1
00:00:04,430 --> 00:00:10,760
Work on everybody to the GCB be courts aren't.

2
00:00:10,830 --> 00:00:16,850
There's a lot of things that we need to understand about TZP IP since it's a suite of protocols.

3
00:00:17,100 --> 00:00:23,130
So through the course in its different sections we well first of all yes we'll look at just a brief

4
00:00:23,130 --> 00:00:24,400
history which is interesting.

5
00:00:24,420 --> 00:00:28,050
We're going to get to ing death or anything like that but it's something you should know where it came

6
00:00:28,050 --> 00:00:28,610
from.

7
00:00:28,970 --> 00:00:30,360
Was it meant to be for the other.

8
00:00:30,360 --> 00:00:36,510
We're talking about way back in the 50s and 60s and 70s and then IP comes off.

9
00:00:36,570 --> 00:00:37,280
OK.

10
00:00:37,500 --> 00:00:40,300
Remember that TZP is all always connection oriented.

11
00:00:40,300 --> 00:00:45,990
An IP connection unless they both have their all purpose.

12
00:00:45,990 --> 00:00:48,770
That's why they're called A sweet.

13
00:00:48,960 --> 00:00:54,100
That's why they call these stack Easy-Bake stack because there are different things that they do.

14
00:00:54,120 --> 00:01:02,120
Now one will be comparing the TZP model to the side and to a new or finer layer.

15
00:01:02,480 --> 00:01:03,010
OK.

16
00:01:03,030 --> 00:01:07,360
Before that is going to be model or DVD as they like to call it.

17
00:01:07,360 --> 00:01:11,440
And there was the deal who started this whole thing.

18
00:01:12,270 --> 00:01:14,410
There were four letters original.

19
00:01:14,520 --> 00:01:15,080
OK.

20
00:01:15,300 --> 00:01:17,580
And now is really for.

21
00:01:17,580 --> 00:01:20,040
They just broke it up into a fight.

22
00:01:20,110 --> 00:01:23,340
Think layers layer's same means nothing different.

23
00:01:23,340 --> 00:01:25,980
They just want to be a little bit more granular.

24
00:01:26,220 --> 00:01:34,950
If for today's standards OK we'll look at how the layers map to all the different models.

25
00:01:35,640 --> 00:01:46,970
We're on the oil side being the first one then the original TCAP model and then the newest model will

26
00:01:46,980 --> 00:01:48,290
be breaking down different layers.

27
00:01:48,320 --> 00:01:54,180
That is the model and also we'll be discussing the ports because remember not only do you need a source

28
00:01:54,540 --> 00:02:01,200
IP destination IP source Mac destination MAC you need a port number one time for numbers.

29
00:02:01,200 --> 00:02:07,650
Obviously there's well-known four numbers that we use on a daily basis that we're not aware of like

30
00:02:07,650 --> 00:02:10,190
telnet or S-sh or HDTV.

31
00:02:10,350 --> 00:02:17,100
All the or SMG all the we need to know that they're obviously working in the application layer but we'll

32
00:02:17,100 --> 00:02:19,920
take a look at those port numbers as we get there.

33
00:02:19,950 --> 00:02:23,990
Most importantly will be the addressing.

34
00:02:24,210 --> 00:02:26,410
Is the IP portion model.

35
00:02:26,520 --> 00:02:27,430
Yes.

36
00:02:27,870 --> 00:02:32,070
We're going to go ahead whether or not you can get away from it.

37
00:02:32,180 --> 00:02:32,870
Okay.

38
00:02:33,070 --> 00:02:34,560
It's IP.

39
00:02:34,680 --> 00:02:35,240
Okay.

40
00:02:35,350 --> 00:02:41,550
You can't get away from IP when I say IP I mean IP addressing now or there's some terminology that you

41
00:02:41,550 --> 00:02:42,720
need to understand.

42
00:02:42,750 --> 00:02:43,460
Okay.

43
00:02:43,680 --> 00:02:47,410
There's an earthquake plane the flat versus a high art.

44
00:02:47,470 --> 00:02:49,550
Tickle everybody for word.

45
00:02:49,950 --> 00:02:55,800
So you know what the differences are what the advantage is is our net worth in class ranges and private

46
00:02:55,800 --> 00:02:56,340
IP address.

47
00:02:56,350 --> 00:03:05,790
Basically I'm using a brief but a good solid foundation of IP because if you do not know IP addressing

48
00:03:07,140 --> 00:03:10,610
whether what's a gateway do we need a gateway more.

49
00:03:10,740 --> 00:03:15,020
So what if it doesn't have the same something in math just put whatever you want in there.

50
00:03:15,030 --> 00:03:19,670
I don't know put all zeros put 169 through the fourth.

51
00:03:19,710 --> 00:03:21,420
You need to know.

52
00:03:21,680 --> 00:03:28,860
You know we watch IPs are going to be a broadcast that we are not going to be ridable on the Internet

53
00:03:29,330 --> 00:03:31,170
IPs that are reserved.

54
00:03:31,320 --> 00:03:33,470
OK you need to know about that.

55
00:03:33,630 --> 00:03:37,090
Is this a multicast and who uses multicast.

56
00:03:37,090 --> 00:03:38,510
Is is a broadcast.

57
00:03:38,550 --> 00:03:41,940
Why would you use a broadcast where routers by default don't accept that.

58
00:03:42,090 --> 00:03:44,200
So there's a lot of things that we're going to cover.

59
00:03:44,210 --> 00:03:52,740
There's a lot to be huge of course but it will give you a very solid foundation to help you move forward

60
00:03:53,040 --> 00:03:55,550
in your networking career.

61
00:03:55,590 --> 00:03:55,730
You.
