Raj Jain and Subharthi Paul, "Network Virtualization and Software Defined Networking for Cloud Computing - A Survey," IEEE Communications Managzine, Nov 2013, pp. 24-31.


Network virtualization is the key for the current and future success of cloud computing. In this paper, we explain key reasons for virtualization and briefly explain several of the networking technologies that have been recently developed or are being developed in various standards bodies. In particular, we explain Software Defined Networking which is the key to network programmability. We also illustrate SDN's applicability with our own research on OpenADN - application delivery in a multi-cloud environment.
