摘要
当前软件体系结构的研究主要集中于静态体系结构,这种体系结构不能在系统运行时更改。许多系统,尤其是长期运行或具有重要使命的系统,需要在运行时更新演化,这样的系统不能用静态体系结构来建模和分析。而动态体系结构由于其可以在系统运行时发生更改,可以用来解决这些问题。本文详细分析了动态体系结构的特性,提出了一种基于构件的可动态更新的体系结构模型,并以一个客户机/服务器系统动态更新实例来分析和验证该模型。
Existing software architecture research has focused on static architectures, where the system architecture can not change during system execution. And many systems, especially long running or mission critical systems, need update and evolve during execution, and thus cannot be accurately modeled and analyzed using static architectures. However, dynamic architectures, where the system architecture may change during execution, can overcome these problems. This paper described the features of dynamic architectures in details, and proposed a component_based and dynamically updatable architecture model, and made an analysis and validation of the model through a dynamic updating process of the client/ server system.
