Research of QoS model for component system in real-time embedded environments
实时嵌入式环境中面向构件系统的QoS模型研究

The introduction of component-based development into real-time embedded platforms is desirable to adapt themselves to the heterogeneity of embedded applications, and it is necessary to satisfy the requirement of software development efficiency. Due to the dynamic resource requesting of real-time embedded platforms and the overall administrative features of system resources, the adaptation mechanism in application level is not the final solution, furthermore the additional QoS managing policy plugged into the current component framework is requisite. Thus, a CCM component-oriented QoS model was proposed, which could adapt itself to the fluctuating component states proactively. At the same time, hierarchy QoS transformer in this QoS Model can simplify the configuration of service QoS parameters greatly.
