Embodiment 1

[0046] see figure 2 , which is a schematic diagram of an embodiment of a virtual machine migration method provided in Embodiment 1 of the present invention, the method includes: the method is applied to an SDN network, and the SDN network includes an SDN controller, multiple servers, multiple virtual machines, and A plurality of switches, wherein the virtual machine is connected to the switch, and the plurality of switches are all connected to the SDN controller, and the method includes:

[0047] S201. The SDN controller issues an instruction to migrate the first virtual machine to the first server in the SDN network.

[0048] Wherein, the instruction includes address information of the second server where the first virtual machine is migrated, so that the first server migrates the physical resource information of the first virtual machine to the second server, and the first virtual machine is a virtual machine in the first server. In addition, the switches described in the ...

Embodiment 2

[0077] see Figure 7, is a schematic diagram of an embodiment of the SDN controller in Embodiment 2 of the present invention, the SDN controller includes a processor 701 and a transceiver 702;

[0078] The transceiver 702 is configured to issue an instruction for migrating the first virtual machine to the first server in the SDN network, where the instruction includes address information of the second server where the first virtual machine is migrated, so that the The first server migrates the physical resource information of the first virtual machine to the second server, and the first virtual machine is a virtual machine in the first server;

[0079] After the migration of the physical resource information of the first virtual machine to the second server is completed, the transceiver 702 is further configured to send a migration completion instruction to the first switch and the second switch, so that the first The switch locally deletes the flow entry of the first virtual...

Embodiment 3

[0087] An embodiment of the present invention provides a computer-readable storage medium, on which a computer program is stored, and when the program is executed by a processor, the method embodiment described in any one of the above virtual machine migration method embodiments is implemented.

[0088] Through the description of the above embodiments, those skilled in the art can clearly understand that the methods in the above embodiments can be implemented by means of software plus a necessary general-purpose hardware platform, and of course can also be implemented by hardware, but in many cases the former is better implementation. Based on such an understanding, the essence of the technical solution of the present invention or the part that contributes to the prior art can be embodied in the form of software products, and the computer software products are stored in a computer-readable storage medium (such as ROM / RAM, magnetic disk, optical disk), including several instruc...

Abstract

The invention discloses a virtual machine migration method, an SDN controller and a computer readable storage medium and belongs to the technical field of communication. The method comprises the following steps: the SDN controller sends an instruction for migrating a first virtual machine to a first server in an SDN network to enable the first server to migrate physical resource information of thefirst virtual machine to a second server; after the physical resource information of the first virtual machine is migrated to the second server, the SDN controller sends a migration completion instruction to a first switch and a second switch to enable the first switch to delete flow table items of the first virtual machine locally based on the instruction and enable the second switch to add theflow table items of the first virtual machine locally; and the SDN controller notifies equipment of the SDN network to update a network strategy. The method improves virtual machine migration networkconfiguration speed and indirectly improves virtual machine migration efficiency.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a virtual machine migration method, an SDN controller and a computer-readable storage medium. Background technique [0002] With the rise of cloud computing, more and more companies and individuals begin to use various services provided by cloud service providers, such as websites and website hosting services provided by Amazon Web Services (AWS). Without exception, these services are deployed on servers in cloud computing data centers. The cloud computing data center drives the development of the virtualization technology of the entire data center resource. For the purpose of saving management funds and maintenance costs, simplifying system maintenance and management, improving system load balancing, optimizing system power management, and taking into account user needs and data center management needs, the problem of virtual machine migration inevitably arises. ...
