Research of system fault-tolerance based on AOP
Guangyuan Li · Journal of Chongqing University of Arts and Sciences · 2009
Fault tolerance requirements should be satisfied transparently based on the provision of services of business logic for system fault tolerance.To realize fault tolerance transparently needs to address and manage the redundant resources,and realize failure detection and failure recovery.These fault-tolerant system requirements and business logic will be entangled together.Therefore,it has been the core issue of concern how to effectively weave business logic and fault-tolerant system needs together,make the system provide efficient and transparent fault tolerance to user with business logic services,to develop fault-tolerant system.The emergence of AOP provides an effective solution to weave business logic and fault-tolerant demands.In this article,based on the method of using AOP,varieties of business logic are defined as core concerns,while fault-tolerant needs are defined as different cross-cutting concerns,and then achieved as different aspects,at last business logics are wove together effectively by these aspects,so as to reach not only business logic,but also meets the demand for transparent fault-tolerance.
