Abstract:
1. A networking device comprising: a media access controller; a first rate adaptation layer configured to communicate with the media access controller; a first physical extension module configured to communicate with the first rate adaptation layer; a second physical extension module configured to communicate with the first physical extension module using a physical extension interface; a second rate adaptation layer configured to communicate with the second physical extension module; and a physical layer device configured to communicate with the second rate adaptation layer using an extended 10 Gbps media independent interface (EXGMII), wherein the EXGMII includes a plurality of signal interconnections, a first mapping of signals of a media independent interface (MII) to the plurality of signal interconnections, a second mapping of signals of a 1 Gbps MII (GMII) to the plurality of signal interconnections, and a third mapping of signals of a 10 Gbps MII (XGMII) to the plurality of signal interconnections.
