Three color marker algorithm based on rate prediction
基于速率预测的三色标记算法

A new algorithm of data packet marker named three color marker algorithm based on rate prediction(Rate Prediction Marker,RPM) which fit for differentiated service was proposed.RPM algorithm is based on online traffic predictors algorithm.Network flows in DiffServ network were either divided by classifier or entering into marker makes flow prediction ahead of one period by RPM algorithm based on online traffic predictors algorithm.The packets were marked according to the results of prediction and the average weighed value of history flows data.When the sources may enter the recovery period of TCP congestion,the network available bandwidth was proportionally designated to serve congregation flows,and this raised the network bandwidth utilization rate.Simulation and experiment's results show that RPM algorithm has much higher performance when influencing aim rate and bandwidth's throughout compared with the existing algorithms,and get fairly fairness and bandwidth utilization rate.
