The book covers the topics such that it would be beneficial for beginners, research scholars to find area of working, industry for getting practical exposure of implementation of network using software defined networks and network function virtualization. The book also contain data regarding automation in SDN which is hot topics for researchers finding the area of working in this field. The practical and simulation of SDN and NFV paved a way to learn the implementation of SDN and NFV network in real time and simulated environment. The discussion on security and quality of service also enable the reader to find the loopholes and area of research in the subsequent field of SDN. Integration of SDN with wireless sensor network is further enhance the content of book and paved a new research area in the field of SDN. Software defined storage is another area which make this book different from others. Thus, this book is said to provide a complete reference in the field of SDN and NFV which nearly covers all the topics related to SDN and NFV which make this book complete in itself.
