【摘要】 在现有工作流系统中,工作流引擎都采用了大内核结构,即内核同时完成调度功能和服务功能。但是在应用中,工作流引擎经常会被重构以适应需求,而大内核结构使得这种重构工作带来巨大成本。本文有针对性的提出了微内核-悬挂式组件结构,以改进现有工作流引擎,从而提高其灵活性。更多还原

【Abstract】 In all of the existing workflow systems,workflow engines are all be designed in Large-Kernel Architecture,that is,the kernel realizes both scheduling function and service function.However,in the practical application,workflow engines are often reconstructed to fit practical requirements.And the large-kernel architecture always brings us big cost.So this paper brings forward the Micro Kernel and Carried Module Architecture to improve the engine’s flexibility.更多还原
