Abstract
There is provided a packet-rate control method for a packet network, in which a declaration of parameters indicating the rate of fixed-length packets is so made to a call control system by a subscriber terminal device prior to communication as to be associated with a logical channel number. The rate of packets inputted to the network is so measured as to be associated with a logical channel number. While the degree of violation is low, packets transmitted in violation of user-declaring parameters are provided with a violation mark and taken in the network. If the degree of violation is high, the packets transmitted in violation of user-declaring parameters are discarded on the input side of the network. When there appears a possibility of congestion in the network, the marked packets are discarded. As a result, it is possible to prevent violation packets and marked packets from affecting the quality of service using normal packets.
