Gateway
A networking device that connects networks that are using different network protocols. A product that enables two dissimilar networks to communicate or interface with each other. In the IP community, an older term referring to a routing device. Today, the term “router” is used to describe nodes that perform this function, and “gateway” refers to a specialpurpose device that performs an application layer conversion of information from one protocol stack to another. Compare with router. Interface providing a compatibility between networks by converting transmission speeds, protocols, codes, or security measures.

(1) A system responsible for making decisions about which of several paths network (or Internet) traffic will follow. To do this, it uses aA network device used to control traffic flow on networks. Routers are often used to connect similar networks together and control traffic flow between them. They can function using statically defined routing tables or employ a dynamic routing system.

A device that propagates electrical signals from one cable to another without making routing decisions or providing packet filtering. In OSI terminology, a repeater is a physical layer intermediate system. See bridge, router. A network device used to amplify signals on network cabling to allow for longer distances between nodes. Also known as a concentrator or amplifier.

The emerging layer 3 switching technology integrates routing with switching to yield very high routing throughput rates in the millionsofpacketspersecond range. The movement to layer 3 switching is designed to address the downsides of the current generation of layer 2 switches, which are functionally equivalent to bridges. These downsides for a large, flat network include being subject to broadcast storms, spanning tree loops, and address limitations that drove the injection of routers into bridged networks in the late 1980s. Currently, layer 3 switching is represented by a number of approaches in the industry.

Authentication protocol that allows PPP peers to authenticate one another. The remote router attempting to connect to the local router is required to send an authentication request. Unlike CHAP, PAP passes the password and hostname or username in the clear (unencrypted). PAP does not itself prevent unauthorized access, but merely identifies the remote end. The router or access server then determines if that user is allowed access. PAP is supported only on PPP lines. Compare with CHAP.
