1 00:00:04,440 --> 00:00:05,340 All right. 2 00:00:05,500 --> 00:00:06,080 Well I'm back. 3 00:00:06,090 --> 00:00:07,590 Let's get into it. 4 00:00:07,590 --> 00:00:13,890 Let's get a visualization and legacy that where I got this was from Cisco's this C.S. CCN as anyone 5 00:00:14,190 --> 00:00:15,920 wanted at 25 a visual guide. 6 00:00:15,930 --> 00:00:18,540 I got this image from their book. 7 00:00:18,600 --> 00:00:19,870 Yes I did. 8 00:00:20,020 --> 00:00:20,590 All right. 9 00:00:20,610 --> 00:00:22,820 Because they are the ones they're putting this out. 10 00:00:22,830 --> 00:00:24,380 So I'm giving you the information. 11 00:00:24,430 --> 00:00:25,660 All right. 12 00:00:26,280 --> 00:00:28,600 Here we see our oil model. 13 00:00:28,620 --> 00:00:29,980 We have seven layers. 14 00:00:30,150 --> 00:00:33,270 You have the application the intelligence engine transport network doing physical. 15 00:00:33,270 --> 00:00:35,700 All people seem to need Domino's Pizza. 16 00:00:35,700 --> 00:00:37,330 That's the way I remember it. 17 00:00:37,650 --> 00:00:43,690 Every single time all people seem to need doublespeak So we you more scientific minds. 18 00:00:43,740 --> 00:00:45,410 All people need. 19 00:00:45,540 --> 00:00:52,130 All people seem to need data processing whatever word makes you happy as long as you remember it we're 20 00:00:52,140 --> 00:00:52,950 OK. 21 00:00:53,120 --> 00:00:53,920 All right. 22 00:00:54,270 --> 00:00:58,330 As you can see now before we keep going. 23 00:00:58,360 --> 00:01:00,090 We keep calling this TZP happy. 24 00:01:00,100 --> 00:01:00,880 That's what it is. 25 00:01:01,120 --> 00:01:06,780 But they also call it the deal the mom because one of the first was the one that created it. 26 00:01:06,800 --> 00:01:09,830 They try to take there when we're up on our name on it. 27 00:01:10,040 --> 00:01:11,010 And then this. 28 00:01:11,330 --> 00:01:15,600 They came out the powers that be came out and said that these if every month. 29 00:01:15,710 --> 00:01:16,560 OK. 30 00:01:16,810 --> 00:01:18,740 Well the Eleusis or whatever. 31 00:01:18,740 --> 00:01:19,290 All right. 32 00:01:19,310 --> 00:01:22,180 So anyway so the office model. 33 00:01:22,530 --> 00:01:31,220 Anything that happens in these three layers maps all over to both the Old and Neal TZP IP model in the 34 00:01:31,220 --> 00:01:32,030 application layer. 35 00:01:32,030 --> 00:01:40,100 So when you're talking about the application layer you're talking about a.p as NCP c.a.p telnet DNS 36 00:01:40,190 --> 00:01:44,730 all these things are they that you would check on here or invasion. 37 00:01:44,780 --> 00:01:46,300 Anything beyond the formatting. 38 00:01:46,460 --> 00:01:49,660 OK encryption Niekro isn't all that right here. 39 00:01:49,700 --> 00:01:52,860 Session Dyalog control right. 40 00:01:53,930 --> 00:01:55,140 Dialog control. 41 00:01:55,240 --> 00:01:59,140 OK so last in your troubleshooting. 42 00:01:59,150 --> 00:02:01,310 For whatever reason portrait numbers in nature. 43 00:02:01,310 --> 00:02:02,630 There you go right there. 44 00:02:03,860 --> 00:02:15,440 The Akbar's three lines of the Oist I model maps or to boil the all and new CCP IP model. 45 00:02:15,560 --> 00:02:16,300 OK. 46 00:02:16,520 --> 00:02:25,100 Application layer the transport all the way across transport all the way across those two poles where 47 00:02:25,370 --> 00:02:27,500 you should be called but it's a transport layer. 48 00:02:27,500 --> 00:02:40,520 So athing dealing with TZP uty segmentation why windowing acknowledgements all these things Yuriko it's 49 00:02:40,520 --> 00:02:42,430 happening right here. 50 00:02:42,470 --> 00:02:43,380 OK. 51 00:02:43,850 --> 00:02:51,770 I think earlier on when we get to an hourglass or look at network internet but now in the newer model 52 00:02:52,070 --> 00:02:54,450 they don't call it Internet now they call an hour 53 00:02:57,670 --> 00:02:58,500 whatever. 