This paper proposes a novel traffic shaping algorithm for jitter buffers. Jitter buffers are effective in reducing jitter and therefore constitute an important technique used to improve the quality of real-time communication. Traffic shaping regulates the interval between packets received at the destination. Although the well-known dynamic jitter buffer needs to identify the maximum one-way delay and current one-way delays in the network, it is not necessary for our proposed approach to supply this information. Our algorithm utilizes a feedback controller to adjust the queuing delay in the jitter buffer to avoid packet overrun and underrun. In addition, a constant packet-receiving interval is achieved by employing a low-pass filter. The validity of our proposed method is confirmed through experiments of position control over a network.
