基于拦截器的容忍入侵中间件模型研究

Research of intrusion tolerance middleware model based on interceptor

在分析当今具有容忍入侵功能的中间件模型的基础上,提出了具有容忍入侵功能特性的中间件设计的基本要求,给出了一种基于CORBA/J2EE架构的具有容忍入侵特性的中间件架构,并对其中的关键技术设计作了功能性的描述。该架构利用拦截器技术实现了服务与管理模块的分离,该架构具有透明、可扩展性好、配置灵活等特点。

Basic requirements of design for middleware with the feature ofintrusion tolerance is proposed based on the analysis of current middleware model with intrusion tolerance function, and a middleware structure with the feature of intrusion tolerance based on the CORBA/J2EE is given, and the key technical function used in the structure is described. Interceptor is used for the separation of the service module and management module. The structure has feature of transparence, scalability, flexible configuration and so on.
