ABSTRACT:
A switching system comprising a cross-point switch and a Delta network. The two switches are connected in parallel with common port adaptors. When a port desires a specified time reservation to another port, it sends a request message for the specified time over the Delta network to the requested adaptor at which a reservation processor grants a connection for completion at a fixed time in the future. The reservation grant is then returned via the Delta network to the requesting adaptor which, at the fixed time, sets the cross-point connection on the cross-point switch line associated with the requesting adaptor.
