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

Using OVS as an SDN-capable virtual switch


OVS is a production quality multilayer virtual switch created back in 2009. It is the same as OpenDaylight; it is also provided by Linux Foundation.

Open vSwitch was created by a company called Nicira, which was later acquired by VMware and became a core part of the current VMware NSX network virtualization platform.

OVS quickly became the favorite virtual switch for virtual environments, and it is now playing a large part in other open source projects, such as OpenStack, oVirt, and Proxmox.

OVS is layer 2 switch and it supports different technologies and protocols, such as 802.1Q, BFD, NetFlow, sFlow, port mirroring, VLANs, LACP, VXLAN, GENEVE GRE Overlays, STP, and IPv6.

From a control and management perspective, Open vSwitch supports both OpenFlow and the OVSDB management protocol, which means it can operate both as a soft switch running within the hypervisor and also as the control stack for the switch silicon. You can leverage OVS on a bare metal...
