【摘要】 本文首先简要介绍了网络加速技术的诞生背景和CDN技术在提高宽带网络稳定性及服务质量方面的独特优势,然后具体研究分析了Web2.0对宽带网络的特殊需求并提出了基于ChinaCache CDN网络平台的解决方案,在此基础上重点研究了解决方案中软件产品的实现。在产品实现方面,本文重点结合作者在实习期间承担的通用上传管理子系统的工程实践,具体阐述如何采用软件工程思想和先进的软件开发技术进行软件产品的研发,如何将解决方案中的思想设计转化为一个可实际运行的产品。通用上传管理系统的分析和设计借鉴了迭代的软件工程思想,采用典型的面向对象的分析与设计技术,使用UML统一建模语言作为设计工具,应用开源框架并使用Java编程语言作为实现工具。文中通过对通用上传管理系统的需求分析、系统设计和系统实现的详细讨沦,形成了从分析到设计,再到代码实现的一个完整过程。文章最后,对本文主要完成的工作做了总结,并提出了研究的不足之处以及对今后研究的展望。本文注重理论与实践的结合,以理论指导实践。通过通用上传管理系统这个具体项目,完成了面向对象分析与设计及软件工程中一些关键技术在实际工作中的应用,加深了对这些技术的理解,培养了实际运用的技巧;同时也验证了这些技术在实践中的重要性和优越性,为今后更广泛的使用打下坚实的基础。通过实际软件产品研发过程的展示,阐明了基于CDN网络平台的解决方案从需求发现、系统架构到产品实现的过程,将解决方案中的网络架构、硬件选用及软件开发有机结合起来,为今后根据市场需求变化开发类似产品提供借鉴。更多还原

【Abstract】 This paper begins with the introduction of the network accelerating technique background and the technical advantages of CDN on improving the stability and quality of service for broadband networks. In the next part, we analyze the requirements of Web2.0 for broadband networks and then propose a solution for ChinaCache CDN based network platform. Finally, this work focuses on the study on software product implementation for the proposed solution.On the product implementation aspect, this work describes the method to apply software engineering and advanced software development to software product development based on the author’s experiences on common upload management sub-system project implementation.The analysis and design of common upload management systems is referred to the iterative software engineering. The object oriented analysis and design technique and unified modeling language (UML) is adopted for the design work, while open source framework and Java programming language is applied for the code implementation. Through the requirement analysis, we accomplish the design and implementation of the system, including the analysis, design, as well as code implementation. At last, we make a conclusion of the work that has done in this paper,bring forward some insufficiency in the research and envision of the research in the future.This paper combines theory and practice, in which practice is directed by the theory. Through this common upload management system project, this paper accomplish a series of object orient analysis and design as well as software engineering related techniques in practical works and applications. Through the software product research and development, this work introduces the solution for CDN network platform from the market requirements, system architecture, and product implementation. Moreover, this paper combines the network architecture and the hardware and software development in a reasonable mechanism, thus provide the reference for the changing market requirements in similar product development in the future.更多还原
