Spoke–hub distribution paradigm

The spoke–hub distribution paradigm (also known as the hub-and-spoke system) is a form of transport topology optimization in which traffic planners organize routes as a series of "spokes" that connect outlying points to a central "hub". Simple forms of this distribution/connection model contrast with point-to-point transit systems, in which each point has a direct route to every other point, and which modeled the principal method of transporting passengers and freight until the 1970s. Delta Air Lines pioneered the spoke–hub distribution model in 1955. In the late 1970s the telecommunications and information technology sector subsequently adopted this distribution topology, dubbing it the star network network topology.

"Hubbing" involves "the arrangement of a transportation network as a hub-and-spoke model".