54 00:02:58,800 --> 00:02:59,460 OK. 55 00:02:59,550 --> 00:03:13,310 And now our new model so off is Larry no burglar all these new IP model Internet new TCAP at new TZP 56 00:03:13,650 --> 00:03:16,980 T-model network OK. 57 00:03:17,290 --> 00:03:18,220 What happens there. 58 00:03:18,220 --> 00:03:24,940 There we deal with routers there with the idea addressing the other routing protocol to routing protocols 59 00:03:25,420 --> 00:03:34,630 importante very unique you know this routing protocol where we'll get to docilely because it depends 60 00:03:34,890 --> 00:03:39,150 while writing port to call using our is doesn't vector are using a lengthy. 61 00:03:39,250 --> 00:03:41,470 Is it a path back there like BGP. 62 00:03:41,680 --> 00:03:44,240 OK what is it that you're using or SPF. 63 00:03:44,260 --> 00:03:46,750 Are you using multiple area single area. 64 00:03:46,870 --> 00:03:48,740 Are we doing redistribution. 65 00:03:48,770 --> 00:03:52,930 Are we doing Rahmat all these different things right in here. 66 00:03:54,040 --> 00:03:55,680 OK right here. 67 00:03:55,830 --> 00:03:57,210 They don't like that. 68 00:03:57,360 --> 00:04:01,930 I want you to take a look at the debt ceiling and the physical as you can see here in the on and math 69 00:04:01,940 --> 00:04:03,140 right to Legler. 70 00:04:03,240 --> 00:04:07,510 But in the new one they broke it up into two. 71 00:04:07,630 --> 00:04:09,390 They my or Bolpur it. 72 00:04:09,600 --> 00:04:13,850 They don't leak and fail to go because that's your connectivity right there. 73 00:04:13,900 --> 00:04:18,640 Frame's so switches labeling beds. 74 00:04:18,810 --> 00:04:21,690 All that stuff is right down here. 75 00:04:21,720 --> 00:04:22,380 OK. 76 00:04:24,230 --> 00:04:29,160 So if you can't get through your day with it it is make it simple. 77 00:04:29,240 --> 00:04:30,430 You can't get there. 78 00:04:30,440 --> 00:04:31,800 What do you need to get through gateway. 79 00:04:31,830 --> 00:04:41,050 And I believe our we know we have to do what our goals we need what our destination MAC address and 80 00:04:41,050 --> 00:04:44,430 Mac address as we know is staging its own segment. 81 00:04:44,440 --> 00:04:46,120 They don't go across the network. 82 00:04:46,940 --> 00:04:52,290 So this is what we were testing and we're getting a reply. 83 00:04:52,700 --> 00:04:58,800 If you're getting that framing coming now because if you don't and you don't complete it I know my IP 84 00:04:58,820 --> 00:04:59,330 address. 85 00:04:59,450 --> 00:05:00,950 I know my Some in math. 86 00:05:01,070 --> 00:05:03,710 I know my gateway address. 87 00:05:03,820 --> 00:05:08,090 I know my mac address what's my destination MAC address. 88 00:05:08,110 --> 00:05:11,600 Was that router right there that you're plugged into. 89 00:05:12,030 --> 00:05:16,080 Ok I need that in order to get to it. 90 00:05:16,080 --> 00:05:21,320 So then the router really make a decision and layer 3 OK. 91 00:05:21,370 --> 00:05:28,750 Look at his writing table and say OK I know you you're one of these like 3.0. 92 00:05:28,930 --> 00:05:30,380 I'm going to send you over. 93 00:05:30,640 --> 00:05:34,900 And they're counting on his feet and that is he can I get through if I see them. 94 00:05:34,960 --> 00:05:36,130 Is can I get the gigabit. 95 00:05:36,160 --> 00:05:37,480 Is he connected to wireless. 96 00:05:37,520 --> 00:05:39,270 Is a coaxial. 97 00:05:39,340 --> 00:05:40,470 Is it infrared. 98 00:05:40,630 --> 00:05:41,470 There's a satellite. 99 00:05:41,470 --> 00:05:42,300 I don't know. 100 00:05:42,310 --> 00:05:42,790 All right. 101 00:05:42,790 --> 00:05:47,490 Depending on the media depending on the type of information one other house is going out there. 