What is “OpenDaylight” ?

Controller + Southbound + Northbound + Apps

http://www.opendaylight.org/project/technical-overview

23


OpenDaylight Controller Overview

A highly available, modular, extensible, scalable,

and multi-protocol Controller infrastructure

The model driven Service Abstraction Layer for

abstractions to support multiple Southbound

protocols via Plugins.

A rich set of Northbound APIs via

RESTful web services for loosely coupled applications

OSGi services for co-located applications

The OSGi framework is used for the Modular and

extensible nature of the controller

Java-based Solution

24


OSGi & OpenDaylight

OSGi : Open Service Gateway Initiative

OSGi Alliance : IBM, Sun Microsystems, Errison … March 1999

OSGi Service Platform

OpenDayLight support OSGi framework and

bidirectional REST for the northbound API

The OSGi framework is running in the same address space for

applications

REST (web based) API do not run in the same address space

for applications

25


OSGi Architecture

Bundles – Extend OSGi components

Services – Connecting dynamic bundles to offer a publish-find-bind

model for plain old Java objects.

26

Life-Cycle - Install, start,

stop, update, uninstall bundles.

Modules - Bundle import and

export code

Security

Execution Environment

- methods and classes platform

OpenDaylight Architectural Framework

The Open Daylight Controller is a pure software and as a JVM.

OpenDaylight Network Virtualization

Platform Overview Named as OpenDaylight SDN Controller Platform

(OSCP)

A network application platform providing

Unified network intelligence

Enterprise-class scalability and high availability

Deploy a wide range of network applications, including data

center network virtualization.

OpenStack Quantum Plugin is provided via NB API

Java-based Solution

31


OpenDaylight Network Virtualization

Platform

1. SDN Controller Platform

2. OSCP Network Virtualization (ONV) application provides the tenant function

3. OSCP OpenStack Quantum Plugin programs the virtual network via ONV NB APIs

4. Enable the quantum feature from the CLI

5. Consistent Clustering

https://wiki.opendaylight.org/images/6/66/Oscp-proposal-image1.jpg


Network Virtualization Support

OpenDaylight SDN Controller Platform provides a plugin and

a corresponding agent to enable integration with Quantum.

Install the agent for restproxy plugin support

Enable the quantum feature from the CLI

OpenDaylight Network Virtualization (ONV) application is a

Network as a Service (network virtualization) application

currently runs on the OpenDaylight SDN Controller Platform.
