摘要： The present invention provides an optoelectronic switch for transferring an optical signal from an input device to an output device, the optoelectronic switch including an array of interconnected switch modules, which are interconnected by an interconnecting fabric. The switch modules are arranged in an N-dimensional array, the ith dimension having a size Ri (i=1, 2, . . . , N), each switch module having an associated set of coordinates giving its location with respect to each of the N dimensions. Each switch module is a member of N such sub-arrays Si, each sub-array Si comprising Ri switch modules whose coordinates differ only in respect of their location in the ith dimension, and each of the N sub-arrays being associated with a different dimension.

摘要： A system and method for routing. A packet includes a stack of one or more headers, such as a stack of Multiprotocol Label Switching headers, that determines the path that the packet will take, through a sequence of switches, from its source to its destination. Each header in the stack contains an output port identifier that identifies an output port of a corresponding switch in the path. Each switch, upon receiving the packet, removes the first header to form a shortened packet, and routes the shortened packet to the output port identified by the output port identifier.
