摘要
为解决传统有线混合网络数据传输丢包率高、链路延迟长、利用率低的问题,提出一种有线混合网络数据传输拥塞优化控制方法。以单向延迟和可用带宽的检测结果为基础,采用马尔可夫模型预测有线混合网络传输的拥塞状态,将资源消耗和链路利用率作为优化控制的目标,在有线混合网络数据传输拥塞优化控制目标选择的路径符合要求下,根据其状态建立目标函数,完成优化控制。实验结果表明,该方法数据传输的丢包率小于4%,链路延时控制在0.05 s内,且其有线混合网络数据传输丢包率低,链路延迟短、利用率高。
In order to solve the problems of high packet loss rate,long link delay and low utilization in traditional wired hybrid network,a method of congestion optimization is proposed.Based on the detection results of one-way delay and available bandwidth,Markov model is used to predict the congestion status of wired hybrid network transmission,which takes resource consumption and link utilization as the target of optimization control.When the path of optimal control of the target meets the requirements,the congestion optimization control of data transmission of wired hybrid network is completed.The experimental results show that the packet loss rate of the proposed method is within 4%,the link delay is controlled within 0.05 s,and the packet loss rate is low,the link delay is short and the link utilization is high.
