【Abstract】 A Distributed Network Measurement and Analysis Infrastructure (DNMAI) is presented and implemented partially, which is designed hierarchically and easy to extend. Compared with the existing infrastructures, DNMAI emphasizes the capability of customization on the scheme of measurement and analysis according to the user’s requirement, expands the analysis methods and application scenarios. Measurement can be implemented in a single point or many distributed points. The infrastructure model, functional modules, key technologies and implementation approaches are given. The measurement and analysis of end-to-end delay is shown as an example of the application of DNMAI.更多还原
