Service Mobility Management Method and System in Virtualization Environment

Abstract

The present invention relates to a service mobility management method and system in a virtualized environment. The method includes: when the FN needs to be migrated, the first virtual machine notifies the service management node of the virtual machine migration event through the virtual machine manager; the service management node notifies the second The virtual machine manager to which a virtual machine belongs sends a cache instruction; after the virtual machine migration process is completed, the second virtual machine notifies the service management node of the virtual machine migration completion event through the virtual machine manager; the service management node sends a notification to the first virtual machine The virtual machine manager to which it belongs issues a data transfer instruction, and the virtual machine manager to which the second virtual machine itself belongs transfers the received cached data to the second virtual machine. The present invention enables the virtual machine manager to cache the business data involved in the virtual machine during the migration process of the virtual machine, and forwards the cached data to the migrated virtual machine manager after the migration is completed, thereby maintaining the continuity of the business session without interruption.

Description

technical field [0001] The invention relates to the technical field of cloud computing virtualization, in particular to a service mobility management method and system in a virtualized environment. Background technique [0002] With the rise of the cloud computing boom, in order to improve the utilization of IT resources and reduce management and maintenance costs, a large number of applications will be deployed based on virtual resource pools. However, due to the dynamic nature of the underlying hardware, hardware resources can be upgraded, maintained, and regularly maintained, and virtual machines may migrate from hardware resources that are about to change to relatively stable resources, which leads to the following problems: [0003] 1. The application service needs to monitor the operation of the underlying basic resources in real time, and the application service directly schedules the underlying infrastructure resources, which increases the overhead of the application...

AI Technical Summary

Problems solved by technology

[0003] 1. The application service needs to monitor the operation of the underlying basic resources in real time, and the application service directly schedules the underlying infrastructure resources, which increases the overhead of the application service itself;

[0004] 2. Application services are tightly coupled with the underlying infrastructure. When there are multiple application services, resource conflicts are prone to occur;

[0005] 3. During the process of virtual machine migration, the IP address or link layer address may change, which will cause the communication between the service deployed on the virtual machine and other services to be interrupted;
