ABSTRACT:
A cell disposal avoidance system is provided that can avoid disposal of the cells resided in the QoS buffer when a traffic of a specific QoS class in an ATM switch increases. The ATM switch includes a storage cell number monitor, a software data section813, and a software controller812. The storage cell number monitor monitors congestion of plural QoS buffers in the buffer3, 5. The software data section813stores a cell reading priority (WRR value) attached for each QoS buffer. The software controller812dynamically changes the WRR value when congestion of a QoS buffer is in a congestion state (at generation of cell disposal or buffer congestion alarm) and increases the WRR value of the QoS buffer in a cell disposal state. Cells are divided in a time division mode according to the weight of the WRR value and read in a round format from the QoS buffer. The ATM switch resets the WRR value to an initial value when the congestion of the QoS buffer ceases.
