【摘要】：随着互联网的飞速发展和云计算的迅速崛起，各种应用如雨后春笋般地出现。另外，移动互联网的发展导致了移动平台应用程序的装机数量暴增，例如微信，手机QQ等应用，这些软件在使用过程中大量的占用网络信令，给电信服务商带来了不小的压力。越来越多的应用也对网络的性能质量有了更高的需求。当前通信网络、计算机网络和有线电视网络的逐步融合，使得IP网络服务质量引起了人们的注意。而网络质量分析也是人们一直在研究的课题。进行网络质量分析，人们可以了解网络的实时性能，并进行快速的问题定位，及时地解决问题，，给用户带来更好的上网体验。以杭州华三通信公司的NQA(网络质量分析)开发项目为背景，提出了NQA的网络质量探测工具，主要功能是通过网络上常见的各种网络协议对当前网络质量进行测量分析，根据探测出来的结果，系统可以与其他模块进行联动，为整个系统的其他模块的路由选择提供参考。本文首先讨论了网络探测的基本原理，对探测协议作了简要的介绍，阐述了整个NQA的实现框架并引出了本课题需要解决的问题。然后详细介绍了NQA服务端的设计与实现方案，如系统功能和非功能模块的具体的运行设计。并重点讨论了设计时所遇到的问题及解决办法，包括如何处理大量并发探测，以及server存储配置的数据结构。最后给出了系统测试方案及结果，通过测试验证了该设计方案满足系统需求。应用该方案开发的相关产品已通过验收并开始逐步推向市场，一定会有非常广泛的应用前景。
[Abstract]:With the rapid development of the Internet and the rapid rise of cloud computing, a variety of applications have sprung up like bamboo shoots after a spring rain. In addition, the development of mobile Internet has led to a surge in the number of applications installed on mobile platforms, such as WeChat, Mobile QQ and other applications. These software occupy a large number of network signaling in the process of using, which brings a lot of pressure to telecom service providers. More and more applications also have higher requirements for the performance and quality of the network. At present, with the gradual integration of communication network, computer network and CATV network, the quality of service of IP network has attracted people's attention. And the network quality analysis is also the topic that people have been studying all the time. By analyzing the network quality, people can understand the real-time performance of the network, and carry on the fast problem localization, solve the problem in time, and bring the better Internet experience to the user. Based on the NQA (Network quality Analysis) development project of Hangzhou Huasan Communication Company, this paper puts forward the network quality detection tool of NQA, the main function of which is to measure and analyze the current network quality through various network protocols common on the network. According to the detected results, the system can be linked with other modules, which provides a reference for the routing of other modules of the whole system. In this paper, the basic principle of network detection is discussed, the detection protocol is briefly introduced, the implementation framework of the whole NQA is expounded, and the problems to be solved in this subject are introduced. Then the design and implementation of NQA server are introduced in detail, such as the specific operation design of system function and non-functional module. The problems encountered in the design and the solutions are discussed, including how to deal with a large number of concurrent detection and the data structure of server storage configuration. Finally, the test scheme and results of the system are given, and the design scheme is verified to meet the requirements of the system. The related products developed by this scheme have passed the acceptance and began to be put on the market step by step, and there will be a very wide range of application prospects.