102 00:05:47,950 --> 00:05:48,800 OK. 103 00:05:49,210 --> 00:05:58,100 But just to keep it simple everything there that are before it it's cereal. 104 00:05:58,150 --> 00:06:01,310 There is no more so than just sends the that information across. 105 00:06:01,630 --> 00:06:02,480 OK. 106 00:06:02,950 --> 00:06:03,940 All right. 107 00:06:04,210 --> 00:06:09,870 And you can tell as well here you know because normally believe it or not real world real world those 108 00:06:09,880 --> 00:06:10,930 are thorny Laz's. 109 00:06:10,980 --> 00:06:11,910 This is the real world. 110 00:06:11,980 --> 00:06:23,600 Yes telecommunications major corporations leaving their cabinets all pain be driving on the road. 111 00:06:23,790 --> 00:06:26,560 You know cell tower will down. 112 00:06:26,860 --> 00:06:28,110 You see the cabin wide open. 113 00:06:28,960 --> 00:06:30,220 Pouring rain. 114 00:06:30,640 --> 00:06:39,140 He was plugged into the panels in there the larders exposed pouring down rain. 115 00:06:40,250 --> 00:06:46,380 Real world non-terminating Well they swore that they did 116 00:06:49,400 --> 00:06:50,450 did you switch off the board. 117 00:06:50,450 --> 00:06:51,080 I sure did. 118 00:06:51,080 --> 00:06:58,310 I thought that board game board OK how do we know this because somebody went out there put a little 119 00:06:58,970 --> 00:06:59,830 dot on there. 120 00:06:59,900 --> 00:07:01,190 So hey any just which other board. 121 00:07:01,250 --> 00:07:01,880 OK. 122 00:07:02,010 --> 00:07:02,540 None. 123 00:07:02,600 --> 00:07:02,950 All right. 124 00:07:02,960 --> 00:07:07,890 One other than if they say more of this will not sell real world. 125 00:07:08,740 --> 00:07:10,400 All you need to know are you looking at. 126 00:07:10,430 --> 00:07:11,830 We're going to be looking at. 127 00:07:12,100 --> 00:07:17,290 So you look at it here's your TZP IBM Model or the old the model whatever makes you happy wherever you 128 00:07:17,290 --> 00:07:18,480 want to call it. 129 00:07:18,490 --> 00:07:19,180 All right. 130 00:07:19,180 --> 00:07:24,370 The process of an application layer goes processes where I tell that. 131 00:07:24,410 --> 00:07:34,890 But Dell is just walking down the rabbit hole goes down later on telnet FTT Albine S M P P P P and there 132 00:07:34,890 --> 00:07:38,850 is more than just the ATP as NMT as a.p. 133 00:07:38,890 --> 00:07:42,600 Oh my God is abreviation And if X and X window Y. 134 00:07:42,610 --> 00:07:46,910 We know the majority I'm going to put things that we normally use like as SMPTE. 135 00:07:46,920 --> 00:07:54,630 Tell that FTB you have the pain in the ass up here or in the host to host or transport. 136 00:07:54,760 --> 00:07:58,160 We have GCP connection oriented. 137 00:07:58,390 --> 00:08:05,350 It makes sure that the information that you're sending is getting is getting there and knows how to 138 00:08:05,350 --> 00:08:10,390 get there because why you know acknowledgements that you write to get information. 139 00:08:10,480 --> 00:08:10,740 Yes. 140 00:08:10,750 --> 00:08:11,080 Good luck. 141 00:08:11,080 --> 00:08:12,730 I'm going to send you to ribeyes OK. 142 00:08:12,850 --> 00:08:16,540 I want to acknowledge if you need another one and I want to keep telling you about why we have this 143 00:08:16,540 --> 00:08:22,930 three way handshake that's going on with TZP because it wants to make sure that the window side that 144 00:08:22,930 --> 00:08:30,040 you're able to handle the information it would just automatically for you to send all the data that 145 00:08:30,040 --> 00:08:32,520 you need you to be like. 146 00:08:32,980 --> 00:08:34,560 Well I think I got it. 147 00:08:35,410 --> 00:08:37,760 It doesn't really know it's connection oriented. 148 00:08:38,020 --> 00:08:51,660 We use you be or not you have to be use UDP DNS use bold DNS uses both physically and UDP Wang there's 149 00:08:51,660 --> 00:09:00,780 a usable way we use a TZP was doing any kind of DNS between domain controllers replication or any major 150 00:09:00,780 --> 00:09:02,520 thing as above a hundred and twelve bytes. 