Network functions virtualization, or NFV, is a once in a generation disruption that will completely transform how networks are built and operated. This mega-trend affects telecom operators, enterprises, governments and technology providers for uses ranging from next generation networks, 5G, smart cities, and IOT, to branch branch connectivity, and more. Open source has revamped how enterprises build out their IT systems. Now, open source software development promises to do the same for NFV. OPNFV is the open source project for integrated testing of the full, next-generation networking stack to enable accelerated NFV. This book covers all aspects of the OPNFV project, and this broad perspective will enable you to make the right decisions when it comes to using open source technologies for your NFV projects, and specifically how you take advantage of OPNFV. If you are an engineering, network operations or business leader who wants to understand how you can accelerate your NFV deployment, then this book is perfect for you. The book is also useful for technology providers trying to understand how to leverage the OPNFV framework and for individuals looking to expand their career into the growing NFV ecosystem.
