SDN, NFV and OpenDaylight 2 Open, Programmable APIs Virtualization and Abstraction Layer New Revenue Lower Cost SDN NFV Orchestration, Automation and MANO Service Agility
Why SDN? New architecture with separate Control and Data planes Open Programmable Networks and APIsNew business models and revenue opportunitiesEfficiency in both capital and operational expensesSoftware-Defined Network (SDN) Platform APIs Open protocols with enablement for proprietary extensions Physical Network Physical Network Enterprise apps Security, load balancing, etc. services Focus Area for OpenDaylight
SDN Architecture Characteristics Directly programmable Agile Centrally managedProgrammatically configureOpen standards-based and vendor-neutral
SDN Overview
What is OpenDaylight? Open source project Modular, pluggable, and flexible controller at its coreImplemented strictly in softwareContained within its own Java Virtual Machine (JVM)Deployable on any hardware and OS that supports Java
Who is in OpenDaylight Project? Continuous Growth to 41 Members
Who makes products based on Open Daylight?

Is Opendaylight the only Open Source SDN Controller Available?
OpenDaylight Tools and Paradigms Java interfaces for event listening, specifications and forming patterns Maven - Build and dependency managementOSGi - Backend container framework that allows dynamically loading bundlesKaraf - OSGi based runtime
What is an Application Programming Interface (API)? set of rules ('code') and specifications that software programs can follow to communicate with each other.
What is a Representational State Transfer (REST) API? A REST API is an API in a specific architectural style originally communicated by Roy Fielding in his doctoral dissertationhttp://www.ics.uci.edu/~fielding/pubs/dissertation/rest_arch_style.htm
What defines a ‘RESTful’ API? Six constraints Start with Null Style Client-ServerStateless (Server)CacheUniform InterfaceLayered System
What distinguishes REST? Emphasis on uniform interface between componentsFour constraintsidentification of resourcesmanipulation of resources through representationsself-descriptive messageshypermedia as the engine of application state.
Why a ‘RESTful’ API Principle of generality Simplifies overall system architecture Visibility of interactions improved

What is Karaf? Small OSGi based runtime Lightweight container various components and applications can be deployed
What is OSGi (Open Service Gateway Initiative )? Java framework for developing and deploying modular software programs and librariesTwo componentsSpecification for modular components called bundlesJava Virtual Machine (JVM)-level service registry
What are the drawbacks of REST? Uniform interface degrades efficiencyinformation transferred in a standardized form rather than form specific to an application's needs
