Preface

OpenDaylight is an open source, software-defined network controller based on standard protocols. It aims to accelerate the adoption of software-defined networking (SDN) and create a solid foundation for network functions virtualization (NFV).
SDN is a vast subject; many network engineers find it difficult to get started with using and operating different SDN platforms. This book will give you a practical bridge from legacy networking and SDN theory to the practical, real-world use of SDN in data centers and by cloud providers.
The book will help you understand the features and use cases for SDN, NFV, and OpenDaylight. It also provides hands-on examples to build and use OpenDaylight in a test and lab environment on your computer.
NFV uses virtualization concepts and techniques to create virtual network functions such as routers, firewalls, and load balancers using standard x86 servers. Used together, SDN and NFV can elevate the agility of your network architecture; generic hardware-saving costs and the advanced and abstracted software will give you the freedom to evolve your network in the future without having to invest more in costly equipment.
By the end of this book, you will have learned how to design and deploy OpenDaylight networks. You will also have mastered basic network programming over the SDN fabric.
