Software-Defined Networking (SDN) with OpenStack

By: Sreenivas Voruganti, Sriram Subramanian

Overview of this book

Networking is one the pillars of OpenStack and OpenStack Networking are designed to support programmability and Software-Defined Networks. OpenStack Networking has been evolving from simple APIs and functionality in Quantum to more complex capabilities in Neutron. Armed with the basic knowledge, this book will help the readers to explore popular SDN technologies, namely, OpenDaylight (ODL), OpenContrail, Open Network Operating System (ONOS) and Open Virtual Network (OVN). The first couple of chapters will provide an overview of OpenStack Networking and SDN in general. Thereafter a set of chapters are devoted to OpenDaylight (ODL), OpenContrail and their integration with OpenStack Networking. The book then introduces you to Open Network Operating System (ONOS) which is fast becoming a carrier grade SDN platform. We will conclude the book with overview of upcoming SDN projects within OpenStack namely OVN and Dragonflow. By the end of the book, the readers will be familiar with SDN technologies and know how they can be leveraged in an OpenStack based cloud.

Preface

Chapter 3. SDN Protocols

In the previous chapter, we outlined the challenges of traditional networks and showed how a SDN architecture with its distributed control plane and centralized management offers a superior solution. In this chapter, we will delve into the underlying components and protocols that enable the SDN-based architecture. We will introduce Open vSwitch (OVS), a popular virtual switch in SDN environments and leverage it to gain insights into SDN building blocks.

We will cover the following topics in this chapter:

  • How protocols with definition of standard API are the key driver for the SDN architecture and solutions.

  • Introduction to Open vSwitch

  • Data modeling language: YANG (RFC 6020), data model: YANG data models, Encoding formats: XML, JSON, and YAML

  • Protocols: OpenFlow, NETCONF, RESTCONF, OF-CONFIG, OVSDB, and their role in SDN eco-system

  • Learning the protocols using sample configurations of software that implement and tools supporting configuration, monitoring of the packet...
