ABSTRACT:
A cell output contention control apparatus for a traffic shaper includes an arrival order ring buffer, a transmission order ring buffer, time slots, and determining units. The arrival order ring buffer includes non-storage cell slots in which cells or addresses thereof are stored in the order in which the cells arrive, and ideal transmission time slots correlated with the first slots and used to store the ideal transmission times of the cells. The transmission order ring buffer includes transmission cell slots in which cells to be transmitted at the respective actual transmission times sequentially assigned to the slots in advance or addresses of the cells are stored. Each time slot consists of a set of non-storage cell and ideal transmission time slots of the arrival order ring buffer and one of the transmission cell slots of the transmission order ring buffer such that a combination of the first and second slots is changed at least once within a 1-cell time. The determining units are arranged for the respective time slots to determine whether predetermined storage conditions including an ideal transmission time of a cell are satisfied, and transfer the cell stored in the non-storage cell slot to the transmission cell slot to store the cell therein when the storage conditions are satisfied.
