Abstract:

In order to have a better understanding of latest trends and technologies of network flow collection, and have a better research on network flow collection and other related researches, we summed up the methods and representative tools of network flow collection. By summarizing and analyzing the methods and tools, illuminate the key problems and core technologies of network flow collection so that provide the basis for further research of network data used by network measurement and management and reference of improving efficiency, veracity, practice ability, and applicability, and look forward to creating more efficient methods.

Key words: network flow, network data collection, methods, tools
