摘　　要：为解决存储卷IOPS控制过程中控制偏差大的问题,本文对令牌桶算法进行改进。首先利用客户端读写压力的动态持续性特点,然后引入调节参数N来调节添加令牌的过程。实验结果表明,改进算法可以显著降低存储卷IOPS控制偏差,控制偏差可低于原算法控制偏差的10%,提高了存储卷IOPS控制的鲁棒性和控制精度,进而提高存储系统的服务质量。To solve the problem of large control deviation in the IOPS control process of storage volumes,this paper improves the token bucket algorithm.Firstly,utilizing the dynamic persistence of client read and write pressure,and then introducing the adjustment parameter N to adjust the process of adding tokens.The experimental results show that the improved algorithm can significantly reduce the control deviation of storage volume IOPS,which can be lower than 10%of the original algorithm's control deviation.This improves the robustness and control accuracy of storage volume IOPS control,thereby improving the service quality of the storage system.
