ABSTRACT:
A method and apparatus for synchronizing related data streams in interconnection networks. Some embodiments of an apparatus include a transmitter to transmit a data stream to a second apparatus, where the transmitter transmits a data packet to the second apparatus. The apparatus further includes a clock, with the apparatus providing a first timestamp for the data packet using the clock upon transmission of the data packet. The apparatus includes a receiver to receive responses from the second apparatus, with the apparatus providing a second timestamp upon receiving a returned packet from the second apparatus, with the returned packet containing timestamps for the receipt and transmission of the packet by the second apparatus. The apparatus includes a network unit to direct the operation of the apparatus, the network unit to determine a start time for decoding of the data stream by the second apparatus based at least in part on the timestamps for the packet.
