operate on fiber, thin coax and twisted-pair
cable.
Fast Ethernet
A 100 Mbps network communication system
based on Ethernet and the CSMA/CD access
method.
Fast Ethernet Switch
Device that provides a full 100 Mbps
bandwidth (or either 10 or 100 Mbps
bandwidth with Auto-Negotiation) to each port
(LAN segment).
Full Duplex
Transmission method that enables switch and
network card to transmit and receive
concurrently, effectively doubling the
bandwidth of that link.
GARP VLAN Registration Protocol (GVRP)
Defines a way for switches to exchange
VLAN information in order to register
necessary VLAN members on ports along the
Spanning Tree so that VLANs defined in each
switch can work automatically over a
Spanning Tree network.
Generic Attribute Registration Protocol
(GARP)
GARP is a protocol that can be used by
endstations and switches to register and
propagate multicast group membership
information in a switched environment so that
multicast data frames are propagated only to
those parts of a switched LAN containing
registered endstations. Formerly called Group
Address Registration Protocol.
Gigabit Ethernet
A 1000 Mbps network communication system
based on Ethernet and the CSMA/CD access
method.
Group Attribute registration Protocol
See Generic Attribute Registration Protocol
IEEE 802.1D
Specifies a general method for the operation
of MAC bridges, including the Spanning Tree
Protocol.
IEEE 802.1Q
VLAN Tagging—Defines Ethernet frame tags
which carry VLAN information. It allows
switches to assign endstations to different
virtual LANs, and defines a standard way for
VLANs to communicate across switched
networks.
IEEE 802.1p
An IEEE standard for providing quality of
service (QoS) in Ethernet networks. The
standard uses packet tags that define up to
eight traffic classes and allows switches to
transmit packets based on the tagged priority
value.
IEEE 802.3
Defines carrier sense multiple access with
collision detection (CSMA/CD) access
method and physical layer specifications.
IEEE 802.3ab
Defines CSMA/CD access method and
physical layer specifications for 1000BASE-T
Gigabit Ethernet.
IEEE 802.3ac
Defines frame extensions for VLAN tagging.
IEEE 802.3u
Defines CSMA/CD access method and
physical layer specifications for 100BASE-TX
and 100BASE-FX Fast Ethernet.
IEEE 802.3x
Defines Ethernet frame start and stop
requests and timers used for flow control on
full-duplex links.
IEEE 802.3z
Defines CSMA/CD access method and
physical layer specifications for 1000BASE
Gigabit Ethernet.
