摘要
在理论分析和实验数据的基础上深入研究了基于包对技术的端到端路径容量测量中背景流量、数据包异常和时钟精度等因素对测量结果的影响,并利用模拟和测量的方法对包对的行为特征进行了定量分析.为了克服上述因素的影响,制定和实现了基于数据包四元组的优化策略,从而提高了路径容量测量结果的准确性和稳定性.
In the end-to-end path capacity measurement based on packet pair algorithm, there are some inference factors with effects on the measurement result, such as cross traffic, packet pathology and clock precision. The influence of these inference factors was discussed based on theoretical analysis and experiment data. To overcome these interferences, an optimization strategy based on four packets group concept was proposed and implemented. And the strategy increases the stability and the accuracy.
