摘要
针对计算机网络中多媒体数据业务传输存在时延的情况,设计了一种自校正比例微分流量控制器,并从理论上分析和证明了系统的稳定性和可行性。该算法实现简单,适合计算机控制系统实现,在多媒体网络中具有实际应用价值。仿真结果表明,该算法能够快速有效地调节业务分组发送速率和缓冲区队列,提高链路利用率,有效的克服了时延影响。
With regard to the impact of transfer delay on multimedia digital service in computer network, this paper proposes a flow control scheme, a self-adaptive proportional-plus-derivative flow controller, and analyzes the stability and feasibility. The method is easy to implement and has a practical application in multimedia networks. The simulation results show that this method can improve the service send-rate and queue in buffer, increase the link utilization, and overcome large delay effectively.
