Network Virtualization

Network virtualization allows you to combine all of the resources available on a network by splitting up the available bandwidth into independent channels. These channels can then be assigned or reassigned to a particular device or server in real time. Any user or device that has access to the virtual network has access to any other resource on the network.

A virtual network can make the maintenance and administration of the network easier by allowing for centralized access to all the resources in the virtual network. For example, files, folders, storage media, and programs can be centrally managed from a single physical location. Physical devices can be easily added and made available to users of the network. Additional benefits to a virtual network include the following capabilities:

▲ Consolidation of many physical networks into one virtual network.

▲ Partitioning of a single physical network into many virtual networks.
