Abstract:

From the aspects of architecture extensibility, dependency relationship management,and aspect-oriented programming-supported granularity, this paper analyzes the architecture and the core of three typical middleware platforms. Then, for their common issues, this paper presents a new model on aspeetualmiddleware called dual core middleware model. This model has more advantages over extensibility, dependency relationship management and fine-granularit y AOP support than the current models. Meanwhile, it also includes the component mobile support, and satisfies the requirements of on-demand computing better. [
