ABSTRACT:
An ATM switch system having a traffic control function to reduce cell loss probability and delay of cells communicated through a network to be equal to or less than acceptable values, respectively. To achieve traffic control function, the invention provides a circuit to observe the queue of cells in the buffer, and an overflow testing circuit for obtaining a distribution of the queue size according to observed values of the queue and testing to decide, according to the distribution, whether an event has occurred that the cell loss probability is shifted due to the input cells to a distribution related to a cell loss probability exceeding an upper-limit value of acceptable cell loss probability. The invention also provides an underflow testing circuit for testing, according to the distribution, whether an event has occurred that the cell loss probability is shifted to a distribution related to a cell loss probability less than a lower-limit value of acceptable cell loss probability such that the read delay and interval of input cells are altered according to outputs from the overflow and underflow testing circuits.
