  • Patent number: 11005768
    Abstract: The invention sets out a method where a critical loading related to jitter associated with a link between the access point and a client device is determined. This critical load is the load beyond which retransmissions are insufficient for the client device to repair the video stream. The critical load is determined by sending data at varying transmission rates during a calibration mode, and measuring the jitter and packet loss rate. A safe load is then set as a fraction of this critical load. The loading associated with a multicast stream is then monitored with reference to this safe load, and if the safe load is met or exceeded, then action is taken to avoid packet loss increasing to a critical level. One action may be to adjust the transmission rate of the multicast stream for example, such that the load is reduced to below the safe load level.
