基于PID控制的网络传输拥塞自动疏导仿真

Automatic Congestion Mitigation Simulation of Network Transmission Based on PID Control

为合理分配网络算子的端口节点,防止信息数据不合理累积行为的出现,提出一种基于PID控制的网络传输拥塞自动疏导方法。通过连接PID控制器设备的方法,设定自适应网络的调节域,并以此为标准确定基础的调节比例,实现网络结构的PID控制调节操作。在此基础上,对所有传输节点进行静态分配处理,再根据网路疏导器件的配置结果,计算出准确的自动疏导重要度,完成基于PID控制网络传输拥塞自动疏导方法的建立。统一配置网络传输环境设计仿真结果表明,在理想状态下,交流变频处理、遗传处理、WDM处理三种方法对网络算子端口节点的分配合理性均不能达到预期效果,而随着基于PID控制网络传输拥塞自动疏导方法的应用,BAX指标出现明显的上升趋势,端口节点的分配合理性逐渐向预期数值靠近,信息数据不合理累积的问题得到有效解决。

In order to allocate the port nodes of network operators reasonably and prevent the unreasonable accumulation of information and data,this article puts forward an automatic dispersion method for network transmission congestion based on PID control.By connecting the PID controller,we set the regulatory domain of adaptive network.On this basis,we determined the basic adjusting proportion,and thus to adjust the PID control of network structure.After that,all transmission nodes were allocated statically.According to the configuration results of network mitigation devices,we calculated the importance of accurate automatic dispersion,so that the automatic dispersion method for network transmission congestion based on PID control was established.Finally,we configured the design of network transmission environment uniformly.Simulation results show that,in ideal conditions,when AC variable-frequency,genetic processing and WDM processing are used to allocate network operator port nodes,the rationality cannot be achieved.With the application of automatic congestion dispersion method based on PID control network transmission,BAX index shows an obvious rising trend.The rationality of port node allocation is gradually approaching the expected value.
