【摘要】 分布式系统的可生存性研究已经成为当前安全领域关注的热点,如何提高系统的可生存性就成为了一个重要的研究内容,该文就从系统结构优化的角度研究了提高系统可生存性的方法。在文章中,以一个分布式系统作为案例,首先建立系统的仿真模型,然后通过3个实验证明了系统结构的变化能够影响系统的可生存性;最后提出利用Tabu搜索算法来优化系统的体系结构,以得到一个在限定条件下可生存性指标最好的系统结构。该文提出的方法是一种全新的思路,并具有一定的实用价值。更多还原

【Abstract】 The research on the survivability of distributed systems has become a hot topic in the fields of security.How to improve the system survivability is an important problem.This paper presents a method for improving survivability of the system from the view of the optimization of the system.The article takes a distributed system as an instance to show the process of the method.First,it establishes a simulation model,then illuminates that the alteration of the configuration of the system affects its survivability by three experiments,last,optimizes configuration of the system with Tabu Search Algorithm to find a kind of configuration which has the best survivability quantitative index under some limits.The idea of the method provided in this paper is a bran-new idea,and of a definite practicability.更多还原
