Network Virtualization provides an abstraction layer that decouples physical network devices from business services delivered over the network to create a more agile and efficient infrastructure.

Network Virtualization is the logical next step after storage and server virtualization. It allows multiple applications to run side-by-side over the same physical network. Each virtual network obeys business oriented policies while providing the security, availability and performance required for each service, from SAP and mail to VOIP and video.
Virtual networks optimize the manageability and control of physical networks that are shared between multiple applications. The result is a quickly deployable, more reliable service that takes advantage of all the capabilities of the underlying hardware.
