Abstract: A flow of ATM cells to be cross-connected performs two consecutive passes through the connection network (PX) of a node. In the first pass the virtual channels of the input virtual paths (A, B, C) are distributed among intermediate virtual channel bundles (A'...C''') each with an overall peak bandwidth equal to that of the virtual path of origin of its contributing channels; between the first and the second pass, the virtual channels are cross-connected and the related cells are temporarily memorized, and at the same time the cell flow to be associated to an output virtual path is shaped; and in the second pass the virtual paths are cross-connected, Temporary memorization and shaping are accomplished in a device (SMS) connected between the outputs and the inputs of the connection network (PX) of the node.
