- Routing
(n.) In internetworking, the process of moving a packet of data from source to destination. Routing is usually performed by a dedicated device called a router. Routing is a key feature of the Internet because it enables messages to pass from one computer to another and eventually reach the target machine. Each intermediary computer performs […]
- routing information field
(n.) In token-ring networks, the optional field at the end of a MAC header right before the user data that contains the routing information. Routing bridges use this data to determine where to route tokens when sending data from one token-ring network to another interconnected token-ring network. The routing information field typically contains a series […]
- routing protocol
A generic term that refers to a formula, or protocol, used by a router to determine the appropriate path over which data is transmitted. The routing protocol also specifies how routers in a network share information with each other and report changes. The routing protocol enables a network to make dynamic adjustments to its conditions, […]
- routing metric
A variable used by a dynamic router to calculate its routing table. This determines which route the router should use to forward a packet.
- routing switch
(n.) A switch that also performs routing operations. Usually a switch operates at layer 2 (the Data Link layer) of the OSI Reference Model while routers operate at layer 3 (the Network layer). Routing switches, however, perform many of the layer 3 functions usually reserved for routers. And because the routing is implemented in hardware […]
