EtherFast® Series
DVMRP
Dynamic Routing - The ability for a router to forward data via a different route based on the current conditions of the communications circuits. For example, it can adjust for overloaded traffic or failing lines and is much more flexible than static routing, which uses a fixed forwarding path.
Ethernet - IEEE standard network protocol that specifies how data is placed on and retrieved from a common transmission medium. Has a transfer rate of 10Mbps. Forms the underlying transport vehicle used by several
Fast Ethernet - A 100 Mbps technology based on the
Full Duplex - The ability of a device or line to transmit data simultaneously in both directions.
GARP (General Attributes Registration Protocol) - A standard for registering or deregistering client attributes for client services within a bridged LAN.
GMRP (GARP Multicast Registration Protocol) - Allows network devices to register endstations with multicast groups. GMRP requires that any participat- ing network devices or endstations comply with the IEEE 802.1p standard.
GVRP (GARP VLAN Registration Protocol) - Defines a way for switches to exchange VLAN information in order to register VLAN members on ports across the network.
Half Duplex - Data transmission that can occur in two directions over a single line, but only one direction at a time.
Hardware - Hardware is the physical aspect of computers, telecommunications, and other information technology devices. The term arose as a way to distinguish the “box” and the electronic circuitry and components of a computer from the pro- gram you put in it to make it do things. The program came to be known as the soft- ware.
Hub - The device that serves as the central location for attaching wires from workstations. Can be passive, where there is no amplification of the signals; or active, where the hubs are used like repeaters to provide an extension of the cable that connects to a workstation.

IEEE - The Institute of Electrical and Electronics Engineers. The IEEE describes itself as “the world’s largest technical professional
The IEEE fosters the development of standards that often become national and international standards. The organization publishes a number of journals, has many local chapters, and has several large societies in special areas, such as the IEEE Computer Society.
IGMP (Internet Group Management Protocol) - A multicast host registration protocol that allows any host to inform its local router that it wants to receive transmissions addressed to a specific multicast group.
LAN - A local area network (LAN) is a group of computers and associated devices that share a common communications line and typically share the resources of a single processor or server within a small geographic area (for example, within an office building).
Latency - The time delay between when the first bit of a packet is received and the last bit is forwarded.
Layer 2 - Data Link layer in the ISO
Layer 3 - Network layer in the ISO
MAC Address - The MAC (Media Access Control) address is your computer’s unique hardware number.
Mbps (MegaBits Per Second) - One million bits per second; unit of measure- ment for data transmission.
Multicast Routing Protocol - A routing protocol that supports multicast pack- ets (one to many).
Multicasting - Sends data to a group of nodes instead of a single destination.
