Wire-wireless hybrid networking method of cloud data center based on SDN control

Abstract

The invention discloses a wire-wireless hybrid networking method of a cloud data center based on SDC control, and belongs to the technical field of the cloud computing data center. The SDN controllerselects a wireless network card according to a server used by an application, and selects a used wireless access switch according to a wireless network card location and a resource residual conditionof the wireless access switch; the SDN controller distributes an IP address for the wireless network card according to the selected wireless access switch, and then establishes the network connectionfor the wireless network card as the underlay network for application communication; an application virtual network is used as an overlay network to migrate to the underlay network; after the use of awireless network temporarily constructed for the network debugging and management, the SDN controller dismantles the wireless network connection and recycles the related network resource. By using the method disclosed by the invention, the demands of other applications and management are satisfied by taking the wire network as the main and taking the wireless network as the assistance in the cloud data center, so that the cloud data center network is more flexible.

Description

technical field [0001] The invention relates to the technical field of cloud computing data centers, in particular to a wired and wireless hybrid networking method based on SDN control for cloud data centers. Background technique [0002] The following common problems are more likely to occur when using a wired network. Some applications cannot meet the application requirements if the wired network resources are insufficient when creating a new network; running applications may encounter network quality problems such as network congestion or failure. The network cannot be solved immediately, which affects the operation of the application; when it is necessary to obtain large operation and debugging data of the data center, the data transmission will lead to a decrease in the quality of the application network. [0003] With the maturity of wireless communication technology, it can be introduced into the data center as a supplement to the wired network, increasing the flexibi...
