为了解决因业务流迅速增长而造成的网络拥塞现象,提出了一种新的业务流预测算法PSATP (Particle Swarm-ARIMA model based Traffic Prediction).该算法首先利用ARIMA模型和Kalman滤波建立预测方法,并且结合粒子群进行优化,使预测精度得以提高.同时,以实际数据进行仿真实验,深入研究了时延、丢包率与缓冲区、利用率之间的关系.相比于其他算法,仿真结果表明PSATP算法具有较好性能.
Abstract
In order to mitigate network congestion caused by the rapid growth of traffic
a novel traffic prediction algorithm PSATP (Particle Swarm-ARIMA model based Traffic Prediction) is proposed.In this algorithm
the prediction method is presented by ARIM A model and Kalman filter at first
and the prediction accuracy is improved with particle swarm optimization.Then
a simulation with actual data was conducted to study the relationship between delay
dropping rate buffer and utilization rate.The simulation results show that
