The main purpose of the present work is to estimate the Hurst parameter in real-time as a measure of network traffic self-similarity. There are many possible solutions for Hurst parameter estimation, but in this research the discrete wavelet transform approach has been used. The main reason is the possibility to calculate discrete wavelet transform in real-time for every input sample separately. There is no need to accumulate data and calculation can be made right away, which means that transformed data will be available faster for Hurst parameter estimation and processing load shall be distributed more evenly. The discrete wavelet transform provides other means for traffic as well, such as classification, anomaly detection, load prediction and so on. The Hurst parameter estimator algorithm has been proposed as well with algorithm diagram for software implementation. This algorithm has been implemented and its performance was tested and compared to regular discrete wavelet transform algorithm performance. The results show that the algorithm for estimating Hurst parameter is capable of performing estimation in real-time. |
