提出了一种基于信任抽样的P2P流量识别策略.在整个抽样识别的过程中,抽样比依据历史周期的P2P流量比例的估计量自动调整并动态变化.实验结果表明,基于对数变化的信任策略,能够在不增加抽样误差比率的同时有效降低系统的时间复杂度和资源消耗.
A P2P traffic identification strategy based on trust sampling was proposed in this paper.In the whole process of traffic identification,the trust sampling strategy will automatically adjust and dynamically change sampling ratio according to P2P traffic ratio estimator of historical cycle.The experiment results show that,trust strategy based on the logarithmic variation can effectively decrease the time complexity of the system and resource consumption on the condition of not increasing sampling error ratio.
