We present an efficient cell multiplexing method, called longest delay beyond expectation (LDBE), to schedule real-time traffic in ATM networks. By arranging cell transmission orders, the LDBE scheme can minimize the cell delay variation (CDV), reduce the cell loss ratio (CLR) and avert the excess of cell transfer delay (CTD) bounds, particularly when different CDV tolerance (CDVT) values are applied at each node along the path of a connection. Simulation results demonstrate that the proposed LDBE performs better than some prominent multiplexing methods in terms of these quality of service (QoS) requirements. Furthermore, the LDBE proposed is extended to handle both real-time and non-real-time traffic
