Abstract
In the process of memory pre-copy, aiming at the characteristic which the dirty pages may be re-transmitted, dirty pages based on the probability prediction pre-copy mechanism is proposed, which aims to reduce the data transmission and total migration time. The mechanism uses temporal locality principle, on the pages before transmission, probability prediction for memory page, give priority to transmission of dirty pages prediction probability low memory pages, avoiding high dirty pages resend. Simulation results show that: the mechanism can reduce the amount of data transmission, reducing downtime and total migration time.
