The Research On Distributed Aspect-Components Model And Collaboration Framework For DCAM

Under the background of distributed adaptive problem, this paper firstly emphatically introduces the kernel structure, distributed aspect-oriented programming implementation and platform framework of the current mainstream distributed aspectual middleware platforms, and analyzes the pros and cons of them. Meanwhile, the paper introduces the whole model, AOP kernel and service kernel of dual core aspectual middleware model, which is the research group pre-research.Secondly, this paper structures the platform architecture for DDCAM from the overall. The core realization mechanism of distributed aspect middleware-DCAM doesn't support component communication in distributed environment. The paper extends the calling mechanism of aspect core, and then proposes distributed aspect-components model and collaboration framework for DCAM, meanwhile, introduces the main implementation mechanism of distributed collaborative framework. Not only does the extended DDCAM keeps up supporting for POJO, but also it makes the platform have better scalability, fault tolerance and satisfies the requirements of On-Demand Computing better in distributed environment through the introduction of the distributed collaborative framework.Subsequently, the core implementation mechanism of DACCF is stated, such as extending the core of AOP and aspect container, introducing aspect mediator and asynchronous message transfer mechanism. Meanwhile, this paper gives concrete exposition of core algorithm for management mechanism of distributed aspect-components model and distributed aspects manager, and fulfills the DDCAM design ideas.Finally, this paper displays the running sample's screenshots of the prototype system, and illustrates its pros and cons. Furthermore, it analyses the price paid for extended the core of AOP and DACCF through experiments, and measures perform.
