Hello and welcome to examining app QOE or application quality of experience.

2
00:09.920 --> 00:16.770
This is basically the SD-WAN equivalent of QOS, but a lot more extra features

3
00:16.770 --> 00:18.000
added in,

4
00:18.000 --> 00:21.280
particularly focused at the WAN.

5
00:21.280 --> 00:26.730
So in this skill, we're going to start with an app QOE overview, where we're

6
00:26.730 --> 00:27.160
going to

7
00:27.160 --> 00:31.090
sort of jump in and just get our feet wet a little bit with some of the other

7
00:27.160 --> 00:31.090
sort of jump in and just get our feet wet a little bit with some of the other

8
00:31.090 --> 00:31.560
topics

9
00:31.560 --> 00:34.280
that we're going to be discussing throughout the skill.

10
00:34.280 --> 00:40.200
Then we're going to move on to talking in more detail about TCP optimization

11
00:40.200 --> 00:40.360
and the

12
00:40.360 --> 00:43.880
features available with that technology.

13
00:43.880 --> 00:47.600
Then we're going to talk about data redundancy elimination.

14
00:47.600 --> 00:51.970
One of the things, of course, that can cause performance issues on our WAN is

15
00:51.970 --> 00:53.240
sending redundant

16
00:53.240 --> 00:54.320
data.

17
00:54.320 --> 00:57.440
So we want to eliminate that whenever possible.

18
00:57.440 --> 01:01.920
But then we're going to move on to packet duplication, which, well, that's sort

18
00:57.440 --> 01:01.920
But then we're going to move on to packet duplication, which, well, that's sort

19
01:01.920 --> 01:02.120
of the

20
01:02.120 --> 01:07.760
opposite here because we're going to be sending duplicate packets on purpose.

21
01:07.760 --> 01:08.760
Why would we do that?

22
01:08.760 --> 01:11.560
Well, we'll talk about it when we get there.

23
01:11.560 --> 01:16.270
But then we're going to wrap up with forward error correction, which is error

24
01:16.270 --> 01:17.080
correction

25
01:17.080 --> 01:19.320
for lost packets.

26
01:19.320 --> 01:23.680
Specifically, it's data recovery using parity.

27
01:23.680 --> 01:28.040
So as you can hear, we have a lot of really cool stuff to cover in this skill.

28
01:28.040 --> 01:29.720
So join me as we jump in.

29
01:29.720 --> 01:31.960
I'll see you in the next video.
