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
List of SDN Controllers
Proprietary SDN Controllers● Brocade SDN Controller● Midokura● Juniper Contrail● HP VAN SDN Controller● Blue Planet● BigSwitch● Nuage VSC● VortiQa
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
