ABSTRACT:
The invention provides a dynamic traffic shaping apparatus which allows dynamic shaping processing wherein the shaping cell rate is varied dynamically in response to a rate variation of a terminal acquired from a network. The dynamic traffic shaping apparatus includes a rate information processing section for predicting a sending rate of a transmission terminal in response to rate control information detected from a cell directed from a reception terminal side toward a transmission terminal side and successively storing the sending rate in an updating manner as sending rate information of an arrival cell for each virtual path and each virtual channel. The cell stored in a cell buffer for temporarily storing an arrival cell arriving from the transmission terminal side for each virtual path and each virtual channel is read out at an interval based on the sending rate information stored in the rate information processing section corresponding to the virtual path and the virtual channel and is sent out to the reception terminal side by a read control section.
