Problems solved by technology

[0010] However, due to the above configuration, after virtual host 2 is migrated from physical server 1 to physical server 2, physical switch 2 does not allow external users to access virtual host 2 through port 2, so external users will not be able to access virtual host 2

Embodiment Construction

[0044] The core idea of ​​the present invention is: the network management device perceives the network migration event of the virtual host, and sends the configuration to the upstream physical switch of the physical server that the virtual host migrates into (for the convenience of description, the upstream physical switch of the physical server that the virtual host migrates into is hereinafter Similarly, the uplink physical switch of the physical server from which the virtual host is migrated out is referred to as the uplink physical switch for migration), and the access restriction of the virtual host on the uplink physical switch is updated. The network management device can also issue configurations to the migrated uplink physical switch of the virtual host, and update the access restrictions of the migrated uplink physical switch to the virtual host.

[0045] In order to clearly introduce the scheme of the present invention, it is introduced in turn below:

Abstract

The invention discloses a method and a device for virtual network configuration migration. In the invention, a network management device senses a network migration event of a virtual host, and issues a configuration to a migration uplink physical switch migrated by the virtual host, and updates the access restrictions of the migration uplink physical switch on the virtual host; the network management device also can issue a configuration to an outmigration uplink physical switch of the virtual host, and updates the access restrictions of the outmigration uplink physical switch on the virtual host; the physical switches can flexibly control the access of external users on the virtual host through issuing configurations to the physical switches; as additional protocols are not realized during the process, the realizability is good; meanwhile, the realization process is independent from a detailed physical network, and does not need special supports from the physical network; therefore, the compatibility is very good.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and equipment for virtual network configuration migration. Background technique [0002] 1.1 Virtual network [0003] As a hot technology, virtual network has received more and more attention and been widely used, for example, it is widely used in data center construction. [0004] A typical virtual network structure such as figure 1 As shown, a virtual network including multiple virtual hosts and virtual switches can be constructed on a physical server. Compared with traditional physical networks, virtual networks have obvious advantages, such as integrating hardware resources, balancing network loads, and reducing network costs. [0005] 1.2 Virtual network migration [0006] An important application of virtual network is virtual network migration: when a resource (including CPU, memory, disk, and network throughput, etc.) has a bottleneck during the operation of ...
