A practical guide to building programmable networks using OpenDaylight
About This Book
- Learn and understand how SDN controllers operate and integrate with networks; this book's step-by-step tutorials will give you a strong foundation in SDN, NVF, and OpenDayLight.
- Learn how to map legacy Layer 2/3 networking technologies in the SDN world
- Add new services and capabilities to your infrastructure and quickly adopt SDN and NFV within your organization with OpenDayLight.
- Integrate and manage software-defined networks efficiently in your organization.
- Build innovative network applications with OpenDayLight and save time and resources.
Who This Book Is For
This book targets network engineers, network programmers and developers, administrators, and anyone with some level of networking experience who'd like to deploy OpenDayLight effectively. Familiarity with the day-to-day operations of computer networks is expected
What You Will Learn
- Transition from legacy networking to software-defined networking
- Learn how SDN controllers work and manage a network using southbound and northbound APIs
- Learn how to deploy the OpenDayLight SDN controller and integrate it with virtual switches
- Understand the basic design and operation of the OpenDaylight platform
- Build simple MD-SAL OpenDaylight applications
- Build applications on top of OpenDayLight to trigger network changes based on different events
- Integrate OpenStack with OpenDayLight to build a fully managed network
- Learn how to build a software-defined datacenter using NFV and service-chaining technologies
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.
Style and approach
This is a step-by-step tutorial aimed at getting you up-to-speed with OpenDayLight and ready to adopt it for your SDN (Software-Defined Networking) and NFV (Network Functions Virtualization) ecosystem.
