【摘要】 随着新技术的不断涌现以及企业对于商业应用服务的需求 ,人们对ASP服务模型的探讨又活跃了起来。本文比较了网格环境下的P2P ,web服务等技术 ,指出了web服务技术能将各种分布的、异构的、由单一企业提供或者由各外部共享资源和应用服务提供商联合提供的动态服务整合起来的特性 ,并分析了ASP的演化将由传统的一对多模式转向web服务的趋势。最后结合具体的科研项目 ,提出了一种通用的ASP服务模型 ,还探讨了它在实际应用中的价值。更多还原

【Abstract】 With the appearances of new technology and business requirements,both practitioners and academics are becoming increasingly familiar with the term Application Service Provider(ASP).With the emergence of the Grid computing,Web service and Peer-to-Peer(P2P) computing is compared.Web service can integrate services across distributed,heterogeneous and dynamic communities formed from the disparate resources within a single enterprise and/or from external resource sharing and service provider relationships.ASPs’evolution paths can be from a pre-packaged one-to-many model to the interoperable Web service model.Finally,combined with a research project,an all-purpose ASP model is proposed.Its price in applications is also discussed.更多还原
