Description

ABSTRACT:
In a shaping processing apparatus which receives ATM cells as reception ATM cells which contains normal ATM cells and tagging ATM cells, a scheduling unit calculates a transmission time of the reception ATM cell based on a transmission time of a previous ATM cell belonging to a same connection as the reception ATM cell and transmitted immediately before the reception ATM cell and a predetermined time interval. A cell identifying unit identifies a connection number and cell priority of the reception ATM cell. The normal ATM cell has a higher cell priority than the tagging ATM cell. A mapping unit maps the reception ATM cell into a managing table based on the transmission time of the reception ATM cell to store the connection number and cell priority of the reception ATM cell in a storage area of the managing table. The managing table is associated with transmission times. The mapping unit outputs an address corresponding to the storage area as the write address to a shaping processing buffer such that the reception ATM cell is stored in the shaping processing buffer.
