【摘要】：互联网环境的动态性和不确定性,使得在互联网中部署的Web服务呈现出动态性、开放性、多样性等特性,如何自主地管理与有效地整合海量、动态Web服务正成为一个巨大挑战。针对这一挑战,本文基于软件Agent技术和语义Web服务技术提出了一种自主化服务汇聚方法,该方法可以支持海量Web服务的高效管理并使得应用能够更好地应对Web服务的动态特性。本文工作成果主要包括:1)基于服务自主化技术,提出了自主化服务的管理模型。自主化服务管理模型利用分布式的服务社区管理自主化服务,每个服务社区管理一类服务,这种管理架构避免传统SOA架构的单点故障与性能瓶颈问题。2)提出了自主化服务的汇聚技术。在自主化服务管理模型的基础上,我们利用软件Agent技术和语义Web服务技术设计并提出了一种基于语义的自主化服务汇聚模型和相应的汇聚算法。该模型利用Agent的交互机制,使服务社区间可以以自组织的方式使的服务能够按其功能自主地汇聚到各个社区中,实现Web服务的分类管理。3)设计并实现了自主化服务管理与汇聚平台。我们基于JADE框架与Web服务监控技术设计并实现了自主化服务管理与汇聚平台。该平台实现了服务社区的创建与管理功能,而服务社区能对注册的Web服务的进行自主化封装并实现自动汇聚。最后本文基于公共测试数据集展开了实验并对实验结果进行了分析,此外本文设计并实现了一个模拟实际应用场景的案例。实验的结果以及案例运行的效果表明本文提出的自主化服务的管理与汇聚技术是可行有效的。
[Abstract]:Because of the dynamic and uncertainty of the Internet environment, the Web services deployed in the Internet show dynamic, open and diverse characteristics. How to manage and effectively integrate the mass of Web services has become a great challenge. In view of this challenge, this paper proposes an autonomic service aggregation method based on software Agent technology and semantic Web services technology, which can support the efficient management of massive Web services and enable applications to better cope with the dynamic characteristics of Web services. The main achievements of this paper are as follows: 1) based on the technology of autonomic service, the management model of autonomic service is proposed. The autonomic service management model uses distributed service communities to manage autonomic services, and each service community manages a class of services. This management architecture avoids single point failures and performance bottlenecks in traditional SOA architectures. 2) A convergence technique for autonomic services is proposed. On the basis of autonomic service management model, we design and propose a semantic autonomic service aggregation model and corresponding aggregation algorithm using software Agent technology and semantic Web services technology. The model makes use of the interaction mechanism of Agent to enable services that can be self-organized among service communities to converge autonomously into each community according to their functions. Implement the classified management of Web services. 3) Design and implement the autonomic service management and convergence platform. Based on JADE framework and Web service monitoring technology, we design and implement autonomic service management and convergence platform. The platform realizes the function of creating and managing the service community, and the service community can encapsulate the registered Web services autonomously and realize the automatic aggregation. Finally, the experiment is carried out based on the common test data set and the experimental results are analyzed. In addition, a case of simulating the practical application scenario is designed and implemented in this paper. The results of the experiment and the effect of the case show that the proposed autonomic service management and convergence technology is feasible and effective.
