| Abstract: | A shaping algorithm based on cell inter departure and token control is proposed. The algorithm can alter the peak rate, mean rate, maximum burst length and CDV of source traffic to expected values, and can guarantee the transparence of shaped traffic. The shaping delay is short as long as the traffic complies with the declared parameters. By simulation, the performance of the proposed shaping algorithm is evaluated. The implementation architecture of the shaper based on shared buffer, linked list and decreasing sequencer is given, and its operation is discussed. |
