计算机网络和网络控制系统的仿真研究

Simulation Study of Computer Network and Network Control System

我们生活的世界就是一个网络世界。复杂网络的规模较大,单靠网络实验进行研究不太现实。网络仿真技术目前已成为网络规划和设计的主要工具。它能够为网络规划和设计提供客观、可靠的定量依据,缩短网络建设周期,提高网络建设中决策的科学性,降低网络建设的投资风险。由于将网络引入控制系统,导致了新问题的出现:网络延迟、数据包丢失、数据包时序错乱等。传统的控制方法很难取得良好的控制效果。计算机网络和网络控制系统的仿真研究代表当代仿真网络化,成为热点问题之一。网络实时性、网络安全,也得到广泛关注。通过业界共同努力,一定要也一定能够让无拥塞的安全网络在我国问世。

World where we live is a network world. Complex networks are broad in scale of only network experiment is not practical to research. Network simulation technology has been main tool for planning and design of net-work. It can provide quantitative basis for network planning and design, shorten the time limit for network construction, raise scientific nature of policy decision and reduce risk of investment in network construction. Due to the introduction of network in control system, new problems appear ： such as network defering, data package let sliping, time sequence in disorder and so on. Traditional control method do not achieve success. Simulation study of network and network control system stands for networking of simulation, and has become a great demand. Real - time and safe of network, have obtained wide attention. Through hard work, safe and unobsteructed network will appear in China.
