Abstract

Embodiments of the invention provide a cross-data-center virtual machine migration method, a service control gateway and a cross-data-center virtual machine migration. The migration method comprises: a target service control gateway of a target data center receives virtual machine migration information sent by a source service control gateway of a source data center; the target service control gateway configures a response strategy, an internal data channel between an ingress router of the target data center and a target switch, and an external data channel between the target data center and a user on the target switch; the target service control gateway sends configuration success information to the source service control gateway; and the target service control gateway installs an virtual machine to be migrated on the target server and provides service for the user. According to the embodiments of the invention, the strategy of the target switch can be automatically installed, the external data channel from the user to the target data center can be automatically installed, and the internal data channel between the ingress router of the target data center and the target switch can be automatically installed, thereby achieving the automatic virtual machine migration across data centers.

Description

technical field

[0001] The invention relates to virtual machine migration technology, and in particular to a method, service control gateway and system for virtual machine migration across data centers. Background technique

[0002] As a data integration system, a data center is usually composed of components such as computing systems, storage systems, communication systems, network equipment, environmental control systems, and security systems. It is often used for computing and storage of core business at the company level, or company organization operations Computation and storage of data. With the continuous development of science and technology and the emergence of technologies such as cloud computing / distributed computing, computing power, storage, etc. have also become an information technology service that is provided to customers. These services can be provided to customers by using the network, information technology, security and other capabilities of the data ce...

Embodiment Construction

[0034] figure 1 It is a schematic flowchart of Embodiment 1 of the cross-data center virtual machine migration method of the present invention. Such as figure 1 As shown, the virtual machine migration method across data centers includes the following steps:

[0035] Step S101: A target service control gateway (Service Control Gateway, SCG) of a target data center receives a virtual machine migration message sent by a source service control gateway of a source data center.

[0036] Among them, the target service control gateway can perceive the internal topology information of the target data center through the control channel inside the target data center, and can configure the devices inside the target data center; at the same time, the target service control gateway also communicates with the external transmission network of the target data center communicate with the control plane of the target data center to implement the establishment of the transport network connection...
