Embodiment Construction

[0025] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0026] This application is applied to SDN, and virtualization technology is superimposed in SDN. The SDN includes multiple VFEs and VCEs. Each VFE is virtualized on a host device with a virtual machine. VCE can be an independent physical device or a physical A virtual device on a device, wherein, in the SDN, a VFE corresponds to a switching device, and a VCE corresponds to a control device.

[0027] Each host device in the SDN can communicate directly through the established tunnel.

[0028] In specific implementation, each VCE can also have a backup VCE, and one VCE can be used as the main VCE of one host device, and at the same time as the backup VCE of another host device, and each backup VCE can synchronize the information st...

Abstract

The present invention provides a virtual machine migration method. The method comprises a step of issuing the forward flow table to a target IP address to a managed VFE according to a global port table and a matched target IP address if a corresponding target IP address is matched in a first neighbor relation table with the IP address in information is taken as a source IP address when a VCE receives the information of an uploaded new port due to VM migration, and a step of sending a migration success message to other VCEs such that the other VCEs updates the forward flow table in the managed VFE according to the information of the new port. Based on the same invention concept, the invention also provides a virtual machine migration device, the process flow of the control equipment in an SDN is simplified, and the waste of resources is avoided.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a virtual machine migration method and device. Background technique [0002] Overlay network refers to superimposing a virtualization technology model on a network architecture. Its general framework is to realize the bearer of the application on the network without large-scale modification of the basic network, and can be separated from other network services, and is based on the basic network technology based on the Internet Protocol (Internet Protocol, IP). The basic principle of Overlay is to enable virtual machines to communicate in the tunnel through a tunnel encapsulation technology. [0003] At present, the main Overlay technologies mainly include virtual extensible LAN (VirtualeXtensibleLocalAreaNetwork, VXLAN), network virtualization using generic routing encapsulation (NetworkVirtualizationusingGenericRoutingEncapsulation, NVGRE), and stateless transport protoc...