151 00:09:02,520 --> 00:09:09,680 Right but if it's under any unit it really for a user unity you're looking for a printer UniFi I be 152 00:09:09,690 --> 00:09:15,440 doing something major to the internet nutter network. 153 00:09:15,470 --> 00:09:16,120 Right. 154 00:09:16,360 --> 00:09:18,220 I see Impey are. 155 00:09:18,360 --> 00:09:25,730 We'll use We're going to configure a server we're you know reverse address or no are or ok. 156 00:09:25,830 --> 00:09:27,790 I think the pinging that's where it is. 157 00:09:27,790 --> 00:09:30,900 Trace route tracer path ping whatever Do we want to call it. 158 00:09:30,960 --> 00:09:31,520 OK. 159 00:09:31,650 --> 00:09:35,110 And I think the Sixth Pay we know more about Arbre anymore do we. 160 00:09:35,130 --> 00:09:37,420 But I think also runs in there as well. 161 00:09:37,580 --> 00:09:45,400 OK and all the running portable and all all the all the routers and layer 3 switches there. 162 00:09:45,520 --> 00:09:46,990 What about Ellerslie switch. 163 00:09:47,020 --> 00:09:49,590 Listen you have alerts the switch. 164 00:09:50,280 --> 00:09:51,330 I'm happy for you. 165 00:09:51,420 --> 00:09:52,890 You have routing capabilities. 166 00:09:53,070 --> 00:09:53,650 OK. 167 00:09:53,780 --> 00:09:54,200 That's it. 168 00:09:54,210 --> 00:09:56,150 Let me deal with your company. 169 00:09:56,190 --> 00:10:02,390 You better have a very good router if you want to network entire enterprise. 170 00:10:02,580 --> 00:10:09,410 You may have your core routers and then you're like your Cisco dealer model that change as well. 171 00:10:09,650 --> 00:10:10,780 But we're not going to get into that. 172 00:10:10,920 --> 00:10:13,160 But you have your core routers right. 173 00:10:13,320 --> 00:10:20,880 You have your distribution routers which could include switches and then you have your axis switches 174 00:10:21,150 --> 00:10:25,710 which could be Larry Orlean's it was really up to you at home how you want to use it because you can 175 00:10:25,710 --> 00:10:31,860 enable or disable the routing functionality and just be alert to switch. 176 00:10:32,020 --> 00:10:36,910 Ok but here in the network access we're talking about even faster than a gigabit ethernet. 177 00:10:36,910 --> 00:10:37,550 All right. 178 00:10:37,650 --> 00:10:41,710 Taking our time off some backbones right. 179 00:10:41,790 --> 00:10:46,770 We're not just talking about simple networking in the classroom or between floors and anything like 180 00:10:46,770 --> 00:10:52,250 that with them on between buildings or cross you know going far far away. 181 00:10:52,380 --> 00:10:53,020 All right. 182 00:10:53,160 --> 00:10:56,770 So this is your new model these other layers. 183 00:10:56,790 --> 00:11:04,140 This is the one I really want you to pay attention to because it shows you the comparison of all three. 184 00:11:04,140 --> 00:11:06,470 They're both the S.E.C. IP. 185 00:11:06,660 --> 00:11:13,940 But now this is the latest and greatest of that system made up all the TCAP IP model right here. 186 00:11:14,210 --> 00:11:15,270 OK same thing. 187 00:11:15,270 --> 00:11:17,090 Application transport. 188 00:11:17,160 --> 00:11:21,020 Now its network and sort of just link its data link and physical. 189 00:11:21,060 --> 00:11:29,050 They kind of separate it but as you can see they still map over will sing OK. 190 00:11:29,580 --> 00:11:33,850 So you know all is you know what happens on each layer. 191 00:11:34,730 --> 00:11:35,430 OK. 192 00:11:35,640 --> 00:11:37,480 Now just nap more. 193 00:11:37,560 --> 00:11:39,840 You know what happens on each other as well. 194 00:11:39,840 --> 00:11:40,520 All right. 195 00:11:41,820 --> 00:11:43,210 For watching the next.
