摘要: 针对自适应系统在运行过程中的状态一致性问题,基于公共对象请求代理体系结构(CORBA)规范,提出一种总线消息型的自适应系统实现方法。该方法以构件组装模型为核心,利用总线对运行时的构件进行状态侦测及重配置操作,使用事务处理机制解决CORBA系统的状态一致性问题,使系统可在运行时修改自身行为。在Java/C++复合构件组装工具上的实现结果验证该方法的正确性,并表明其具备较好的稳定性和自适应能力。

Abstract: Aiming at the runtime state consistency of self-adaptive system and based on Common Object Request Broker Architecture(CORBA) standard, this paper proposes an implementation method of bus based self-adaptive system. The core aspect of the approach is a component assembly model with self-adaptive ability. Bus is used to monitor components’ status and do reconfiguration, message transaction scheme is introduced to ensure system state consistency. It makes the system reconfigure itself at runtime. A Java/C++ composite component assembly tool which is developed independently is used to evaluate this method, result shows that it is a stable and it has self-adaptive.
Key words:
