This is an introductory SDN and OpenFlow course explaining different visions of what SDN actually is. The course also shows you real world implementations of SDN in very large networks as well as highly secure networks.
You will also learn about how OpenFlow separates the control and data planes of networking devices.
You will then see a practical demonstration of an application communicating with an SDN controller and Open vSwitch devices.
See the full SDN architecture as part of the demonstrations:
- SDN Applications
- SDN Controller
- OpenFlow switches
See how hosts can be blocked using OpenFlow rules.

|Section 1: Welcome|
Welcome to the course.
In this video, David briefly explains the Introduction to Software Defined Network (SDN) and OpenFlow course.
|Section 2: Introductory Course: What is SDN?|
What do the inventors say it is? (00:47)
This video discusses Martin Casado's definition of SDN. Do the inventors of SDN actually know what SDN is?
Open SDN, SDN via overlays, White box SDN (03:10)
This video discusses visions of SDN into different compartments and implementations of SDN controllers:
- Open SDN using OpenFlow
- SDN via Overlays (NSX, Nuage Networks)
- White box SDN (Pica8, Cumulus Linux)
- Open Compute Project (Facebook)
SDN via APIs, Cisco ACI (ASICs), OpenStack, NFV (04:32)
This video discusses SDN via APIs, SDN via ASICs and NFV:
- What is SDN via APIs? (SNMP, NETCONF, OVSDB)
- What is OpFlex / ACI?
- What is OpenStack?
- What is NFV?
|Section 3: Is this actually real?|
Real World SDN -Google (03:27)
This video discusses Google's implementation of OpenFlow & SDN.
Real Word- Microsoft (00:22)
This video discusses a Microsoft implementation of SDN.
Real World SDN - NSA (02:07)
This video discusses how the NSA implements OpenFlow and SDN.
Real World SDN (00:53)
This video discusses Facebook's two Open Source hardware switches.
Linux on switches (00:35)
Why use proprietary switch operating systems? Why not run Linux on a switch? Well, you can.
Which SDN Controller should you use? The SDXCentral report gives you some ideas.
|Section 4: Open SDN and OpenFlow|
What is a control and dataplane?
RIBs and FIBs and separated control planes.
I have developed a new routing protocol... David's Dodgy Routing Protocol (DDRP). Will you use it?
Servers have been virtualised. Why haven't switches and routers?
Network Abstraction and virtualization
What are the three parts to the SDN architecture?
- Application layer
- Control layer
- Infrastructure layer
SDN Architecture (continued)
What is the Northbound API, Southbound API and East & West?
|Section 5: Demo-Applications & Controller & Infrastructure|
What is Mininet? Where do I get it?
Demonstration of Mininet and an SDN Controller.
Mininet with 50x OpenFlow switches
SDN App Store, App install and Network flow update
REST API - SDN Application
