[0038] The technical solutions of the present invention will be further described in detail below through the accompanying drawings and embodiments.
[0039] See figure 2 As shown in the schematic diagram of the cloud data center structure, the cloud management server, that is, the network virtualization component of the cloud management system (Could Management System, CMS), Neutron uses SDN as the back end of the network function, and the control logic is separately deployed on the SDN. For example, SDN can use the virtual network application Virtual Network App as the control logic to divide the physical network into multiple virtual networks for different tenants to use. The virtualized network can easily implement tenant network expansion and virtual machine migration. figure 2 In the data center, the network of the data center is divided into two subnets (domains), respectively corresponding to two bottom-level controllers, and also includes an upper-level controller.
