【摘要】：隨著互聯(lián)網(wǎng)的飛速發(fā)展,Web用戶交互方式逐步成為代替本地應用的主流用戶交互方式,并承載著日益增加的功能,決定了用戶對系統(tǒng)的第一印象以及后續(xù)的使用效率。Web系統(tǒng)的性能日益受到人們的重視,作為影響用戶體驗的一個重要因素進入人們的視野。以HTML5為首的一系列技術則為Web系統(tǒng)的體驗提升提供了大量便利的實現(xiàn)方式,而類似Chrome和Firefox這樣層出不窮的新式瀏覽器以及改頭換面的IE對HTML5的各種特性支持日漸增強,推動著Web交互方式的高速發(fā)展,也使得在Web端進行性能優(yōu)化成為可能。特別是其中的Canvas等圖形技術,使Web系統(tǒng)中的圖形呈現(xiàn)和交互更加豐富多彩。 本文中的云監(jiān)測平臺名為“TANC",TANC網(wǎng)絡測量系統(tǒng)是將云計算技術應用于分布式網(wǎng)絡性能監(jiān)測系統(tǒng),分為Web界面、探針設計、集中管理與數(shù)據(jù)分析三個部分,其中的Web界面采用基TStruts2架構的Web系統(tǒng)。 本文首先對云監(jiān)測平臺需要使用的各種技術及性能優(yōu)化的背景知識進行了調(diào)研和總結(jié),同時還匯總了拓撲圖布局的相關知識。然后對云監(jiān)測平臺中的用戶體驗和交互功能進行了需求分析和總體設計并按照功能模塊進行了詳細的劃分,從性能優(yōu)化、交互細節(jié)改進和拓撲圖改進三個方面詳細介紹了具體的實現(xiàn),第三部分中還重點介紹了有形節(jié)點拓撲布局算法(SNTLA)。最后,在實驗網(wǎng)絡中主要對性能優(yōu)化和拓撲圖改進兩個部分進行了測試,并對測試結(jié)果做出了分析。測試結(jié)果表明系統(tǒng)性能提升行之有效,拓撲圖自動布局算法使用正常,且具備良好的瀏覽器兼容性,用戶體驗得到很大的提升,符合本課題的要求。
[Abstract]:With the rapid development of the Internet, Web user interaction has gradually become the mainstream user interaction mode instead of local applications, and carries increasing functions. The performance of Web system has been paid more and more attention by people. As an important factor affecting user experience, Web system has been put into people's field of view. A range of technologies, led by HTML5, provide a number of convenient ways to enhance the experience of Web systems, while endless new browsers such as Chrome and Firefox, as well as revamped IE, increasingly support the various features of HTML5. The high-speed development of Web interaction makes it possible to optimize the performance on the Web side. Especially, the graphics technology such as Canvas makes the graphics presentation and interaction more colorful in the Web system. The cloud monitoring platform in this paper is called "TANC". TANC network measurement system applies cloud computing technology to distributed network performance monitoring system. It is divided into three parts: Web interface, probe design, centralized management and data analysis. The Web interface adopts the Web system based on TStruts2 architecture. In this paper, the background knowledge of various technologies and performance optimization needed to be used in cloud monitoring platform is investigated and summarized. At the same time, the knowledge of topology layout is also summarized. Then the user experience and interaction function in the cloud monitoring platform are analyzed and the overall design is carried out, and the function modules are divided in detail, and the performance is optimized from the point of view of performance optimization. The detailed implementation of interaction detail improvement and topology diagram improvement are introduced in detail. In the third part, the visible node topology layout algorithm (SNTLA). Is also introduced in detail. Finally, the performance optimization and topology diagram improvement are tested in the experimental network, and the test results are analyzed. The test results show that the performance of the system is improved effectively, the automatic topology layout algorithm is used normally, and has good browser compatibility, and the user experience has been greatly improved, in line with the requirements of the subject.
