This book explains how to use software-defined networking (SDN) technologies powered by the OpenFlow protocol to build networks that are easy to design, less expensive to build and operate, and more agile and customizable. Among the first books to systematically address the design aspects in SDN/OpenFlow, it presents the insights of expert contributors from around the world. Focused on OpenFlow engineering design and basic principles, it includes coverage of system architectures, language and programming issues, switches, multimedia support, and network operating systems.
