随着我国网络技术和信息化的飞速发展,社会对网络的日益依赖,以及计算机网络用户的增加。为了确保计算机网络的正常运行,不被其它因素所干扰,因此,计算机网络可靠性及优化设计成为重要的网络技术之一。本文通过简要介绍计算机网络与计算机网络可靠性,在了解计算机网络可靠性优化的标准及模型后,提出影响计算机网络可靠性的原因及优化方式,并针对计算机网络可靠性及优化进行详细分析。 With the rapid development of network technology and informationization in our country, the society increasingly depends on the network and the increase of computer network users. In order to ensure the normal operation of the computer network, it is not interfered by other factors. Therefore, computer network reliability and optimal design become one of the important network technologies. This paper briefly introduces the reliability of computer network and computer network. After knowing the standards and models of computer network reliability optimization, this paper puts forward the reasons and optimization methods that affect the reliability of computer network, and analyzes the reliability and optimization of computer network in detail.
