Network Virtualization Platform
A network virtualization platform decouples the hardware plane from the software plane such that the host hardware plane can be administratively programmed to assign its resources to the software plane. This allows for the virtualization of CPU, memory, disk and most importantly network IO. Upon such virtualization of hardware resources, the platform can accommodate multiple virtual network applications such as firewalls, routers, Web filters, and intrusion prevention systems, all functioning much like standalone hardware appliances, but contained within a single hardware appliance. The key benefit to such technology is doing all of this while maintaining the network performance typically seen with that of standalone network appliances as well as enabling the ability to administratively or dynamically program resources at will.

Virtualization
In computing, virtualization (abbreviated v12n) is a series of technologies that allows dividing of physical computing resources into a series of virtual machines, operating systems, processes or containers. Virtualization began in the 1960s with IBM CP/CMS. The control program CP provided each user with a simulated stand-alone System/360 computer. In hardware virtualization, the '' host machine'' is the machine that is used by the virtualization and the ''guest machine'' is the virtual machine. The words ''host'' and ''guest'' are used to distinguish the software that runs on the physical machine from the software that runs on the virtual machine. The software or firmware that creates a virtual machine on the host hardware is called a '' hypervisor'' or ''virtual machine monitor''. Hardware virtualization is not the same as hardware emulation. Hardware-assisted virtualization facilitates building a virtual machine monitor and allows guest OSes to be run in isolation. Deskt ...
