摘要:
复杂网络由大量节点和连接边组成,用传统的可靠性评估方法难以评估,面向服务的架构越来越多地应用于软件开发中,但是针对 SOA 复杂网络系统可靠性评估目前没有一种完美的方法。 对此,文中分别从网络静态属性及动态仿真的角度进行分析,给出了一种适用的 SOA 复杂网络系统可靠性评估方法。 首先通过对 SOA 中的 Web 服务描述文件WSDL 及 SOA 业务流程描述文件 BPEL 进行解析,构建出复杂网络模型,用于后续提取静态属性及动态可靠性仿真;其次对可靠性模型中的静态信息进行度量及通过故障传播仿真实验模拟系统实际运行情况对复杂网络可靠性模型进行脆弱性分析,获取复杂网络系统中的关键节点;最后,基于复杂网络可靠性模型中各节点可靠度通过蒙特卡罗仿真实验获取系统可靠度。
Abstract:
A complex network is composed of a large number of nodes and connected edges,which is difficult to be evaluated by traditional reliability evaluation method. Service-oriented architecture is more and more used in software development,however,there is no perfect method for reliability evaluation of complex network systems based on SOA at present. Therefore,a reliability evaluation method for SOA complex network system is presented based on the analysis of network static attribute and dynamic simulation. Firstly,through the analysis of WSDL and BPEL of Web service description document in SOA,a complex network model is constructed for subsequent extraction of static attributes and dynamic reliability simulation. Secondly,by measuring the static information in the reliability model and simulating the actual operation of the system through the fault propagation simulation experiment,the vulnerability analysis of the reliability model of the complex network is carried out to obtain the key nodes in the complex network system. Finally,the system reliability is obtained by Monte Carlo simulation based on the reliability of each node in the complex network reliability model.
