KR970056455A - Method and device for controlling usage parameter in ATM switch - Google Patents

Abstract

The present invention relates to a method and apparatus for controlling usage parameters in an ATM exchange system. The invention relates to a usage parameter control apparatus in which each connection of a network shares one shift register. Comparing the number of cells with VCI = i stored in the register with the maximum value; When the number of cells with VCI = i is greater than the maximum type error, discarding the cells and inserting idle cells at the position of the current cell. As a result of comparison, the number of cells with VCI = i is less than the maximum allowable shift. Increasing the number of cells having VCI = i in the register by '1' and storing them in the shift register; Shifting the cell of VCI = i stored in the shift register N times so that the cell of VCI = 1 arrives at the output of the shift register; And reducing the number of cells having VCI = i in the shift register by 1, and then entering the cell having VCE = 1 arriving at the output of the shift register into the network. Therefore, not only can the average transfer rate and burst length be effectively controlled at the same time, but the entire connection can share one shift register, thereby reducing the load on the hardware, and by using the moving window, accurate usage parameter control is possible.
