People always demand for information. People store the data in the data center but the data can be generated and used anywhere, including Web, mobile application, subsidiary, partner station or branch. Since data exists everywhere, network becomes the foundation platform for the Data Center.

Data center network virtualization refers to transforming the physical resource to the logically administrated resource to break the barrier between physical structures to make all resources transparently operate on various physical platforms, so as to automatically distribute the resource and optimize the network.

Support to the network virtualization requires the data center flexibly divide the network. It consists of two aspects, one of which is the flexible virtualization of a physical device to several logically independent devices; the other of which is the combination of several physical devices to a logical material object to serve the business.

Virtualization of a physical device to several logically independent devices is shown as below:

 


Virtualization of several physical devices to a logical device is shown below:

By the network virtualization solution, Rich Cloud Technology enables the user to realize the very convenient resource scheduling (e.g. terminal scheduling and forwarding table scheduling), resource sharing (power sharing and forwarding capability sharing) and strength the anti-fault capability (disperse the risk to several physical material objects); or even cooperate with the server to establish the virtual data center configured according to the demand.
