US Patent:

51722593, Dec 15, 1992

Filed:

Feb 27, 1991

Appl. No.:

7/661762

Inventors:

Thomas J. Cloonan - Downers Grove IL
John R. Erickson - Grover MO
Anthony L. Lentine - St. Charles IL
Frederick B. McCormick - Lisle IL
Gaylord W. Richards - Lisle IL

Assignee:

AT&T Laboratories - Murray Hill NJ

International Classification:

H04J 1408

US Classification:

359139

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.

International Classification:

H04J 1400

US Classification:

359117

Abstract:

A network arrangement and control method where, before any transmission of data occurs for a particular communication, a network controller determines an unused path to provide a connection, advantageously all the way through the network from a given inlet to a given outlet. Once the identity of the unused path is known, the controller determines control information for use in activating that path and transmits that control information into the network, significantly via the network inlets. The network responds by activating the determined path and communication is enabled via the activated path, but only for the single connection and no buffering of information is required within the network. The network is particularly well suited for optical implementation and control is effected without the use of spatial light modulators but rather by means of control elements embedded within the network itself.
