Abstract
In an ATM cell buffer managing system in an ATM node equipment, a buffer occupied amount of each individual logical channel of a buffer memory is measured by a buffer occupied amount counting portion, and a threshold value for each individual logical channel is dynamically derived on the basis of the measured buffer occupied amount for making judgement whether an input ATM cell can be received or not per each logical channel. By this, in the buffer memory, effective throughput of upper layer packet level can be improved.
