Gigabit Ethernet layers have been defined by adaptation of the LLC and MAC layers of classical Ethernet and the physical layers of the ANSI Fiber Channel technology. A so-called reconciliation layer is used in between for seamless interoperation. The physical layer of the Fiber Channel technology uses 8B10B block coding.
