DATA FLOW MIGRATION METHOD AND DEVICE

摘要

The present invention discloses a data flow migration method and device, and content includes: when it is determined to start migration between a source virtual machine and a target virtual machine, determining a silent time used for processing data flow migration; and receiving, within the silent time, a data flow packet sent by a switching node; and sending the data flow packet to the target virtual machine according to the data flow packet and a data flow migration policy. In this way, the silent time is used, a newly arrived data flow is redirected, and the newly arrived data flow is directly sent to the target virtual machine according to the data flow migration policy, which avoids migration of the newly arrived data flow. Therefore, data flows that arrive at the source virtual machine are on the decrease, an amount of memory data migrated between the source virtual machine and the target virtual machine is reduced, efficiency of data flow migration increases, and system migration performance is effectively improved.
