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

Virtual network management in OpenContrail


Let us now take a quick look at the process of creating a virtual network in OpenContrail and how it can be leveraged to provision a VM instance in OpenStack.

Creating virtual networks and VM instances

The steps given here will be important for understanding the service chaining concepts later in this chapter:

  1. The first step in creating a virtual network (VN) is to click on the icon for Configure in the OpenContrail navigation bar, as highlighted previously. The following screen should be displayed:

  2. Navigate to Networking | Networks and click on the + sign on the right-hand side of the screen. This will allow users to create a virtual network in OpenContrail.

  3. Enter a name for the VN and in the Subnets tab, click on the + sign to add a subnet for this network, as shown in the following screenshot:

  4. Once the network creation is successful, you will see the entry in the Networks table of OpenContrail, as shown in the following screenshot:

  5. We can log...
