FIELD: communication networks.
SUBSTANCE: in accordance to the invention, unit in a network, such as a router, transmits at least one data stream, containing a set of data packets, into second unit; data streams may be associated with corresponding voice calls, which should be transferred through network. Frequency band usage coefficient is determined between first unit and second unit, and control packets are transmitted from first unit to second unit at speed, which is function of frequency band usage coefficient, and speed is reversely proportional to coefficient of frequency band usage. In second unit network overload may be determined on basis of speed, at which control packets are received and, if overload exceeds set threshold, setup of new voice calls through second unit and in the network may be limited.
EFFECT: improved network overload limiting.
