1 00:00:04,600 --> 00:00:07,420 My Welcome back let's get the show on the road. 2 00:00:07,650 --> 00:00:12,480 So I again introduction to the TC VIP section. 3 00:00:12,690 --> 00:00:15,370 All right now what we're going to do in this particular section. 4 00:00:15,870 --> 00:00:22,570 It's all over about the TZP ABC was designed and implemented by the Department of Defense. 5 00:00:22,590 --> 00:00:30,610 Yes they're the ones that did it way back in the day in case of anything happens during a call or not 6 00:00:30,710 --> 00:00:36,420 in a wartime situation we would still be able to communicate with each other. 7 00:00:36,420 --> 00:00:37,030 All right. 8 00:00:37,200 --> 00:00:40,760 He's a baby at the very core of all things in networking. 9 00:00:40,760 --> 00:00:44,520 All right is the very core of all networking things. 10 00:00:44,610 --> 00:00:52,130 So you really need to have a comprehensive and functional command of it meaning you need to understand 11 00:00:52,770 --> 00:00:53,880 what's it for. 12 00:00:54,060 --> 00:00:54,870 OK what do we need. 13 00:00:54,870 --> 00:01:00,440 What do we need to understand because when you're troubleshooting you need to understand is what layer 14 00:01:00,500 --> 00:01:03,440 am I learning to your our money initially. 15 00:01:03,560 --> 00:01:04,240 OK. 16 00:01:04,260 --> 00:01:05,350 Is it. 17 00:01:05,440 --> 00:01:07,080 Is this the application layer. 18 00:01:07,180 --> 00:01:10,180 Is it the transporter or a WHOLE SHOW HOST Where is the Internet. 19 00:01:10,190 --> 00:01:11,380 There is a network access. 20 00:01:11,380 --> 00:01:18,280 There's a link where what layer am I running into so I know what I need to swap. 21 00:01:18,440 --> 00:01:19,300 OK. 22 00:01:19,800 --> 00:01:22,100 And how should I look at it. 23 00:01:22,380 --> 00:01:25,080 Now that I know more or less what's going on. 24 00:01:25,080 --> 00:01:30,600 So you really need to have a really good solid foundation on TGP being one of the key topics we need 25 00:01:30,600 --> 00:01:34,020 to understand is how to teach you about the model error's map over. 26 00:01:34,230 --> 00:01:39,810 Yes because the TV model was the original model we had our layers there are four layers and that's what 27 00:01:39,810 --> 00:01:40,520 we went through. 28 00:01:40,650 --> 00:01:46,980 But it was very not only with a vague but general in a sense that a lot of things work on one layer. 29 00:01:46,980 --> 00:01:50,880 So they made it even more granular in the site. 30 00:01:50,910 --> 00:01:53,380 They made seven letters. 31 00:01:53,410 --> 00:01:59,960 Why you have your physical area datalink where you have your network where right and you keep going 32 00:01:59,970 --> 00:02:02,150 up you know you're trying to force them and all that. 33 00:02:02,160 --> 00:02:03,100 I mean so. 34 00:02:03,530 --> 00:02:11,270 Session where you have all these different things in all these years that they are responsible for and 35 00:02:11,270 --> 00:02:20,390 you as a network engineer or a network technician and network person period that deals now or tell you 36 00:02:20,390 --> 00:02:21,690 what I mean. 37 00:02:21,960 --> 00:02:23,400 Yes I do. 38 00:02:23,600 --> 00:02:25,600 Jane you know on an hours I look real quickly. 39 00:02:25,610 --> 00:02:25,930 OK. 40 00:02:25,940 --> 00:02:26,440 Good job. 41 00:02:26,440 --> 00:02:27,070 That's not reality. 42 00:02:27,080 --> 00:02:28,280 But I'll give you a job. 43 00:02:28,280 --> 00:02:29,000 OK let's go. 44 00:02:29,120 --> 00:02:34,310 So you need to get a good understanding because if you don't understand this then how are you going 45 00:02:34,310 --> 00:02:35,480 to attack an issue. 46 00:02:35,540 --> 00:02:37,330 What do you think the problem's going to be. 47 00:02:37,340 --> 00:02:41,930 Hey I can't get to the Internet or I can't print. 48 00:02:42,020 --> 00:02:42,910 Let me check the printer. 49 00:02:42,920 --> 00:02:44,030 Why are you going to check the printer. 50 00:02:44,030 --> 00:02:46,020 Why don't you check even for that connectivity. 51 00:02:46,350 --> 00:02:46,890 All right. 52 00:02:47,000 --> 00:02:50,330 This is the kind of thing that I'm talking about that's why this is very important. 53 00:02:50,330 --> 00:02:57,500 There's this foundation on 9:21 maps or to the voice I because we're more now for Miller with the website. 54 00:02:57,560 --> 00:03:04,060 Cisco is bringing back now a new five letter model though we will be looking into. 55 00:03:04,130 --> 00:03:12,880 Now I said we're a lot of very brief history first came on the scene in 1973 two or six years old. 56 00:03:13,070 --> 00:03:14,360 And this thing around. 57 00:03:14,590 --> 00:03:15,320 OK. 58 00:03:15,560 --> 00:03:18,770 In 1978 it was divided into two distinct protocols. 59 00:03:18,800 --> 00:03:25,470 TCAP are going to say they're either holding a connection oriented an IP connection less. 60 00:03:25,810 --> 00:03:26,830 Eighty three. 