For example, the sample diagram does not indicate the physical type of connection between the PCs and the switch, but since a modern LAN is depicted, Ethernet may be assumed. If the same style of line was used in a WAN (wide area network) diagram, however, it may indicate a different type of connection.
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.
A computer network is a set of computers sharing resources located on or provided ... where each client connects to a central network switch, ... Network diagram ...
A network's physical topology is a particular concern of the physical layer of the OSI model. Examples of network topologies are found in local area networks , a common computer network installation. Any given node in the LAN has one or more physical links to other devices in the network; graphically mapping these links results in a geometric ...
It is a 12,000-mile high-speed national computer network owned and operated by the US research and education community that runs over fiber-optic lines. It was the first transcontinental 10 Gigabit Ethernet network. It operates with an aggregate capacity of up to 1.6 Tbit/s and a 40 Gbit/s bitrate. [255] [256] NLR ceased operations in March 2014.
A multilayer switch (MLS) is a computer networking device that switches on OSI layer 2 like an ordinary network switch and provides extra functions on higher OSI layers.The MLS was invented [1] by engineers at Digital Equipment Corporation.
Multiprotocol Label Switching (MPLS) is a routing technique in telecommunications networks that directs data from one node to the next based on labels rather than network addresses. [1] Whereas network addresses identify endpoints, the labels identify established paths between endpoints.
Circuit switching originated in analog telephone networks where the network created a dedicated circuit between two telephones for the duration of a telephone call. [2] It contrasts with message switching and packet switching used in modern digital networks in which the trunklines between switching centres carry data between many different ...
