Rafael Pereira Esteves, Lisandro Zambenedetti Granville, Raouf Boutaba · IEEE Communications Magazine · 2013
Network virtualization is a feasible solution to tackle so-called Internet ossification by enabling the deployment of novel network architectures in a flexible and controlled way. With network virtualization, it is possible to have multiple virtual networks running simultaneously on top of a shared physical infrastructure. Network management with virtualization support, however, poses challenges that need to be addressed in order to fully achieve an effective and reliable networking environment. These challenges have motivated the investigation of novel management solutions in recent years. This article surveys some of the prominent solutions for network virtualization management and identifies research opportunities in the area.
