Switching path setting method for ATM switch

Abstract

Abstract PURPOSE:To easily perform the quality control for every service classification for various kinds of service within an ATM exchange. CONSTITUTION:When a line interface part 11 receives a cell from an input line, a QCC tag displaying the quality class (class 0 to 3) required by the service of the cell is added. A QCC class buffer 30 stores the cell by making the cell correspond to the quality class in accordance with the QCC tag. In each quality class, each prescribed reading band is assigned, the cell is independently read for every quality class from the QCC class buffer 30 in the reading band. The addition value of the reading band of each quality class is the band of the path of a switch. The cell read from the QCC class buffer 30 is multiplexed by a multiplexor 13 and the cell is outputted to a switch part 20.
