filtering
The process of screening a packet for certain characteristics, such as
source address, destination address, or protocol. Filtering is used to
determine whether traffic is to be forwarded, and can also prevent
unauthorized access to a network or network devices.
flow control
A congestion control mechanism. Congestion is caused by devices
sending traffic to already overloaded port on a Switch. Flow control
prevents packet loss and inhibits devices from generating more traffic
until the period of congestion ends.
full duplex
A system that allows packets to be transmitted and received at the
same time and, in effect, doubles the potential throughput of a link.
GARP
Generic Attribute Registration Protocol. A system outlined by the IEEE
802.1D standard that allows endstations in a network to register that
they would like to receive traffic with certain attributes.
GMRP
GARP Multicast Registration Protocol. A specific use of GARP that
allows endstations to register that they would like to receive traffic
from certain multicast groups.
GVRP
GARP VLAN Registration Protocol. A specific use of GARP that allows
endstations to register that they would like to receive traffic for certain
VLANs.
half duplex
A system that allows packets to transmitted and received, but not at
the same time. Contrast with
full duplex
.
hub
A device that regenerates LAN traffic so that the transmission distance
of that signal can be extended. Hubs are similar to repeaters, in that
they connect LANs of the same type; however they connect more LANs
than a repeater and are generally more sophisticated.
IEEE
Institute of Electrical and Electronics Engineers. This American
organization was founded in 1963 and sets standards for computers
and communications.
IEEE 802.1D
A standard that defines the behavior of bridges in an Ethernet network.
IEEE 802.1p
A standard that defines GMRP and traffic prioritization.
IEEE 802.1Q
A standard that defines VLAN tagging and GVRP.
IEEE 802.3x
A standard that defines a system of flow control for ports that operate
in full duplex.
