发明名称 Method for multi-address transmission of cells in a switching structure of a communication system operating in the asynchronous transfer mode
摘要 A method for multi-addressed transmission of cells in a switching structure of a communication system operating in the asynchronous transfer mode. Instead of internal routing information (ri) for non-multi-addressed cells (Z), row index information (zi) and multi-addressing information (rsi) are inserted into an internal cell header (IKZ) of the communication system of multi-addressed cells (RZ). After the reception of a multi-addressed cell (RZ) in a switching element (KE) of the switching structure, a prescribed row (Z1 . . .Zn) of a multi-addressing matrix (RSM), that is provided with routing information (kri) that is individually associated to switching elements, is identified with the assistance of the row index information (ZI). The switching paths of the multi-addressed cell (RZ) in the respective switching element (KE) are defined by the routing information (kri) individually associated to the switching elements. The routing information (kri), that is individually associated to the switching elements and is formed of path information (wi) and of row index or cell routing information (zi, zri), is calculated by a communication system controller (ST) with the assistance of the subscriber signalling information and is entered into the multi-addressing matrix (RSM). In this method the structure of the internal cell header (IKZ) of the communication system is preserved.
