Abstract：Network measurement technology is an important field in network research, and is of great meaning in both theory and practice. This paper introduces the concept, taxonomy from different points of view, and current research situations related to network measurement. It analyzes common measurement methods, tools and some hot points, addresses the main research organizations and network measurement architectures. Based on the research above, a Network Performance Measurement Infrastructure (NPMI) is presented. Finally, it gives future directions and development trend of network measurement technology.
