Abstract
In a traffic shaping device which can control a cell sending rate with using a common circuit portion regardless of the number of cell buffers, cells 31 input to a cell input portion 32 are stored in corresponding ones of cell buffers 35.sub.1 .about.35.sub.N prepared for every one of traffics having different shaping rates. Cell buffer registers 41.sub.1 .about.41.sub.N are provided correspondingly to the cell buffers 35.sub.1 .about.35.sub.N and an output time from an output time notice counter 43 which is incremented every cell period is compared with values of cell output enabling time registers 48. One of the cell buffers which is enabled to output are permitted to output the cell stored therein if any through a cell output portion 37. Thereafter, the values of the cell output enabling time registers 48 are rewritten on the basis of contents of cell output interval registers 52. Regulation of priorities of the cell buffers is also performed by a priority registers 51.
