Abstract:For the inflexibility of NetFlow’s sampling probability, this paper proposed the algorithm based on packet rate adaptive for packet sampling. The algorithm measured the packet rate, employed the predefine measurement error, adaptively adjusted the sampling probability according to the change of packet rate and advanced to control the measurement error. Also conducted experiments based on real network traces. Results demonstrate that the proposed method can implement simplicity, controllability of measurement error with higher efficiency and without sacrificing accuracy, while memory consumption is lower compared with other methods.......
