The optimization of network protocol based on multi-scale DWT analysis

摘要

The optimizing strategy of network protocol is presented in this paper based on the multi-scale DWT analysis. Aiming at the characteristics of long range dependence and instability of the self-similar traffic flow, a forecasting model is established on FARIMA to carry on the analysis and prediction to the behavior properties of traffic flow with the estimation of Hurst parameter, then the abnormal trends are adopted in AQM algorithm to form the caution and response scheme, which can improve the effectiveness of dynamic traffic control and achieve the optimization to network protocols. Simulations show that this scheme can guarantee the implementation of congestion control, exhibiting favorable properties with stability and scalability.
