A buffer control system is a system for implementing both a priority control process and a shaping process of cells with a hardware configuration of a small size in a network routing fixed-length packets which are respectively composed of transfer data and control information added to the transfer data, and to which priority information is assigned, according to the control information. If a cell written to an empty area of a cell buffer 26 is a prioritized cell, and its expected output time is a time slot 6, an address where the cell is stored in the cell buffer 26 is arranged in a time slot 6 in a prioritized cell entry memory. When it reaches the time to read the cell stored in the time slot 6, address stored in the time slot 6 is written to an output list chain, and the cell is read from that address. The empty area of the buffer is managed using a free list chain. <IMAGE> |
