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

What is YANG?


Published as RFC 6020, YANG is a data modeling language. Its function is similar to other data modeling languages, such as UML and XML; however, it has superior features, such as being human-readable and having support for configuration management.

It was created to be used for the definition of the data sent over the NETCONF protocol. It became popular after the success and rapid adoption of NETCONF.

Its configuration management capabilities are:

  • Development support and versioning
  • Supports submodules
  • Grouping and structured types
  • Supports the definition of operations (RPCs)
  • Reusable types
  • Hierarchical configuration for data models
  • Easy-to-learn representation, human-readable

About 25 years ago, SNMP was introduced as a protocol between networking management and control systems devices for exchanging configurations, operations, and statistical information. SNMP started using a data modeling language called Structure of Management Information (SMI). SMI evolved and became SMIv2, but people...
