Data flow adaptive adjustment system and adjustment method in virtual machine hot migration procedure

Abstract

The invention discloses a data flow adaptive system and corresponding adjustment method in a virtual machine migration procedure, which aims to solve a problem of data packet dropout caused by neglect of processing of a data packet subsequently arriving in an original physical machine during ''shutdown-restart'' in the prior art. The system comprises a transmitting end for redirecting the data packet when the virtual machine shuts down, a receiving end for retransmitting the data packet after the virtual machine restarts and a migration mechanism for migrating the data packet between the transmitting end and the receiving end. According to the method provided by the invention, the virtual machine can still process the data packet arriving in the original physical machine after restarting in a new physical machine through sequential combination of the three parts, thereby implementing an effect that the data packet arriving in the virtual machine in the whole migration procedure is nearly lossless and providing a foundation for designing various virtual machine schemes of the upper layer.

Description

technical field [0001] The invention relates to the field of cloud environment deployment, in particular to a data flow adaptive adjustment system and a corresponding adjustment method in the process of virtual machine migration, which belongs to the modification of the migration mechanism. Background technique [0002] In recent years, cloud computing and cloud deployment have made continuous progress in technology, and on this basis, applications and research on various cloud platforms have been derived. Virtualization technology is the basic technology of the cloud platform. After long-term development, there are already many mature virtual machine products. In addition to improving the resource utilization of physical machines as much as possible, the scalability and deployment flexibility brought about by developing virtual machines as much as possible has become a research focus. [0003] Most virtual machine migration implementation plans ignore the processing of sub...
