ethernet protocol itself to enable an Ethernet fabric in which frames are not routinely lost during periods of congestion.
* Mapping between Fibre Channel N_port IDs (aka FCIDs) and Ethernet MAC addresses.

Computers can connect to FCoE with converged network adapters (CNAs), which contain both Fibre Channel host bus adapter
