Method and system for service mobility management in virtual environment

Abstract

The invention relates to a method and a system for service mobility management in a virtual environment. The method comprises the following steps: a first virtual machine informs a service management node of a virtual machine migration event through a virtual machine manager when an FN needs to be migrated; the service management node sends a caching instruction to the virtual machine manager to which the first virtual machine belongs; a second virtual machine informs the service management node of a virtual machine migration completion event through a virtual machine manager after the virtual machine migration process is completed; and the service management node sends a data transmission instruction to the virtual machine manager to which the first virtual machine belongs, and the virtual machine manager to which the second virtual machine belongs forwards received cached data to the second virtual machine. A virtual machine manager can cache service data related to a virtual machine during the migration process of the virtual machine, and forwards the cached data to a migrated virtual machine manager after migration is completed so as to enable service session to be continuous 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;
