 Hello and welcome to this course titled
 Enhancing Network Operations with

0:00:12.360000 --> 0:00:17.400000
 QOS. My name is Keith Bogart and I'll
 be your instructor for the duration

0:00:17.400000 --> 0:00:21.200000
 of this course. I've provided my contact
 information here in the slides

0:00:21.200000 --> 0:00:25.380000
 so after watching these videos if you
 still have any questions please

0:00:25.380000 --> 0:00:27.920000
 feel free to reach out to me.

0:00:27.920000 --> 0:00:30.660000
 So what are the objectives
 of this course?

0:00:30.660000 --> 0:00:35.700000
 Well, real high level number one I
 want to explain why we need QOS in

0:00:35.700000 --> 0:00:37.360000
 today's networks.

0:00:37.360000 --> 0:00:41.640000
 This course is specifically designed
 for someone with zero knowledge or

0:00:41.640000 --> 0:00:45.320000
 experience with quality of service and
 I want to help you get you going

0:00:45.320000 --> 0:00:49.920000
 with understanding why we need the
 various features that QOS provides.

0:00:49.920000 --> 0:00:53.320000
 Also, there's a lot of terminology
 that goes with QOS.

0:00:53.320000 --> 0:00:56.580000
 A lot of acronyms, a lot of features
 and protocols that I want you to

0:00:56.580000 --> 0:01:00.220000
 be familiar with their names
 as we go along here.

0:01:00.220000 --> 0:01:04.840000
 And then also lastly, I want to give you
 exposure to some common QOS techniques.

0:01:04.840000 --> 0:01:10.580000
 Right now when I throw out terms like
 policing, traffic shaping, markdown,

0:01:10.580000 --> 0:01:14.180000
 queuing and scheduling those might
 mean nothing to you but by the time

0:01:14.180000 --> 0:01:17.980000
 you're done with this series of videos
 you will know what those terms

0:01:17.980000 --> 0:01:23.540000
 mean. Now, there are just a couple
 of very basic prerequisites that go

0:01:23.540000 --> 0:01:26.580000
 along with this course so you can gain
 the maximum amount of learning

0:01:26.580000 --> 0:01:30.920000
 possible. Number one, you should have
 a basic understanding of how routers

0:01:30.920000 --> 0:01:34.180000
 and switches forward IP packets.

0:01:34.180000 --> 0:01:37.520000
 So you should know what a routing table
 is, what a switching table is.

0:01:37.520000 --> 0:01:41.760000
 You should also have familiarity
 with the IPV4 packet headers.

0:01:41.760000 --> 0:01:45.520000
 I'm going to frequently refer to that
 throughout the various videos in

0:01:45.520000 --> 0:01:48.760000
 this course. So that concludes
 this course introduction.

0:01:48.760000 --> 0:01:51.540000
 Let's just go ahead and jump right
 in to learning about the basics of

0:01:51.540000 --> 0:01:52.760000
 quality of service.
