Abstract

To eliminate transmission latency due to the header of an IP packet, ATM cell or Ethernet frame, the header of the packet or frame is transmitted a set time before the data to be transmitted in the body of the packet or cell is due to be available for transmission, the set time corresponding precisely to the header transmission time. The packet data may comprise PCM voice information, or video data.
