LOSSARY
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.
HTTP Hypertext Transfer Protocol. This is a set of rules for exchanging files
(text, graphic images, sound, video, and other multimedia files) on the
World Wide Web.
IEEE Institute of Electrical and Electronics Engineers. This American
organization was founded in 1963 and sets standards for computers
and communications.
IEEE Std 802.1D, 1998
Edition
A standard that defines the behavior of bridges in an Ethernet network.
IEEE Std 802.1p A standard that defines traffic prioritization. 802.1p is now
incorporated into the relevant sections of the IEEE Std 802.1D, 1998
Edition.
IEEE Std 802.1Q-1998 A standard that defines VLAN tagging.
IEEE Std 802.3ad A standard that defines link aggregation. 802.3ad is now incorporated
into the relevant sections of the IEEE Std 802.3-2002.
IEEE Std 802.3x A standard that defines a system of flow control for ports that operate
in full duplex. 802.3x is now incorporated into the relevant sections of
the IEEE Std 802.3-2002.
IEEE Std 802.1w-2001 A standard that defines Rapid Spanning Tree Protocol (RSTP) behavior.
IEEE Std 802.1X-2001 A standard that defines port-based network access control behavior.
IETF Internet Engineering Task Force. An organization responsible for
providing engineering solutions for TCP/IP networks. In the network
management area, this group is responsible for the development of the
SNMP protocol.
IGMP snooping A mechanism performed by an intermediate device, such as a Layer 2
Switch, that optimizes the flow of multicast traffic. The device listens
for IGMP messages and build mapping tables and associated
forwarding filters, in addition to reducing the IGMP protocol traffic.
