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 legacy networking and SDN theory to the practical, real-world use of SDN in data centers and by cloud providers.The book will help you understand the features and use cases for SDN, NFV, and OpenDaylight. It also provides hands-on examples to build and use OpenDaylight in a test and lab environment on your computer.NFV uses virtualization concepts and techniques to create virtual network functions such as routers, firewalls, and load balancers using standard x86 servers. Used together, SDN and NFV can elevate the agility 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. You will also have mastered basic network programming over the SDN fabric.
Chapter 1, Introduction to SDN - Transformation from Legacy to SDN, explains SDN basics and covers SDN controllers and the position of OpenDaylight in the SDN ecosystem. It will help transform a traditional, legacy networking mind into an SDN mindset. It also covers a translation of how legacy network features, terms, protocols, and functions such as routing, switching, VLANs, and link aggregations are implemented in SDN.
Chapter 2, Overview of OpenDaylight, is about the OpenDaylight project and its components, history, and versions. OpenDaylight is a complex project based on multiple components that are tightly integrated. The aim is to make you familiar with the architecture of OpenDaylight in order to have a better understanding of how OpenDaylight works and the logic behind it.
Chapter 3, OpenDaylight Installation and Deployment, provides step-by-step installation instructions for OpenDaylight in a virtual environment. You will learn how to install it from scratch and in a Docker container.
Chapter 4, Building a Virtual SDN Test Lab with Virtual Switches, helps you build a virtual lab using mininet virtual-SDN-enabled switches.
Chapter 5, Basic Networking with OpenDaylight, is dedicated to performing basic network operations using OpenDaylight and SDN. You will learn basic networking operations and managing the fabric using OpenDaylight.
Chapter 6, Overview of OpenDaylight Applications, is about OpenDaylight applications. You will learn about OpenDaylight application programming using model-driven SAL (MD-SAL) in very basic steps.
Chapter 7, Building SDN Applications for OpenDaylight, helps you build an SDN application on top of OpenDaylight. We will go through SDN-based network access control (NAC) to understand how to hook up to OpenDaylight and take control of packet flow decision process.
Chapter 8, Network Function Virtualization NFV, gets you familiar with the role of OpenDaylight in an NFV ecosystem. You will learn about network function virtualization (NFV) basics, the OPNFV framework, and existing NFV projects. You will also learn about service chaining, which is one of the main use cases of SDN and OpenDaylight.
Chapter 9, Building a Software-Driven Data Center with OpenDaylight, summarizes and uses all the learning of this book by integrating it into a responsive software-driven data center use case. You will learn how to integrate and automate networking tasks from OpenStack to OpenDaylight, as well as understanding the role of network orchestration in a service-provider network by evolving OSS and BSS.
In order to keep up with the book, you will need to spend some time learning basic coding. Ensure that you have the following software installed:
- Oracle VirtualBox Or VMware workstation
- Ubuntu 16 server as base operating system for installation of OpenDaylight
- Mininet virtual appliance
- OpenDaylight Beryllium-SR4
- VTN coordinator
- PacketFence module for OpenDaylight
This book is for network professionals, network automation engineers, and developers who are working on software defined networking, network orchestration, and the cloud, in both service-provider and enterprise segments. This book tries to transform a legacy networking mindset to a software-defined networking one. Knowledge of networking is required.
In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning.
Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "We can include other contexts through the use of the include directive."
