Foreword:Network virtualization: the path to future Internet

摘要

The concept of virtualization is not new to the networking and computing communities. IBM initially pioneered the concept by supporting computing element (CE) virtualization on mainframe computers. A VMM (virtual machine monitor, such as IBM VM-CP) running on and controlling the bare-metal hardware supported multiple VMs with their own guest operating systems (OS) and applications. Similar virtualization technology (also known as OS/server/desktop virtualization) is now being supported on CEs based on the ubiquitous x86 architecture.
