Fixed-length cell handling switching system and a method for controlling a read rate of a fixed-length cell

摘要

The invention relates to a fixed-length cell handling switching system and a method for controlling a read rate of a fixed-length cell. The fixed-length cell handling switching system has a quality class identifier relating unit for relating a quality class identifier according to a quality class of a cell, a quality controlling buffer unit including a managing unit, a buffer and a read rate information holding unit, and a call handling control unit including a virtual band setting unit for setting a virtual band of the buffer and a read rate setting control unit for setting and controlling a read rate, wherein a read rate for each quality class is dynamically changed, whereby a transmitting process is conducted according to a required quality class without affecting fixed-length cells of calls having different qualities on each other.
