Stationarity Testing of Accumulated Ethernet Traffic

摘要

We investigate the stationarity property of the accumulatedEthernet traffic series. We applied several widely usedstationarity and unit root tests, such as Dickey-Fuller test and itsaugmented version, Phillips-Perron test, as well as the Kwiatkowski-Phillips-Schmidt-Shin test and some of its generalizations, to the assessmentof the stationarity of the traffic traces at the different timescales. The quantitative results in this research provide evidencethat when the time scale increases, the accumulated traffic series aremore stationary.
