What exactly is Fibre Channel over Ethernet?

What Fibre Channel over Ethernet (FCoE) does is pick up everything from Fibre Channel except the cabling and the physical interface. It picks up all the upper-level protocols, all the data integrity checks and all the flow control and grafts them onto Ethernet. Not onto IP, not onto TCP/IP — picking up Fibre Channel and placing it right on top of an enhanced Ethernet. While FCoE is based on Ethernet, it’s an enhanced Ethernet that has been optimized for low latency, quality of service, guaranteed delivery and other functionality traditionally associated with a channel-type interface like parallel SCSI, Fibre Channel, FICON or ESCON.
