Wired and wireless network virtualization [Guest Editorial]

Abstract

The Internet, which is a global heterogeneous network composed of diverse wireless mobile access, home broadband, and core IP/optical networks, is perhaps the critical element in future global ICT strategy. However, the way the current Internet is managed and the way it provides services cannot match the fast changing and more demanding requirements imposed by user-end applications. Network virtualization, coupled with an effective and efficient approach to managing virtualized resources, is a key solution to the problem.
