摘要： 建立一个统一高效的服务模型,对于方便地集成异构的资源、提高网格应用系统的效率、便于用户使用网格资源等都起着十分重要的作用。文章介绍了开放网格服务体系结构(OGSA),提出了一个基于OGSA的服务模型,研究了模型中服务的发布、发现、调用与安全机制,并通过一个应用验证了模型的正确性,为网格服务的商业化提供了有力的支持。

Abstract: A uniform and efficient service model is very important to integrate conveniently heterogeneous grid resources, to improve theefficiency of grid applications, and to facilitate consumers to use grid resources. This paper introduces the open grid service architecture (OGSA),proposes a service model based on OGSA, investigates service publication, discovery, invocation and security mechanisms in the model, andvalidates the feasibility of the model by an application. Thus, the model provides powerful support for commercial grid applications.
