Abstract: Ethernet local area network operation is specified for selected speeds of operation from 1 Mb/s to 10 Gb/s using a common media access control (MAC) specification@ management information base (MIB)@ and capability for Link Aggregation of multiple physical links into a single logical link. The Carrier Sense Multiple Access with Collision Detection (CSMA/CD) MAC protocol specifies shared medium (half duplex) operation@ as well as full duplex operation. Speed specific Media Independent Interfaces (MIIs) allow use of selected physical layer (PHY) interfaces for operation over coxial@ twisted pair or fiber optic cables. System considerations for multisegment shared access networks describe the use of Repeaters which are defined for operational speeds up to 1000 Mb/s. Local Area Network (LAN) operation is supported at all speeds. Other specified capabilities include: various PHY types for access networks@ PHYs suitable for metropolitian area network applications@ and the provision of power over selected twisted pair PHY types.
