Introduction to OpendaylightBeny RajaCloud System Engineer

About me

● Working in the Virtualization Technology for the past 7 years and presently with CD CloudEnablers Pvt Ltd, Chennai since 2014

● Currently focusing on NFV - SDN App analysis and integrations for Campus and Datacenter networks

● Active member of Openstack India Meetup group and presented a talk in the Chennai Meetup last year

● Having hands-on experience on public and private cloud deployments with various distributions

SDN Controller

● SDN Controller is an application in software-defined networking (SDN) that manages flow control to enable intelligent networking

● They are based on protocols, such as OpenFlow, that allow servers to tell switches where to send packets

List of SDN Controllers

Opensource SDN controllers● Opendaylight● OpenContrail● Floodlight● Ryu● FlowVisor● Beacon● vneio/sdnc● Cherry

What is Opendaylight

● OpenDaylight is a collaborative, open source project to advance software-Defined Networking

● It is hosted by The Linux Foundation● It is written in Java ● It runs on JVM, hence potentially it can run on any

operating system● It delivers a common platform for SDN across the industry● The goal of this project is to accelerate the adoption of

SDN

Opendaylight Consortium