61 00:03:26,860 --> 00:03:28,450 Nineteen eighty three. 62 00:03:28,560 --> 00:03:30,140 He was replaced. 63 00:03:30,140 --> 00:03:33,660 Replace them or replace the NCP. 64 00:03:33,670 --> 00:03:39,740 They were controversial as and was authorized as official means of data transport for anything connecting 65 00:03:39,740 --> 00:03:41,830 to the ARPA net. 66 00:03:42,080 --> 00:03:44,570 So now it's no longer NCB. 67 00:03:44,570 --> 00:03:52,230 Now it's TCAP you remember not even that long ago where have you had an apple use Apple talk about NetWare. 68 00:03:52,230 --> 00:03:54,540 Not in the blink of an eye in the remake. 69 00:03:55,540 --> 00:03:57,160 A while. 70 00:03:57,230 --> 00:03:59,830 Well you know Microsoft got into meaning. 71 00:04:00,040 --> 00:04:00,290 Yeah. 72 00:04:00,300 --> 00:04:05,720 All these different protocols that you had to have in order for them to be able to talk to each other. 73 00:04:05,730 --> 00:04:09,120 Now is the IP period. 74 00:04:09,450 --> 00:04:17,730 Everybody in the world uses TCAP IP so you need to understand OK most of the development work on that 75 00:04:17,730 --> 00:04:20,390 is TZP have an ad that you use. 76 00:04:20,400 --> 00:04:22,950 University of Berkeley in northern California. 77 00:04:23,160 --> 00:04:30,800 OK TZP work Soilwork package it to subsequent releases with us and offered to other universities as 78 00:04:31,090 --> 00:04:37,200 they wish they bother if they are other distribution tape and they became the foundation for the tremendous 79 00:04:37,200 --> 00:04:40,860 success and unprecedented growth of today's Internet. 80 00:04:41,050 --> 00:04:46,520 If the IP is what made the internet it is the protocol of the Internet. 81 00:04:46,590 --> 00:04:49,200 That's how we get to where we need to go. 82 00:04:49,400 --> 00:04:51,610 Right is TZP IP. 83 00:04:51,630 --> 00:04:56,530 It is essential because it breaks down everything that we need to know. 84 00:04:56,580 --> 00:05:02,910 And that's why we map things over to the oys high model we Matthijs over to all the different than the 85 00:05:02,910 --> 00:05:08,640 old all the original V.I.P model to the new TBP model. 86 00:05:08,700 --> 00:05:10,620 We need to know. 87 00:05:10,860 --> 00:05:12,800 You need to know or sort of occasion purposes. 88 00:05:12,810 --> 00:05:16,950 Yes but this is more for a real world type scenario. 89 00:05:17,220 --> 00:05:23,790 You will use it in telecommunications when we would check communications between the switch and the 90 00:05:23,790 --> 00:05:28,300 cell tower or the routers that existed underneath the cell tower. 91 00:05:28,500 --> 00:05:33,450 We did checks and there were layer two checks we were armed to see when we get anything back and we 92 00:05:33,450 --> 00:05:34,260 didn't pay. 93 00:05:34,410 --> 00:05:38,520 It could have been that particular connector that was there that was messed up it could have been a 94 00:05:38,520 --> 00:05:39,410 raw idea. 95 00:05:39,420 --> 00:05:43,320 Or is it going to be a million different thing that was wrong. 96 00:05:43,320 --> 00:05:45,060 But we did our checks. 97 00:05:45,240 --> 00:05:45,790 OK. 98 00:05:45,960 --> 00:05:47,960 And we need to know what we were looking at. 99 00:05:48,180 --> 00:05:55,560 Obviously the software that you're going to use is some sort of third party software that's going to 100 00:05:55,560 --> 00:05:59,310 help you make it easier to understand what's going on. 101 00:05:59,310 --> 00:06:03,820 So let you know hey so going on here are not receiving. 102 00:06:04,050 --> 00:06:10,920 To guide you along the way but definitely you need to understand now really you know hey it's cool. 103 00:06:10,920 --> 00:06:13,850 You know party talk and talk about this in a party. 104 00:06:13,860 --> 00:06:15,000 I'm sorry for you. 105 00:06:15,270 --> 00:06:20,610 But hey at least you know I was talking to party in the I.T. world. 106 00:06:21,420 --> 00:06:28,710 You know the day today started and when it replays the NCP for recall and then also in the 80s he became 107 00:06:28,710 --> 00:06:29,770 the foundation. 108 00:06:29,850 --> 00:06:31,400 So nice it makes you look good. 109 00:06:31,470 --> 00:06:32,080 OK. 110 00:06:32,250 --> 00:06:38,430 But the rest of it as far as getting the understanding of what it does specially for troubleshooting 111 00:06:38,460 --> 00:06:42,210 purposes is really important. 112 00:06:42,260 --> 00:06:43,120 All right. 113 00:06:43,170 --> 00:06:45,350 So we came from 1973. 114 00:06:45,390 --> 00:06:46,620 OK. 115 00:06:47,130 --> 00:06:55,370 And forget that I was thinking over the phone do the math in 1973 and in 78 it was two different verticals. 116 00:06:55,380 --> 00:06:56,740 That's why they call it sweet. 117 00:06:56,840 --> 00:06:58,960 They're full of articles and sweet. 118 00:06:59,190 --> 00:07:00,030 OK. 119 00:07:00,090 --> 00:07:02,130 All right then I'll show you in actual.
