DATA TRANSMISSION ON OPTICAL NETWORKS

摘要

In a system for transmitting data cells from a transmitter (1) to a receiver (2, 3) each cell comprises a fixed format header containing address information and a free format time slice of predetermined duration. The cells may be transmitted on an optical network (4) in which case the cells are routed by an optical switch (5) which reads the header and is transparent to the free format time slice. Second level cells are formed comprising a second level header and a time slice filled with a number of first level cells.
