Node (networking) In telecommunications networks, a node ( Latin: nodus, ‘knot’) is either a redistribution point or a communication endpoint. A physical network node is an electronic device that is attached to a network, and is capable of creating, receiving, or transmitting information over a communication channel. [1] In data ...
A telecommunications network is a group of nodes interconnected by telecommunications links that are used to exchange messages between the nodes. The links may use a variety of technologies based on the methodologies of circuit switching , message switching , or packet switching , to pass messages and signals.
Network topology is the topological [4] structure of a network and may be depicted physically or logically. It is an application of graph theory [3] wherein communicating devices are modeled as nodes and the connections between the devices are modeled as links or lines between the nodes. Physical topology is the placement of the various ...
Node B is the telecommunications node for mobile communication networks, namely those that adhere to the UMTS standard. The Node B provides the connection between mobile phones ( UEs) and the wider telephone network. UMTS is the dominating 3G standard. Node B corresponds to BTS ( base transceiver station) in GSM .
The Intelligent Network ( IN) is the standard network architecture specified in the ITU-T Q.1200 series recommendations. [1] It is intended for fixed as well as mobile telecom networks. It allows operators to differentiate themselves by providing value-added services in addition to the standard telecom services such as PSTN, ISDN on fixed ...
A cellular network or mobile network is a telecommunications network where the link to and from end nodes is wireless and the network is distributed over land areas called cells, each served by at least one fixed-location transceiver (typically three cell sites or base transceiver stations ). These base stations provide the cell with the ...
In telecommunications, node-to-node data transfer [1] is the movement of data from one node of a network to the next. In the OSI model it is handled by the lowest two layers, the data link layer and the physical layer . In most communication systems, the transmitting point applies source coding, [2] followed by channel coding, and lastly, line ...
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.
