Abstract

The invention discloses a virtual machine live migration scene-oriented cloud network session connectivity guarantee method and system, and the system comprises a live migration module which is used for controlling the live migration from a source virtual machine to a target virtual machine based on a virtual machine live migration request; and the routing module is used for realizing forwarding and routing of the network data packet from the virtual switch corresponding to the source virtual machine to the virtual switch corresponding to the target virtual machine in the migration process. According to the method and the system, the session connectivity guarantee is realized by utilizing a live migration technology of the virtual machine carrying the session, and the cloud network service quality can be improved.

Description

technical field [0001] The present invention relates to the field of cloud network service quality assurance, in particular to a cloud network session connectivity assurance method and system for a virtual machine hot migration scenario. Background technique [0002] More than a decade ago, the global network entered the cloud network era. In recent years, cloud networks have provided services for all walks of life, including text, video, games, conferences, and public services. For cloud services, elastic, scalable, stable and highly reliable session connectivity is a matter of close concern to customers, and it is also an important indicator to measure the pros and cons of cloud vendors' products and services, all of which depend on the hot migration capability of the underlying virtual machines. The hot migration capability is also an important part of the hot migration of elastic computing services sold by major cloud service vendors. [0003] Existing cloud networks l...
