Abstract
Variable length LAN frames can be segmented into fixed length cells to allow the data in the frames to be transported through an intermediate cell-based system, such as an ATM network. Where transport through the intermediate system results in time gaps between data units extracted from the cells, special symbol combinations can be inserted into the time gaps to permit frame-representing data to be forwarded toward its destination as a 'stretched frame' without waiting for all the cells representing the frame to arrive. When a stretched LAN frame is received at a 'stretch-aware' LAN station, the special symbol combinations are detected and removed to recover at least the data payload of the original LAN frame.
