83 QoS for realtime multimedia data every input port of a switch/router ends in one or more FiFo buffers every output port of a switch/router starts in one or more FiFo buffers backbone port always critical

84 Datagram Priorization realtime data needs QoS (speed) on its maximum file and database access needs reliability (database users may have another opinion) datagrams have to be classified this does not prevent network overload in total

85 Priorization Methods OSI level 2 priorization (datalink layer, IEEE protocol types) OSI level 3 priorization (network layer, Internet Protocol)
