Fault-tolerant model of web service composition based on aspect oriented programming

Abstract

To deal with Failure classification and code winding,a fault-tolerant model of web service composition based on aspect oriented programming is proposed.Firstly,fault reasons at all stage of Web services during execution are analyzed and classified,appropriate fault-tolerant strategies are presented,and web service composition model are built based on separation-of-concerns.Business function and quality of service are ensured,while function concerns and fault-tolerant concerns are separated.Finally,a case study of setup planning is presented to verify the feasibility of the method.
