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.But the traditional reliability evaluation methods are 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 relia-bility 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.
