Abstract
A network comprising a plurality of successively interconnected node stages where each node has an associated data connection state and includes a control element, significantly implemented as part of the node itself, for controlling the data connection state of at least one node of the following stage. The network is well suited for optical implementation and is controlled by shifting bits into the network for storage by the control elements rather than relying on spatial light modulators.
