Fibre Channel Over Ethernet

FCoE is an ANSI T11 standard for the encapsulation of a complete Fibre Channel
frame into an Ethernet frame. The resulting Ethernet frame is transported over
Enhanced Ethernet networks as shown in
mapping technologies, FCoE has the least mapping overhead and maintains the
same constructs as native Fibre Channel, thus operating with native Fibre
Channel management software. FCoE is based on lossless Ethernet to enable
buffer-to-buffer credit management and flow control of Fibre Channel packets.
