TL;DR: A distributed mechanism for controlling delay jitter in a packet-switching network that makes the distribution of buffer space requirements more uniform over a channel's route, and reduces by a non-negligible amount the total buffer space needed by a channel.

06 Feb 1992TL;DR: In this paper, a packet rate control method for a packet network (1l - 1n, 2l - 2nl) is provided, in which a declaration of parameters indicating the rate of fixed-length packets is made to a call control system by a subscriber terminal device prior to communication as to be associated with a logical channel number.
Abstract: There is provided a packet-rate control method for a packet network (1l - 1n, 2l - 2nl), in which a declaration of parameters indicating the rate of fixed-length packets is so made to a call control system (5) by a subscriber terminal device prior to communication as to be associated with a logical channel number (LC). The rate of packets inputted to the network is so measured (101) 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 (103) 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 (104, 107) on the input side of the network. When there appears a possibility of congestion in the network, the marked packets are discarded (113). As a result, it is possible to prevent violation packets and marked packets from affecting the quality of service using normal packets.
