Overview of this book

OpenFlow paves the way for an open, centrally programmable structure, thereby accelerating the effectiveness of Software-Defined Networking. Software-Defined Networking with OpenFlow, Second Edition takes you through the product cycle and gives you an in-depth description of the components and options that are available at each stage. The aim of this book is to help you implement OpenFlow concepts and improve Software-Defined Networking on your projects. You will begin by learning about building blocks and OpenFlow messages such as controller-to-switch and symmetric and asynchronous messages. Next, this book will take you through OpenFlow controllers and their existing implementations followed by network application development. Key topics include the basic environment setup, the Neutron and Floodlight OpenFlow controller, XORPlus OF13SoftSwitch, enterprise and affordable switches such as the Zodiac FX and HP2920. By the end of this book, you will be able to implement OpenFlow concepts and improve Software-Defined Networking in your projects.

Summary

Ryu

Ryu originates from a Japanese word meaning flow. It is a component-based, open source SDN framework fully written in Python that provides a precise software component and comprehensive API essential for the development of network applications for control and management.

Ryu supports various protocols for managing network devices, such as OpenFlow, Network Configuration Protocol (NETCONF), and the OpenFlow Management and Configuration Protocol (OF-Config), Open vSwitch Database (OVSDB) management protocol. It currently supports OpenFlow versions 1.0, 1.2, 1.3, 1.4, and 1.5 and Nicira extensions. NTT labs currently supports the Ryu controller, and it is also deployed across its various cloud data centers.
