1
00:00:06,760 --> 00:00:09,197
- Let's go over several
open source projects

2
00:00:09,197 --> 00:00:13,720
and components that are trying
to provide micro segmentation

3
00:00:13,720 --> 00:00:18,350
and also SDN capabilities, right?

4
00:00:18,350 --> 00:00:20,060
So starting with micro segmentation

5
00:00:20,060 --> 00:00:23,100
and other modern networking
benefits, you know

6
00:00:23,100 --> 00:00:26,780
examples of these open source
initiatives include things

7
00:00:26,780 --> 00:00:30,500
like neutron from open
stack, the open B switch

8
00:00:30,500 --> 00:00:34,500
or OvS the open virtual network or OVN

9
00:00:34,500 --> 00:00:39,380
the open daylight project or
ODL, and the open platform

10
00:00:39,380 --> 00:00:42,913
for network function,
visualization, or OPNFV.

11
00:00:44,220 --> 00:00:48,398
Now, Cisco also has a solution
called Contiv that also

12
00:00:48,398 --> 00:00:51,520
provides these type of capabilities.

13
00:00:51,520 --> 00:00:54,432
Now, as you really know, the
concept of SDN is very broad

14
00:00:54,432 --> 00:00:57,953
and every open source provider
and commercial vendors

15
00:00:57,953 --> 00:01:01,550
that actually takes a little
bit different direction.

16
00:01:01,550 --> 00:01:03,500
For example, the networking component

17
00:01:03,500 --> 00:01:06,690
of OpenStack is called Neutron

18
00:01:06,690 --> 00:01:11,524
and Neutron is designed to
provide networking as a service.

19
00:01:11,524 --> 00:01:13,730
And basically they can be used

20
00:01:13,730 --> 00:01:17,640
in private, public, and
hybrid cloud environments.

21
00:01:17,640 --> 00:01:20,590
Now, other open stack
components like Horizon

22
00:01:20,590 --> 00:01:24,160
which is actually the
web UI or Nova, which is

23
00:01:24,160 --> 00:01:28,960
the compute service, they
interact with neutron using a set

24
00:01:28,960 --> 00:01:33,073
of APIs to configure
the networking services.

25
00:01:33,073 --> 00:01:36,610
Neutron actually uses plugins
to deliver advanced networking

26
00:01:36,610 --> 00:01:40,073
capabilities and allow third
party vendors to integrate

27
00:01:40,073 --> 00:01:42,540
with the solution.

28
00:01:42,540 --> 00:01:44,750
Basically, neutron has two main components

29
00:01:44,750 --> 00:01:46,676
the neutron server and
a database that actually

30
00:01:46,676 --> 00:01:50,550
handles the persistent
storage and the plugins to

31
00:01:50,550 --> 00:01:52,720
provide additional services.

32
00:01:52,720 --> 00:01:55,490
Now, this is of course not
a class about Open Stack

33
00:01:55,490 --> 00:01:57,980
or Neutron, but you can
actually obtain more information

34
00:01:57,980 --> 00:02:01,040
about Neutron and Open Stack
at the link that I'm sharing

35
00:02:01,040 --> 00:02:01,873
on the screen.

36
00:02:02,720 --> 00:02:06,810
Now OVN was originally
created by the folks

37
00:02:06,810 --> 00:02:09,226
behind open V switch or OVS.

38
00:02:09,226 --> 00:02:11,610
And it was created for
the purpose of actually

39
00:02:11,610 --> 00:02:14,226
bringing an open source
solutions for virtual network

40
00:02:14,226 --> 00:02:16,909
environments and SDN environments.

41
00:02:16,909 --> 00:02:20,880
Now Open V Switch is actually
an open source implementation

42
00:02:20,880 --> 00:02:25,162
of a multilayer virtual
switch inside of a hypervisor.

43
00:02:25,162 --> 00:02:29,280
Now you can actually download
Open V Switch and, you know

44
00:02:29,280 --> 00:02:30,610
start playing with it

45
00:02:30,610 --> 00:02:33,906
and access the documentation
at openvswitch.org.

46
00:02:33,906 --> 00:02:38,906
Now another very popular open
source project that is focused

47
00:02:38,980 --> 00:02:42,580
on the enhancement of SDN
controllers to basically

48
00:02:42,580 --> 00:02:45,630
provide network services
across multiple vendors is

49
00:02:45,630 --> 00:02:49,740
called the open daylight project or ODL.

50
00:02:49,740 --> 00:02:52,987
Now for the exam, you only
need to have some high level

51
00:02:52,987 --> 00:02:56,250
familiarity with, you know,
these open source components

52
00:02:56,250 --> 00:02:59,119
and examples of them
and the concept of SDN.

53
00:02:59,119 --> 00:03:01,770
But if you actually want
to find more information

54
00:03:01,770 --> 00:03:05,900
about open daylight and you
know, of course, you know

55
00:03:05,900 --> 00:03:09,260
the underlying technologies,
you can go to open daylight.org

56
00:03:09,260 --> 00:03:10,640
as I'm showing on the screen.

57
00:03:10,640 --> 00:03:13,418
And also Cisco has several tutorials

58
00:03:13,418 --> 00:03:17,351
and additional information
about open daylight indefinite

59
00:03:17,351 --> 00:03:20,510
and you can actually
obtain more information

60
00:03:20,510 --> 00:03:23,623
at the link that I'm showing in my screen.
