BACKGROUND In the field of optical communication networks, it is con ventional to use an
optical Switch to Switch paths for an optical packet transmitted from a transmission source …

An optical switch section that switches the path of an optical packet transmitted thereto and
outputs the optical packet, and a control section that generates multiple switch control …

Asynchronous optical data is aligned with synchronous convergence points in an optical
packet switching system. The convergence points can be any place where data enters an …

An optical switching device the size and costs of which are reduced by decreasing the
number of switching elements and which can flexibly accommodate the expansion of the …

Caccuro (57) ABSTRACT An optical packet switch which receives data packets and
switches those data packets in the optical domain without using recirculation devices is …

Optical Switches are provided in an optical transmission System having at least two optical
nodes in optical commu nication over a primary optical path and a backup optical path. An …

In a method of controlling a switching operation of an optical network for use in connection
between an optical transmitter and an optical receiver through an optical switch is controlled …

The present invention provides means by which a switch controller that manages lines
directly notifies receivers of ineffectiveness of received data upon line disconnection instead …
