VIRTUAL PATH SHAPING DEVICE

摘要

PURPOSE:To transfer constant speed service (CBR) traffic by utilizing the free band of variable speed service (VBR) traffic and to shorten output standby time in the virtual path (VP) shaping device of the cell of the virtual channel (VC) of the CBR by turning the VC of the VBR and the VC of the CBR to the same VP and performing shaping. CONSTITUTION:When the value of a VP output timer 54 becomes equal to or more than the minimum cell interval of the VP stored in a memory 52 and the value of a VBR output timer 44 is less than the minimum cell interval of the VP stored in the memory 52, control is performed so as to output the cell of the CBR. As a result, by preferentially outputting the cell of the VBR and securing the band of the cell of the CBR, the cell of the VBR and the cell of the CBR are multiplexed on the same VP and outputted and delay time due to the standby time of the cell of the CBR is shorten.
