Metcalfe's law. Two telephones can make only one connection, five can make 10 connections, and twelve can make 66 connections. Metcalfe's law states that the financial value or influence of a telecommunications network is proportional to the square of the number of connected users of the system (n 2). The law is named after Robert Metcalfe and ...
Network throughput (or just throughput, when in context) refers to the rate of message delivery over a communication channel, such as Ethernet or packet radio, in a communication network. The data that these messages contain may be delivered over physical or logical links, or through network nodes. Throughput is usually measured in bits per ...
Telecommunications network. 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.
A backhaul of a mobile network, also referred to as a mobile-backhaul connects a cell site towards the core network. The two main methods of mobile backhaul implementations are fiber-based backhaul and wireless point-to-point backhaul. [2] Other methods, such as copper-based wireline, satellite communications and point-to-multipoint wireless ...
Network science. Network topology is the arrangement of the elements (links, nodes, etc.) of a communication network. [1][2] Network topology can be used to define or describe the arrangement of various types of telecommunication networks, including command and control radio networks, [3] industrial fieldbusses and computer networks.
Plesiochronous digital hierarchy. The plesiochronous digital hierarchy (PDH) is a technology used in telecommunications networks to transport large quantities of data over digital transport equipment such as fibre optic and microwave radio systems. [ 1 ] The term plesiochronous is derived from Greek plēsios, meaning near, and chronos, time ...
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 ...
Point code. An SS7 point code is an address for the SS7 telephone switching system. It is similar to an IP address in an IP network. It is a unique address for a node (Signaling Point, or SP), used in MTP layer 3 to identify the destination of a message signal unit (MSU). Message contain an OPC (Originating Point Code) and a DPC (Destination ...
