Abstract With the widespread use of high‐speed broadband communication, nonblocking switching networks in video distribution and other applications for the broadcast distribution connection will be required. Numerous studies have been made of performance analysis for switching networks for one‐to‐one switching connections, but it is anticipated that a future study is needed for one‐to‐many switching connections. This paper presents a construction for the copy distribution stage, which copies the cell for the broadcast distribution. The copy distribution stage is composed of a multistage connection network. The basic principle of operation is that the cells are arranged appropriately and are copied by the differential address driving. The proposed network is suited to high‐speed operation since nonblocking self‐routing is realized and the control logic is simple. The proposed network assumes that it precedes the network for one‐to‐one switching connection. Then one‐to‐many broadcast distribution connection is realized.
