ATM cell conversion circuit and ATM cell conversion method

摘要

Sending priority of plural stages is statically assigned according to a quality class and an output connection, and the sending priority is dynamically changed according to a state of sending request stacking every sending priority and a state of ATM cell conversion processing of a frame, and ATM cell conversion request means for issuing an ATM cell conversion request is provided every output route, and the cell conversion processing of the frame is selected and performed in the order of higher sending priority every time one cell conversion.
