Zhu Chang-hong · Journal of Chinese Computer Systems · 2013
Traffic measurement plays an important role in the areas of network management,network monitor,network planning and network scheduling.As the bandw idth grow th of Internet backbone abides by Moore Law,traffic sampling attracts more and more attention with the capability of acquiring network operation status at limited cost in real time.Based on the analysis of the current situation and deficiency of early traffic sampling algorithm,four new Internet traffic sampling technologies including elephant flow sampling,fair flow sampling,per-flow traffic measurement,and flow sampling oriented on network anomaly detection are surveyed thoroughly and the performance criterion of the four traffic sampling technologies are analyzed and proved in theory.The four research trends of the technology of Internet traffic sampling are foreseen in the end.
