A forwarding information base (FIB), also known as a forwarding table or MAC table, is most commonly used in network bridging, routing, and similar functions to find the proper output network interface controller to which the input interface should forward a packet. It is a dynamic table that maps MAC addresses to ports.
If properly configured, the PC can also function as the router for a home LAN. An internal modem can be installed on a single PC (e.g. on a PCI card), also allowing that single PC to connect to a WAN. [7] Again, the PC can be configured to function as a router for a home LAN. A cellular wireless access point can function in a similar fashion to ...
A routing table usually consists of a list of possible destination networks or IP addresses for which the next hop is known. By only storing next-hop information, next-hop routing or next-hop forwarding reduces the size of routing tables. A given gateway only knows one step along the path, not the complete path to a destination.
A network switch (also called switching hub, bridging hub, Ethernet switch, and, by the IEEE, MAC bridge [1]) is networking hardware that connects devices on a computer network by using packet switching to receive and forward data to the destination device.
Cisco VIP 2-40, from an older generation of routers. Performance Route Processor, from the high-end Cisco 12000 series.. In routing, the data plane, sometimes called the forwarding plane or user plane, defines the part of the router architecture that decides what to do with packets arriving on an inbound interface.
Historically, the main reason for purchasing hubs rather than switches was their price. By the early 2000s, there was little price difference between a hub and a low-end switch. [11] Hubs can still be useful in special circumstances: For inserting a protocol analyzer into a network connection, a hub is an alternative to a network tap or port ...
