发布时间:2018-10-24 18:46
【摘要】:针对现有生存性模型缺乏实践指导意义及不能刻画Web应用特性的问题,对Web应用的特点进行讨论,尤其是对原子Web应用和组合Web应用的区别及特点进行探讨,重点考虑了如何对组合Web应用中各原子Web应用之间的调用关系进行分析和建模;同时通过将环境引入到生存性的分析中,分别构建了原子Web应用的生存性模型和基于马尔可夫过程模型的组合Web应用生存性模型。根据建立的Web应用生存性模型,提出一个在Web应用处于不利环境中时,部分或全部服务失效情况下的恢复方案。最后通过已建立的模型对一个案例进行了分析,给出了其恢复过程,在恢复过程中保证了较好的生存性。
[Abstract]:In view of the lack of practical significance of the existing survivability models and the inability to characterize the characteristics of Web applications, the characteristics of Web applications are discussed, especially the differences and characteristics between atomic Web applications and composite Web applications. This paper focuses on how to analyze and model the call relationship among the atomic Web applications in composite Web applications, and introduce the environment into the survivability analysis. The survivability model of atomic Web application and the combined Web application survivability model based on Markov process model are constructed respectively. Based on the established Web application survivability model, a recovery scheme is proposed under the condition of partial or total service failure when the Web application is in a disadvantageous environment. Finally, a case is analyzed by the established model, and the recovery process is given, which ensures a good survivability in the recovery process.
