Abstract

The chaotic performance of small-time scale network traffic was covered by noise

which made the traffic unpredictable.This paper introduces the local projection to denosie network traffic;a chaotic and predictable traffic trend is obtained.As the network traffic series is long-period and time-varying

a new method named optimal training subset online fuzzy least squares support vector machines (OTSOF-LSSVM) is proposed.Samples temporal and distance nearest to prediction sample are chosen as optimal training subset

and the subset are fuzzified.On this basis

the prediction model is established by fuzzy LSSVM.The model update computational complexity is reduced by partitioned matrix calculation.The noise reduction and trend prediction on network traffic shows the proposed method can predict the trend quickly and exactly.
