<P> Data centers used Ethernet for TCP / IP networks and Fibre Channel for storage area networks ( SANs ) . With FCoE , Fibre Channel becomes another network protocol running on Ethernet , alongside traditional Internet Protocol ( IP ) traffic . FCoE operates directly above Ethernet in the network protocol stack , in contrast to iSCSI which runs on top of TCP and IP . As a consequence , FCoE is not routable at the IP layer , and will not work across routed IP networks . </P>
