网络可靠性评估方法综述

网络可靠性评估随着网络技术的发展已成为一个广受关注的焦点问题,但网络的复杂性、动态性、多态性等特点使得传统可靠性评估方法很难适用于网络。就网络可靠性评估方法这一问题,对近10年的相关文献按连通可靠性、容量可靠性和性能可靠性3个方面进行了综述,并介绍了在这3类研究的基础上综合考虑网络业务支持能力的业务可靠性,总结了近10年网络可靠性评估方法的研究进展、存在的问题及未来的研究方向。

Survey on Network Reliability Evaluation Methods

With the development of the network technology, network reliability evaluation has been a hot research topic in these years. 13ut the traditional reliability evaluation methods arc hard to be applyied to network evaluation due to the complexity, dynamic and multi-state characteristics of a network. This paper divided the related literatures into three main types; connecting reliability, capacity reliability and performance reliability, and introduced the new application reliability which is based on the three types of reliability and considers the service support capacity of a network, then reviewed the research progress and the existing problems. Finally, the direction of future research was discussed.
