【摘要】：互聯網環(huán)境的動態(tài)性和不確定性,使得在互聯網中部署的Web服務呈現出動態(tài)性、開放性、多樣性等特性,如何自主地管理與有效地整合海量、動態(tài)Web服務正成為一個巨大挑戰(zhàn)。針對這一挑戰(zhàn),本文基于軟件Agent技術和語義Web服務技術提出了一種自主化服務匯聚方法,該方法可以支持海量Web服務的高效管理并使得應用能夠更好地應對Web服務的動態(tài)特性。本文工作成果主要包括:1)基于服務自主化技術,提出了自主化服務的管理模型。自主化服務管理模型利用分布式的服務社區(qū)管理自主化服務,每個服務社區(qū)管理一類服務,這種管理架構避免傳統SOA架構的單點故障與性能瓶頸問題。2)提出了自主化服務的匯聚技術。在自主化服務管理模型的基礎上,我們利用軟件Agent技術和語義Web服務技術設計并提出了一種基于語義的自主化服務匯聚模型和相應的匯聚算法。該模型利用Agent的交互機制,使服務社區(qū)間可以以自組織的方式使的服務能夠按其功能自主地匯聚到各個社區(qū)中,實現Web服務的分類管理。3)設計并實現了自主化服務管理與匯聚平臺。我們基于JADE框架與Web服務監(jiān)控技術設計并實現了自主化服務管理與匯聚平臺。該平臺實現了服務社區(qū)的創(chuàng)建與管理功能,而服務社區(qū)能對注冊的Web服務的進行自主化封裝并實現自動匯聚。最后本文基于公共測試數據集展開了實驗并對實驗結果進行了分析,此外本文設計并實現了一個模擬實際應用場景的案例。實驗的結果以及案例運行的效果表明本文提出的自主化服務的管理與匯聚技術是可行有效的。
[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.
