Learning OpenDaylight

By: Reza Toghraee

Overview of this book

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 SDN theory to the practical, real-world use of SDN in datacenters and by cloud providers. The book will help you understand the features and use cases for SDN, NFV, and OpenDaylight. NFV uses virtualization concepts and techniques to create virtual classes for node functions. Used together, SDN and NFV can elevate the standards 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 and integrate them with physical network switches. You will also have mastered basic network programming over the SDN fabric.

Preface

Introduction to network access control via OpenDaylight


In the previous chapter, you learned how OpenDaylight's MD-SAL works. You learned how to build a basic HelloWorld application based on OpenDaylight MD-SAL and build the model using YANG. We also reviewed how to use tools to process the YANG model file of our application in which to generate multiple Java source code files.

In this chapter, we will look at building a more practical SDN application for OpenDaylight. We are going to look at OpenFlow switches again and see how we can implement an Network Access Control (NAC) solution.

NAC is one of the well-known use cases for SDN. With SDN, network access control could become easier to deploy.

Note

Note to remember: OpenDaylight is an SDN controller; it is not a data plane component and does not process packets in terms of forwarding or alternation.
