The final version of this book contains 14 chapters which are related to emerging technology of software defined network and network function virtualization and areas and problems related to this field. The areas covered in this book relate to software defined network, Network function virtualization, controllers, protocols related to software defined network, software defined storage and wireless sensor network related to software defined network. This book will provide to be a vulnerable resource for undergraduate, graduate and post graduate doing research in the field of software defined network and network function virtualization. This book will also provide valuable to the researchers, developers of software defined networks and network function virtualization. Software-Defined Network (SDN) and Network Function Virtualization (NFV) are the latest technologies that fuel latest hype bubble in the networking industry and service provider environment. The book primary covers different features and aspects related to SDN and NFV including the practical knowledge that would paved up the way for the researchers for their work in this field. The book explains SDN with need for SDN with giving the practical knowledge taking implementation using real environment and simulation. The protocol used for SDN, OpenFlow is also discussed and explained with scalability and challenges related to OpenFlow. Open flow is a new protocol that used to decouple control plane from data plane. This book focusses on basics of OpenFlow protocol, its benefits and drawback. Book also focusses on controllers and their working which are used to
