Abstract
An optical packet processor includes one or more optical packet inputs that receive asynchronous optical packets. An optical packet interconnect directs the optical packets from the different optical packet inputs to different optical packet outputs. The optical packets are buffered either before or after being directed from the inputs to the different outputs. Problems associated with optical buffering are overcome by synchronizing the asynchronous optical packets with the optical packet buffers. The novel optical buffer architectures described also reduce or eliminate the use of certain high cost optical components.
