Abstract:
1. A telecommunications switch comprising: an optical switch coupled to a plurality of optical inputs and a plurality of optical outputs; a switch controller being coupled to the optical switch, the switch controller operating the optical switch with a schedule not directly determined by an input stream of data units; a plurality of reordering units coupled to the optical switch through an electrical-optical converter, the plurality of reordering units buffering data units of received data streams into queues for each input/output pair of the optical switch and rearranging the order of the data units within the data streams to correspond to the schedule of the switch; and the switch controller changing the schedule of the optical switch to have unbalanced periods in response to unbalance in traffic, the schedule being changed in response to information provided by the plurality of reordering units regarding the number of reordered data units in the queues for each input/output pair.
