Star topology in use in a network. A star network is an implementation of a spoke–hub distribution paradigm in computer networks. In a star network, every host is connected to a central hub. In its simplest form, one central hub acts as a conduit to transmit messages. [1] The star network is one of the most common computer network topologies.
The star network, a computer network modeled after the star graph, is important in distributed computing. A geometric realization of the star graph, formed by identifying the edges with intervals of some fixed length, is used as a local model of curves in tropical geometry. A tropical curve is defined to be a metric space that is locally ...
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.
Early repeaters had only two ports, allowing, at most, a doubling of network size. Once repeaters with more than two ports became available, it was possible to wire the network in a star topology. Early experiments with star topologies (called Fibernet) using optical fiber were published by 1978. [41]
The physical or geographic locations of network nodes and links generally have relatively little effect on a network, but the topology of interconnections of a network can significantly affect its throughput and reliability. With many technologies, such as bus or star networks, a single failure can cause the network to fail entirely.
For a network of n nodes, only n − 1 routes are necessary to connect all nodes so the upper bound is n − 1, and the complexity is O(n). That compares favourably to the () routes, or O(n 2), which would be required to connect each node to every other node in a point-to-point network. For example, in a system with 6 destinations, the spoke ...

A star topology, using a central uplink site, such as a network operations center (NOC), to transport data back and forth to each VSAT via satellite, A mesh topology, where each VSAT relays data via satellite to another terminal by acting as a hub, minimizing the need for a centralized uplink site, A combination of both star and mesh topologies.
