Abstract: In the past few years, network virtualization (NV) has been growing steadily among other network communities. NV offers an alternative advancement of the future internet by utilizing protocols and architectures through shared physical infrastructure and control architectures in the network. The frequent usage of NV demands new requirements that focus on the control and management of the given network. The existing process that combines software network resources and network functionality and hardware has even made NV more important in the network field (e.g., virtual networks have become important resources in information technology). Virtual network has taken the importance of NV from the original hardware while server virtualization supersedes virtual machines from the original server hardware. Therefore, the aim of the current paper is to provide a review of related studies on virtualization and NV concepts as well as aims or objectives and the requirements of such NV. It provides a brief description of technology and outlines its current and future applications. Finally, the study discusses the difficulties in implementing this technology.
