通过对多掩码抽样算法抽样比率固定、无法自适应网络流量变化等的研究,提出了自适应的多掩码抽样算法。该算法能够在保证抽样随机性的前提下,实现抽样比率对网络流量变化的自适应改变,减轻对高速、大容量存储设备的依赖性,减少抽样过程对网络链路的影响。 Based on the research on multi-mask sampling algorithm with fixed sampling rate and inability to adapt to network traffic changes, an adaptive multi-mask sampling algorithm is proposed. The algorithm can adaptively change the sampling rate on the network traffic while ensuring the randomness of the sampling, reduce the dependence on the high-speed and high-capacity storage devices, and reduce the impact of the sampling process on the network link.
