    摘要: An apparatus for estimating an effective bandwidth of a traffic stream (1, 21) of data packets in a packet network contains a buffer model (2, 23) which is fed by a copy of said traffic stream (1', 21') and which is drained at an adaptive service rate (7, 27) and a control device (5, 25) connected to said buffer model (2, 23) to register overflow events of said buffer model (2, 23) and adapted to tune the service rate (7, 27) such that a packet loss rate corresponding to said overflow events equals a preset target loss rate.

    摘要: The invention concerns a method for determining a path quality in a packet based communication network (100). The invention concerns also a quality accounting unit (10q) and a corresponding output line card (100). The quality accounting unit (10q) measures data rate (d i ) associated with the data traffic transmitted through a link (111) of the communication network (100) at an output line card (100) of a node (1) of the communication network (100). The quality accounting unit (10q) determines a hypothetical drop probability (P 1 ) of data transmitted through the link (111) based on the measured data rate (d i ) and data extracted from a data base (10qt), the path quality being specified by the hypothetical drop probability (P 1 ).

    摘要: The invention concerns a method of controlling a packet transmission, and a sender and a computer program product to execute said method. A packet transmission in a packet switched network (6) via a link (8) between a sender (2) receiving a packet traffic and a receiver (4) at a transmission bit rate (R) is controlled. A traffic offer to the sender (2) is predicted on at least one time scale. Based on the prediction, a target transmission bit rate which is adapted to the predicted traffic offer is determined. The transmission bit rate (R) is changed to the target transmission bit rate at a change rate defined so that a clock recovery (42) of the receiver (4) remains phase-locked to the changing transmission bit rate.

    摘要: The invention relates to a method for transmitting one or more client signals via a burst or frame switched network. According to the method, packets 30a, 30b, 30c of the one or more client signals are received at an ingress node of the network. Timing information characterizing the timing of the received packets 30a, 30b, 30c is determined and the received packets 30a, 30b, 30c are mapped into a container 33. The container 33 and the timing information are transmitted via the network. At an egress node of the network, the packets 30a, 30b, 30c are extracted from the container and the packets 30a, 30b, 30c are timed for further transmission based on the transmitted timing information.
