Fast Ethernet An Ethernet system that is designed to operate at 100 Mbps. Gigabit Ethernet An Ethernet system that is designed to operate at 1000 Mbps. 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. Half Duplex A system that allows packets to be transmitted and received, but not at the same time. Half duplex is not supported for 1000 Mbps. Contrast with full duplex. IEEE Institute of Electrical and Electronics Engineers. This American organization was founded in 1963 and sets standards for computers and communications. IEEE 802.1D Specifies a general method for the operation of MAC bridges, including the Spanning Tree Protocol. 65 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 802.3ad A standard that defines link aggregation. 802.3ad is now incorporated into the relevant sections of the IEEE Std. 802.3-2002. 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.
