基于架构级容错的C2风格研究

Research of C2 architectural style based on fault tolerant at architectural level

为减少基于构件开发的软件系统中构件间的相互依赖,实现系统架构的动态演化,研究了一种被称为C2的软件体系结构风格。在C2风格的基础上,介绍并分析了通过对第三方构件进行保护包装,把这种现有的商用构件转换成一种理想化C2构件iC2C,以在架构级上达到系统容错的目的。通过研究iC2C的内部结构,提出了一种iC2C的实现架构。并结合实例把它应用在了具体的项目实践中,实验结果表明了该架构的可行性与可塑性。

To reduce interdepending between components in the software system that is developed on the basis of components, and implement the dynamic evolution of system architecture, a kind of architectural style of software system, known as C2, is studied.Based on the style, in order to achieve a fault-tolerant software system at the architectural level, turning the off-the-shelf components, by adding protective wrappers to them, into the idealized C2 components（iC2C） is introduced and analyzed.By studying the internal structure of iC2C, an architectural method of implementing iC2C is proposed.And a case study applying in the method demonstrate its feasibility and plasticity.
