Description / Abstract:
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.
