Research on distributed aspect-components model and collaboration framework for DCAM

The core realization mechanism of Distributed Aspect Middleware-DCAM doesn´t support component communication in distributed environment. In this paper we firstly extend the calling mechanism of aspect core. And then we propose a distributed aspect-components model and collaboration framework for DCAM. Not only does the extended DCAM keep up supporting POJO, but also it makes the platform have better scalability, fault tolerance capacity and satisfies the requirements of On-Demand Computing in distributed environment through the introduction of the distributed collaborative framework. Finally, we validate the distributed model of DCAM with an application and analyze its performance.
