网络系统可靠性研究现状与展望

摘要

首先探讨了网络系统可靠性的发展历程、概念与特点,进而从度量参数、建模、分析、优化4个方面系统综述了网络系统可靠性的研究现状,最后对网络系统可靠性研究未来的发展进行了展望.%Along with the networking progress of human society, the network systems, on whicb we depend, are larger and larger, more and more complex. It leads to that the reliability problems are more and more serious. This survey firstly discusses the development history, concept and characteristies of network reliability, and then reviews the status of network reliahiity from the respects of measurement, modeling, analysis and optimization, respectively. Lastly. this sur vey presents the prospects of network reliability
