Routing calculates good paths through a network for information to take. For example, from node 1 to node 6 the best routes are likely to be 1-8-7-6, 1-8-10-6 or 1-9-10-6, as these are the shortest routes.
Partial map of the Internet, based on the January 15, 2005 data found on opte.org . Each line is drawn between two nodes, representing two IP addresses. The length of the lines is indicative of the delay between those two nodes. This graph represents less than 30% of the Class C networks reachable.

Broadly, routing is performed in many types of networks, including circuit-switched networks, such as the public switched telephone network (PSTN), and computer networks, such as the Internet.

A network switch (also called switching hub, bridging hub, and, by the IEEE, MAC bridge ) is networking hardware that connects devices on a computer network by using packet switching to receive and forward data to the destination device.

Some switches can also forward data at the network layer (layer 3) by additionally incorporating routing functionality.

A high-level overview of network bridging, using the ISO/OSI layers and terminology

Bridging is distinct from routing.

Shortest Path Bridging (SPB), specified in the IEEE 802.1aq standard and based on Dijkstra's algorithm, is a computer networking technology intended to simplify the creation and configuration of networks, while enabling multipath routing.

Network packet

In telecommunications and computer networking, a network packet is a formatted unit of data carried by a packet-switched network.

The routing of network packets requires two network addresses, the source address of the sending host, and the destination address of the receiving host.

Routing protocol classification computer networks.

A routing protocol specifies how routers communicate with each other to distribute information that enables them to select routes between nodes on a computer network.

Routing algorithms determine the specific choice of route.

Routing table

0 links

In computer networking, a routing table, or routing information base (RIB), is a data table stored in a router or a network host that lists the routes to particular network destinations, and in some cases, metrics (distances) associated with those routes.

This forwarding table contains only the routes which are chosen by the routing algorithm as preferred routes for packet forwarding.

A multicast forwarding pattern, typical of PIM
A broadcast forwarding pattern, typical of bridged Ethernet

Packet forwarding is the relaying of packets from one network segment to another by nodes in a computer network.

The forwarding decision is generally made using one of two processes: routing, which uses information encoded in a device's address to infer its location on the network, or bridging, which makes no assumptions about where addresses are located and depends heavily on broadcasting to locate unknown addresses.

Multipath routing

Multipath routing is a routing technique simultaneously using multiple alternative paths through a network.

In networking and in graph theory, capillary routing, for a given network, is a multi-path solution between a pair of source and destination nodes.
