Routing

From Wikipedia, the free encyclopedia

This article is about routing in computer networks. For other uses, see Routing (disambiguation).Routing (or routeing) is the process of selecting paths in a network along which to send data or physical traffic. Routing is performed for many kinds of networks, including the telephone network, the Internet, and transport networks.
Routing directs forwarding, the passing of logically addressed packets from their source toward their ultimate destination through intermediary nodes; typically hardware devices called routers, bridges, gateways, firewalls, or switches. Ordinary computers with multiple network cards can also forward packets and perform routing, though they are not specialized hardware and may suffer from limited performance. The routing process usually directs forwarding on the basis of routing tables which maintain a record of the routes to various network destinations. Thus constructing routing tables, which are held in the routers' memory, becomes very important for efficient routing.
Routing, in a more narrow sense of the term, is often contrasted with bridging in its assumption that network addresses are structured and that similar addresses imply proximity within the network. Because structured addresses allow a single routing table entry to represent the route to a group of devices, structured addressing (routing, in the narrow sense) outperforms unstructured addressing (bridging) in large networks, and has become the dominant form of addressing on the Internet, though bridging is still widely used, albeit within localized environments.

Network Basic Hardware Components

Komponen Dasar Perangkat Keras Jaringan

Semua jaringan terdiri dari perangkat keras blok pembangun interkoneksi nodes jaringan, seperti misalkan Network Interface Cards (NICs), Bridges, Hubs, Switches, dan Routers. Sebagai tambahan, beberapa cara penghubungan diperlukan untuk menghubungkan blok kesatuan ini, biasanya dalam bentuk kabel galvanic (paling sering termasuk Kabel kategori 5). Yang agak jarang adalah sambungan Gelombang Micro (seperti pada IEEE 802.11) atau Kabel Optik ("optical fiber").


Network Basic Hardware Components

All networks are made up of basic hardware building blocks to interconnect network nodes, such as Network Interface Cards (NICs), Bridges, Hubs, Switches, and Routers. In addition, some method of connecting these building blocks is required, usually in the form of galvanic cable (most commonly Category 5 cable). Less common are microwave links (as in IEEE 802.11) or optical cable ("optical fiber").
