| 摘 要： | 面向服务的体系结构(SOA)具有动态性与协同性,这使得传统的软件可靠性评估方法并不适于评估SOA应用的可靠性。该文提出了一种可靠性动态评估方法,其核心是由在线监测到的数据所驱动的服务组合可靠性模型。该模型通过自底向上的3个层次来分离目标系统的动态变化,即:服务可靠性的度量模型、服务池容错模型和基于Markov链的服务组合使用模型。经初步实例验证,该方法能够有效适应针对SOA应用进行全生命周期可靠性动态评估的需要。

| Abstract: | The dynamic,collaborative nature of the service oriented architecture(SOA) presents new challenges to traditional software reliability research and practice.This paper analyzes the main problems in evaluating SOA application reliability,with an approach to resolve these problems.The core method is a data-driven service composition reliability model supported by online monitoring.The model includes three levels: a reliability measurement model for single service at the bottom,a Markov chain based fault-toler... |
