【摘要】：在衡量IP网络的性能指标中，，丢包率(packet loss rate)是三种基准指标(丢包率，时延，吞吐量)之一。它是评价一个主机在网络整体中性能的必要测量项，其测量结果也是衡量网络所能提供的网络服务质量的重要参考依据。通过网络丢包率测量的结果，在掌握当前网络拓扑情况的前提下，也能为优化网络环境提供必要方法。因此，通过网络丢包率的测量对问题进行故障定位的研究有较高使用价值。 本论文就丢包率测量系统的实现方法进行了具体研究，并提出了一种基于贝叶斯优化算法来探测影响网络的问题点。论文首先对网络丢包率测量的相关理论与技术基础进行了总结和分析，为系统的实现打下了基础。然后对丢包率测量系统的通信协议进行了设计，使得测量系统的服务器和客户端能够交互通信信息。接着，对系统的实现方案进行了设计，包括服务器与客户端的通信连接实现，以及客户端与客户端之间的通信连接实现。并且通过丢包率测量结果给出了一个高效的故障探测算法。最后，对论文所实现的丢包率测量系统的运行模式进行了介绍，构造了多个不同参数情况下的测试样例对所实现的系统进行了测试与测量实验，并对实验结果进行了总结和分析。 论文完成了一个相对完整的网络丢包率测量系统，实验结果证明了所完成系统的功能正确性、有效性和健壮性，达到了论文所预设的工作目标。
[Abstract]:Among the performance indexes of IP networks, packet loss rate (packet loss rate) is one of the three benchmarks (packet loss rate, delay, throughput). It is a necessary measure to evaluate the performance of a host in the whole network, and the measurement result is also an important reference for evaluating the quality of network service provided by the network. Based on the results of the measurement of network packet loss rate, under the premise of mastering the current network topology, it can also provide a necessary method for optimizing the network environment. Therefore, the study of fault location through the measurement of network packet loss rate is of high practical value. In this paper, the implementation method of packet loss rate measurement system is studied in detail, and a Bayesian optimization algorithm is proposed to detect the problem points that affect the network. Firstly, the paper summarizes and analyzes the relevant theory and technical basis of network packet loss rate measurement, which lays a foundation for the realization of the system. Then, the communication protocol of the packet loss rate measurement system is designed, which makes the server and client of the measurement system can communicate with each other. Then, the implementation scheme of the system is designed, including the realization of the communication connection between the server and the client, and the realization of the communication connection between the client and the client. Furthermore, an efficient fault detection algorithm is presented by measuring the packet loss rate. Finally, the paper introduces the operation mode of the packet loss rate measurement system, and constructs several test samples with different parameters to test and measure the system. The experimental results are summarized and analyzed. A relatively complete network packet loss rate measurement system is completed in this paper. The experimental results show that the system is correct, effective and robust.
