网络中影响实时业务质量问题节点的定位

An Approach to Locate Problem Node Influencing the Quality of Real-time Services in Internet

首先分析了现有的网段定位方法的不足,然后在分析实时业务流之间时延相关性的基础上提出了一种定位影响实时业务质量问题节点的方法,该文提出的定位方法部署容易且提高了定位粒度。仿真证实了这种定位方法是有效的。

This paper firstly analyzes the disadvantage of current approaches to locate network segment influencing quality of real-time services.Then based on the analysis of correlation of delay among real-time packets,we propose a new approach to locate problem node influencing the quality of real-time services in Internet.By contrast with current approaches,our approach is easy to implement and at the same time it has higher granularity.Simulation validates its theory basis and shows the validity of our approach.
