| 摘 要： | 提出再现网络时延的方法，利用多线程技术对每一个接收到的数据报都建立独立的线程并进行一段真实的人工延时，或者根据网络不确定性时延对远程端控制队列的影响及采样信息处理器的数据使用规则，通过对数据报进行移动和数据覆盖再现网络时延，保证在进行远程控制算法的比较研究时，网络时延状况是一致的，在远程控制系统实验平台上进行实验，结果证明以上方法的可行性。

| Abstract: | Methods for the reappearance of net delays are introduced. Adopting multithread technique, a period of manual time delay takes effects on every received datagram, or according to the effects of Internet, uncertain time delays to control the queue in client and the rule of using data of the sampling information treated, the data transfer and dump are executed. The reappearance of net delays ensures the consistency of net delays when two telecontrol arithmetics are compared. Experiments are performed to testify the feasibility of these methods. |
