【摘要】：越來(lái)越多的Web服務(wù)部署和運(yùn)行在開放的互聯(lián)網(wǎng)環(huán)境之上,采用發(fā)散的方式進(jìn)行管理和控制,并為用戶提供多樣化、不同質(zhì)量要求的功能。為了滿足持續(xù)變化和不同形式的服務(wù)請(qǐng)求,互聯(lián)網(wǎng)環(huán)境下的Web服務(wù)需要具備一定程度的自主性,并需要對(duì)自身的態(tài)勢(shì)情況以及駐留環(huán)境進(jìn)行有效的監(jiān)視,從而根據(jù)服務(wù)請(qǐng)求以及態(tài)勢(shì)情況為用戶提供有效和高效的服務(wù)支持。本文基于我們所提出的自主服務(wù)軟件模型,研究了對(duì)自主服務(wù)進(jìn)行監(jiān)視的關(guān)鍵技術(shù)及其支撐軟件工具,取得了以下幾個(gè)方面的具體研究成果。首先,針對(duì)自主Web服務(wù)的特點(diǎn),提出了自主Web服務(wù)的態(tài)勢(shì)模型,對(duì)自主Web服務(wù)的動(dòng)態(tài)屬性做了詳細(xì)的描述。該模型將服務(wù)態(tài)勢(shì)分為服務(wù)QoS、服務(wù)業(yè)務(wù)狀態(tài)和服務(wù)上下文信息三種類型,并對(duì)每種類型給出了明確的定義和描述方法。其次,提出了自主Web服務(wù)態(tài)勢(shì)監(jiān)視和管理的關(guān)鍵技術(shù),主要包括態(tài)勢(shì)監(jiān)視實(shí)現(xiàn)模型、態(tài)勢(shì)適應(yīng)性監(jiān)視技術(shù)、態(tài)勢(shì)信息的存儲(chǔ)和查詢技術(shù)等,從而實(shí)現(xiàn)有效和高效的自主Web服務(wù)態(tài)勢(shì)監(jiān)視。在具體的技術(shù)實(shí)現(xiàn)上,我們利用Java擴(kuò)展管理技術(shù)和Java消息服務(wù)技術(shù)實(shí)現(xiàn)了對(duì)自主Web服務(wù)態(tài)勢(shì)信息的監(jiān)視和管理。第三,設(shè)計(jì)并實(shí)現(xiàn)了自主Web服務(wù)態(tài)勢(shì)監(jiān)視平臺(tái)以及一組自主Web服務(wù)的開發(fā)、部署和態(tài)勢(shì)管控工具集,它們支持從Web服務(wù)的自主化封裝、協(xié)同訪問(wèn)以及服務(wù)態(tài)勢(shì)信息的獲取和管理。最后,開展了針對(duì)水下不明物體探測(cè)應(yīng)用的案例分析和實(shí)現(xiàn),展示了本文研究成果的可行性和有效性。
[Abstract]:More and more Web services are deployed and run on the open Internet environment. They are managed and controlled in a divergent manner, and provide users with various functions with different quality requirements. In order to meet the continuous changes and different forms of service requests, Web services in the Internet environment need to have a certain degree of autonomy, and need to effectively monitor their own situation and resident environment. In order to provide effective and efficient service support for users according to service request and situation. Based on the model of autonomous service software proposed by us, this paper studies the key technologies and supporting software tools for monitoring autonomous services, and obtains some concrete research results in the following aspects. Firstly, according to the characteristics of autonomous Web services, the situation model of autonomous Web services is proposed, and the dynamic attributes of autonomous Web services are described in detail. The model divides service situation into three types: QoS, service state and service context information, and gives a clear definition and description method for each type. Secondly, the key technologies of independent Web service situation monitoring and management are put forward, including the realization model of situation monitoring, the technology of situational adaptive monitoring, the storage and query technology of situation information, etc. In order to achieve an effective and efficient independent Web service situation monitoring. In the specific implementation, we use Java extension management technology and Java message service technology to realize the monitoring and management of autonomous Web service situation information. Thirdly, the independent Web service situation monitoring platform and a set of autonomous Web services development, deployment and situation control tools are designed and implemented, which support the autonomic encapsulation of Web services. Collaborative access and service situation information acquisition and management. Finally, the case analysis and implementation of underwater unidentified object detection are carried out, and the feasibility and effectiveness of the research results are demonstrated.
