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 9.  Open Network Operating System (ONOS)

In Chapter 5, Getting Started with OpenDaylight, we showed how OpenDaylight (ODL) addresses the key needs for SDN by supporting network abstractions, rich APIs, and multi-vendor support. ODL acts as a controller for a distributed control plane, and also an on orchestrator for Virtual Network Functions (VNFs) and Service Function Chaining (SFC). Let us now focus our attention on a SDN platform called the Open Network Operating System (ONOS). While ODL primarily solves data center use cases, ONOS is architected for the carrier-grade networks requirements of performance, high availability, and scale, with well-defined abstractions.

In this chapter, we will start with an introduction to ONOS and its architecture, and we will then explore ONOS integration with Open vSwitch (OVS). We will conclude the chapter with a quick introduction to using ONOS in an OpenStack environment. We will cover the following topics in this chapter:
