随着网络技术的迅速发展及其在生产制造领域的逐步渗透，基于网络的控制结构在工业生产中扮演着越来越重要的角色。然而，由于随机网络时延的存在，使得工业系统的网络化控制性能受到影响。为了减轻乃至避免这种影响，需要分析影响时延随机变化的因素。利用 OPNET 软件对控制网络进行模拟和仿真，对网络中时延、吞吐量等参数进行测量。通过改变网络的结构以及相关参数设置，使测量结果产生变化，通过对比测量结果找出与时延随机性相关的因素。

As the network technology is developing rapidly and infiltrating in the manufacturing filed,the control structure based on network is playing a more and more important role in the industrial practice. However,network control in the industrial practice is affected seriously by the random delay.In order to avoid the negative effect,the factors influencing the random delay needs to be analyzed.OPNET software was used to simulate the network and measure the characters includeing delay,throughput and others. By changing the structure of the network and the related parameters to uary the measurement results. After that,the factors associated with the randomness of delay are identified.
