Abstract:
A method of transferring data from a packet-switched data communications network which uses data packets of a first size to a further packet-switched data communications network which uses data packets of a second size generally different to said first size, comprising the steps of:queuing input data packets of said first size;processing the data payloads of said input data packets received from said queue to line-encode said data so that it may be transmitted in said data packets of said second size;generating output processed data packets of the same size as the input data packets of said first size for transmitting said processed data payloads to a first to second size data packets conversion device;wherein the generating step comprises holding any input data packet of said first size in said input queue until all its data payload has been processed and passed into an output processed data packet and reprocessing the input data packet in the event that not all of its data payload has been so passed whereby the remainder of the data payload of said held packet is passed to the next output processed data packet, wherein the reprocessing step includes inhibiting any previously passed data from being placed into the next output processed data packet to prevent the erroneous duplication of said processed data.
