Arrangement for realization of virtual shared medium for QoS in a communication network, at which a network unit (6) has an input port (1) and an output port (7) for two-way communication in a session, where each port (1, 7) includes a metering device (3, 10) arranged to meter data transmission speed, and an action device (4, 9), from a communication point of view connected to respective metering device (3, 10), and arranged to take/execute actions depending on the belonging metering device. The metering device (3) in said input port (1) is adapted to metering of data flows belonging to a first service, and the metering device (10) in said ouput port (7) is adapted to metering of data flows belonging to the same service, at which said output port (7) includes a calculation device ( SIGMA >0<) arranged to calculate control data depending on the metering device (3) in said input port (1) and the metering device (10) in said output port, and that the action device (9) in said output port (7) is arranged to, for said service, take/execute actions on the flow belonging to the service depending on said control data. Said control data is preferably the sum of data transmission speed of/for said service, metered by said metering device (3, 10) in said input port (1) and output port (7). |
