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.

Chapter 5.  Getting Started with OpenDaylight

In Chapter 2, Introduction to Software-Defined Networking, we showed how SDN solves the challenges faced by traditional networking when it is used in a cloud network infrastructure. We understood the need for a distributed control plane and centralized management in modern data center networking designs. It was highlighted that SDN technologies must provide abstractions, programmatic APIs, and multi-vendor support.

Let's now focus our attention on a specific SDN platform called OpenDaylight (ODL). OpenDaylight is an open source SDN platform developed by a community supported by key companies from the technology industry. The ODL project was launched in the year 2013 and its most recent release is named Beryllium. In a short span of time ODL has become the SDN and NFV platform of choice for the industry.

ODL addresses the key needs for SDN by supporting network abstractions, rich APIs, and multi-vendor support. Its architecture helps support large...
