基于中间件的动态重配置容错对象管理框架

A Dynamically Reconfigurable Fault-Tolerant Object Management Framework Based on Middleware

该文从容错QoS角度出发,为现有的基于中间件的容错对象管理框架增加自适应特性.首先把动态重配置定义成容错属性集(及其实现)、计算环境和资源变化描述、动态调整算法三者之间的互动关系,然后采用反射模型和发布/订阅模型建立了一个动态重配置管理框架,可以使系统在发现计算环境的变化、定制动态调整算法等多方面得到有力的支持,为系统有效实施动态重配置奠定了基础.

This paper tries to add a characteristic of self-adjusting, in the perspective of fault-tolerant QoS, for the Fault-Tolerant Object Management Framework. Then it defines dynamic reconfiguration as the relations of fault-tolerant properties （or their implementations）, descriptions of computing environment changes and dynamic adjusting algorithms. A Dynamic Reconfiguration Management Framework based on Reflection Model and Publish/Subscribe Model is presented, which gives applications strong support on discovering computing environment changes, dynamically customizing adjusting algorithms, and building a foundation for effective dynamic reconfiguration of applications.
