[Abstract]:Network performance measurement is the core branch of network measurement field. It refers to the sum of a series of activities to test, verify and characterize the network performance index by using software and hardware tools in accordance with certain methods and techniques. It is a quantitative network performance index. Understanding and understanding the most basic and effective means of network behavior are widely used in many fields such as network modeling, network security, network management and optimization. This paper introduces the research status and progress in this field, and discusses the representative algorithms in bandwidth, packet loss and time delay measurement, starting with the basic idea, key technology and realization mechanism of the algorithm. In this paper, the influence of time inaccuracy of sudden background flow and spatial uncertainty of multi-hop network on bandwidth measurement is analyzed. The difference and relation between application of packet loss and detection of packet loss in packet loss measurement are discussed. The relationship between clock deviation and clock frequency difference in time delay measurement is discussed. Based on this, the challenges, development trends and future research directions of network performance measurement are discussed.
