Research on seamless resource discovery architecture based on ASP pattern of manufacturing grid

Abstract

Resource sharing on manufacturing grid(MG) consists of two parts: resource supply and resource application,which are connected by resource discovery.From the perspective of resource discovery,composite structure of resource discovery based on Application Service Provider(ASP) pattern of MG was proposed from two levels: first,on architecture of MG,one structure based on a general enterprise service center was proposed;second,on deployment architecture of ASP,architecture of multi-level and tree overlay network was proposed.They support with each other and provide support of seamless structure for resource discovery.This structure can realize lamination retrieval and multi-spot resource discovery in broad area and has features such as being enterprise-oriented and application-oriented and so on.Based on the architecture above,one parallel algorithm of resource discovery was designed whose performance was analyzed and compared with other algorithm.Finally,validity of this architecture is powerfully illustrated with a qualified example and realization about some parts of the architecture.
