Glossary Ethernet Fast Ethernet Gigabit Ethernet Fault isolation Forwarding Filtering Flow control Full-duplex Half-duplex IEEE IETF IP IP address LAN A LAN specification developed jointly by Xerox, Intel and Digital Equipment Corporation. Ethernet networks transmit packets at a rate of 10 Mbps. An Ethernet system that is designed to operate at 100 Mbps. An Ethernet system that is designed to operate at 1000 Mbps (1 Gbps). A technique for identifying and alerting administrators about connections (such as those associated with switch ports) that are experiencing congestion or failure, or exceeding an administrator-defined threshold. The process of sending a packet toward its destination using a networking device. 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. A congestion- control mechanism. Congestion is caused by devices sending traffic to already overloaded port on a switch. Flow control prevents packet loss and temporarily inhibits devices from generating more traffic until the period of congestion ends. A system that allows packets to be transmitted and received at the same time and, in effect, doubles the potential throughput of a link. A system that allows packets to transmitted and received, but not at the same time. Contrast with full duplex. Institute of Electrical and Electronics Engineers. This American organization was founded in 1963 and sets standards for computers and communications. 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. Internet Protocol. IP is a layer 3 network protocol that is the standard for sending data through a network. IP is part of the TCP/IP set of protocols that describe the routing of packets to addressed devices. Internet Protocol address. A unique identifier for a device attached to a network using TCP/IP. The address is written as four octets separated with periods (full-stops), and is made up of a network section, an optional subnet section and a host section. Local Area Network. A network of endstations (such as PCs, printers, servers) and network devices (hubs and switches) that cover a relatively small geographic area (usually not larger than a floor or building).
