Distributed switching is an architecture in which multiple processor-controlled switching units are distributed. There is often a hierarchy of switching elements, with a centralized host switch and with remote switches located close to concentrations of users. Distributed switching is often used in telephone networks, though it is often called host-remote switching. In rural areas, population centers tend to be too small for economical deployment of a full-featured dedicated telephone exchange, and distances between these centers make transmission costs relatively high. Normal telephone traffic patterns show that most calling is done between people in a community of interest, in this case a geographical one: the population center.
