摘要
在动态的网格计算环境中分布着大量不同类型的网格服务。快速、准确地进行网格服务发现是影响网格计算性能的关键因素。本文提出了基于本体和Agent的网格服务发现机制,它具有良好的扩展性和完备性。该模型采用A-gent代理技术进行服务搜索,不同的代理能够提供不同虚拟组织的本体知识库;利用本体论语义进行服务的匹配,从而实现智能化的服务发现。
Many different grid services are distributed in dynamic grid computing environments. The key factors affecting the performance of grid computing is to perform grid service discovery quickly and accurately. The paper proposes an ontology-based and agent-based grid service discovery mechanism which features good expansibility and integrity. The model a- dopts the agent technique to search services, and different agents provide different ontology knowledge bases of different virtual organizations. In addition, it uses the semantics of ontology to finish service matching, and achieves an intelligent service discovery.
