摘要

提出在基于概率预测的pre-copy算法的基础上

引入带宽自适应算法

当脏页率突然增大时

带宽自适应算法能够自动提高迭代传输带宽

缩短传输时间.实验结果表明

在脏页率较高和脏页率变化较大时

该策略能够明显缩短迭代传送时间和停机时间

提高迁移性能和业务服务质量.

Abstract

An Adaptive Bandwidth Algorithm is introduced in the pre-copy algorithm based on probability prediction. When dirty pages rate suddenly increases to a larger value

that algorithm could improve the transmission bandwidth to shorten transmission time. Experimental results show that the rate of dirty pages increase suddenly or is great

that strategy can improve the transmission bandwidth

shorten the total time of iterative transfer and downtime

so as to improve migration performance and quality service.
