【摘要】 随着IP网络规模和用户数目的不断扩大，业务种类日趋多样化，加之对服务质量、网络与信息安全的要求越来越高，给其运营、维护和管理提出更高的要求。同时，掌握IP网络的运行规律，对网络设备和协议的研究开发具有重要意义，为此促使了网络测量和业务性能的研究。本论文来源于国家自然科学基金重点项目：“基于网络探测的IP网络拓扑发现和性能分析的研究”，针对IP网络性能测量的一些关键技术和方法，设计并实现了端到端便携式IP网络性能测量仪SmsrtTestor2100，该测量仪采用了嵌入式Linux操作系统和基于ARM微处理器的硬件平台，实现了对IP网络性能的测量。论文重点研究了IP网络性能测量中数据包的捕获和分析以及网络瓶颈带宽测试技术，进行了编程实现，并且通过实际测试达到了设计要求，为进一步掌握网络真实的行为特征、网络协议和控制机制等提供可靠的理论依据，具有参考价值和应用前景。更多还原

【Abstract】 With the explosive development of the scale, the number of users, and the type of services of IP networks, more rigorous schemes to operation, administration and maintenance are required for building network infrastructure with high QoS and perfect information security. And it is important to master the behavior of IP network for research and development of network device and protocols. Thus, the research on network measurement and traffic performance is paid more attention.Research in the paper is supported by a NSFC (Natural Science Foundation of China) key project named as "IP network topology discovery and performance analysis based on network measurements", based on the key techniques and methods of IP network measurements, we design and realize the end-to-end portable IP network performance testor:SmortTertor2100, this testor adopts embedded OS Linux and ARM hardware platform, which successfully realizes the IP network performance measurements. This paper studies the two key techniques of IP network performance measurements—data packets capture and analysis as well as bottleneck bandwidth measurements, which are realized by programming, finally we meet the design demand by practically testing, moreover, it helps to master the behavior of IP network and study the networks protocol and control theory, this testor has reference value and application prospect.更多还原
