65Fast EthernetAn Ethernet system that is designed to operate at 100Mbps.Gigabit EthernetAn Ethernet system that is designed to operate at 1000Mbps.Full DuplexA system that allows packets to be transmitted andreceived at the same time and, in effect, doubles thepotential throughput of a link.Half DuplexA system that allows packets to be transmitted andreceived, but not at the same time. Half duplex is notsupported for 1000 Mbps. Contrast with full duplex.IEEEInstitute of Electrical and Electronics Engineers. ThisAmerican organization was founded in 1963 and setsstandards for computers and communications.IEEE 802.1DSpecifies a general method for the operation of MACbridges, including the Spanning Tree Protocol.IEEE 802.1QVLAN Tagging - Defines Ethernet frame tags which carryVLAN information. It allows switches to assignendstations to different virtual LANs, and defines astandard way for VLANs to communicate acrossswitched networks.IEEE 802.1pAn IEEE standard for providing quality of service (QoS) inEthernet networks. The standard uses packet tags thatdefine up to eight traffic classes and allows switches totransmit packets based on the tagged priority value.IEEE 802.3adA standard that defines link aggregation. 802.3ad isnow incorporated into the relevant sections of the IEEEStd. 802.3-2002.IETFInternet Engineering Task Force. An organizationresponsible for providing engineering solutions forTCP/IP networks. In the network management area, thisgroup is responsible for the development of the SNMPprotocol.
