1
00:00:01,370 --> 00:00:08,630
So what I'm going to try and do here is try and remove some of the hype and terms causing confusion

2
00:00:08,630 --> 00:00:15,380
and kind of group visions of software defined networking into different compartments.

3
00:00:15,590 --> 00:00:20,510
So the first vision and the original vision will define as open.

4
00:00:20,540 --> 00:00:26,690
SD And this is based on the original work at Stanford and uses the open flow protocol.

5
00:00:26,720 --> 00:00:31,280
The organization that's driving this today is the Open Networking Foundation.

6
00:00:31,490 --> 00:00:37,880
It defines software defined networking as the separation of the control plane and data plane.

7
00:00:37,940 --> 00:00:42,410
And later in this presentation, I'll explain what that actually means.

8
00:00:42,620 --> 00:00:50,360
Implementations of software defined networking controllers include open daylight or Odl on US NOx,

9
00:00:50,360 --> 00:00:56,420
Pox, Floodlight and others, including commercial controllers from the likes of HP and others.

10
00:00:56,990 --> 00:01:04,250
I'm creating multiple courses to explain each of these visions or examples of software defined networking.

11
00:01:04,459 --> 00:01:12,530
So have a look on the Genesis three website for more courses where I do deep dives into the details

12
00:01:12,530 --> 00:01:16,700
and nitty gritty of each of these visions of MSDN.

13
00:01:17,030 --> 00:01:22,520
The next vision is software defined networking via overlays, and the most famous example of this is

14
00:01:22,520 --> 00:01:25,250
probably NSX from VMware.

15
00:01:25,980 --> 00:01:30,510
As you can see in this video, Martin Casado works at VMware.

16
00:01:30,780 --> 00:01:36,630
His company, Nazara, was purchased by VMware a few years ago for over $1,000,000,000.

17
00:01:36,930 --> 00:01:43,140
And VMware now advocates a virtual network overlaid across a physical network.

18
00:01:43,500 --> 00:01:50,010
We have the concept of a underlay network, which are the physical network devices, and we have a virtual

19
00:01:50,010 --> 00:01:55,560
network that can automatically be deployed across the physical network.

20
00:01:55,800 --> 00:01:59,880
This uses protocols like VXLAN and NV Jari.

21
00:02:00,150 --> 00:02:07,500
Another example of this is Nuage Networks, which have a product for very high scale multi data center,

22
00:02:07,530 --> 00:02:10,530
multi hypervisor, virtual networks.

23
00:02:10,979 --> 00:02:17,740
A third vision or definition of software defined networking is what's called bright boxes or white boxes.

24
00:02:17,820 --> 00:02:26,370
So white box is examples of companies that are involved here include Picker eight and Cumulus Networks

25
00:02:26,670 --> 00:02:33,000
Y run proprietary operating systems tied to proprietary hardware.

26
00:02:33,300 --> 00:02:38,940
Why not run an operating system that can be installed on multiple vendor devices?

27
00:02:39,240 --> 00:02:42,660
So in this example, you could have a physical switch.

28
00:02:42,860 --> 00:02:44,070
And today is an example.

29
00:02:44,070 --> 00:02:49,080
You may want to run one operating system, but next week you may want to replace it with a different

30
00:02:49,080 --> 00:02:50,130
operating system.

31
00:02:50,400 --> 00:02:52,980
And that's what these vendors allow you to do.

32
00:02:53,010 --> 00:02:59,130
Don't buy proprietary hardware, proprietary operating systems and proprietary features, rather, by

33
00:02:59,130 --> 00:03:02,550
switches that are not tied to a specific vendor.

34
00:03:02,730 --> 00:03:08,340
Another example that kind of fits in this is the Facebook Open compute switches, such as six pack and

35
00:03:08,340 --> 00:03:09,030
wedge.
