1 00:00:09,560 --> 00:00:15,310 Love everyone it is my that here again in this first lecture of the quality of service today. 2 00:00:15,350 --> 00:00:20,870 I want to give you an explanation about how the quality of service or what we call the Ashtiani works 3 00:00:20,870 --> 00:00:21,890 on my. 4 00:00:22,130 --> 00:00:29,300 So I have made this slide to summarize many points inside this topic and I'll go through them one by 5 00:00:29,300 --> 00:00:33,460 one and then I go to do some examples when we want to work on the priority. 6 00:00:33,470 --> 00:00:35,090 So what is there to be. 7 00:00:35,090 --> 00:00:40,820 Actually the quality of service on my take is based on HTB actually is hierarchical token bucket. 8 00:00:40,850 --> 00:00:43,750 So all the quality of service is based on that. 9 00:00:43,760 --> 00:00:49,210 And if we go back to the picture that I was showing you before about the packet flow. 10 00:00:49,370 --> 00:00:54,020 So if we go here we can see that the SUV was showing up over here at the pace. 11 00:00:54,020 --> 00:00:56,460 STV Okay. 12 00:00:56,550 --> 00:00:58,830 And you can see it is on the output of the device. 13 00:00:58,830 --> 00:01:04,660 That means that we cannot control the quality of service of the traffic coming to us. 14 00:01:04,710 --> 00:01:09,870 We can only control the traffic that is going from our interface and then we can do with the quality 15 00:01:09,870 --> 00:01:10,410 of service. 16 00:01:10,410 --> 00:01:17,640 So here it says that the quality of service with the FTB we can create something we call hierarchical 17 00:01:17,640 --> 00:01:19,730 queue for parent and child use. 18 00:01:19,770 --> 00:01:26,050 So that means that using the HTB you can say I want to create the first Q And this is the part that 19 00:01:26,070 --> 00:01:27,190 you and I want to give it. 20 00:01:27,240 --> 00:01:34,980 As for example that log of 8 megabits per second and then on this you make some use which are called 21 00:01:35,190 --> 00:01:42,150 child abuse and then you can say for this computer for example I want to give him to me of it for then 22 00:01:42,150 --> 00:01:47,050 you make another do for the other computer I want to give him three megabit and so forth so those that 23 00:01:47,050 --> 00:01:51,000 try to use are part of the global queue which is the parent. 24 00:01:51,000 --> 00:01:55,900 Q So thats why we call it hierarchical talkin buckets because its just based on you. 25 00:01:55,920 --> 00:01:58,830 So thats what we want to work on the Q3. 26 00:01:58,830 --> 00:02:02,310 Of course we have on the mike Vick also something we call simple. 27 00:02:02,310 --> 00:02:10,200 Q So the difference between the simple Qs and the Q3 is that on the market we have actually they have 28 00:02:10,500 --> 00:02:16,670 somehow similar fashion that they bought or for quality of service but for the simple use it goes into 29 00:02:16,680 --> 00:02:19,590 orders so check first doesnt matter go to science. 30 00:02:19,650 --> 00:02:25,830 Second doesn't much go so far so if you have a cube sitting somewhere in the level of 500 then it has 31 00:02:25,830 --> 00:02:33,210 to go check all the other cues that are available onto the rest of the 500 and that's kinda great for 32 00:02:33,210 --> 00:02:33,820 us DNA. 33 00:02:33,870 --> 00:02:39,030 While on the Q3 is different we create a global queue which is the pattern. 34 00:02:39,090 --> 00:02:40,780 And then we create the chart. 35 00:02:40,770 --> 00:02:47,700 Q So thats mostly differences between both rather as Version 6 which is now the latest version has only 36 00:02:47,700 --> 00:02:52,320 one actually be global and the other version they have to buy now because we are working on the version 37 00:02:52,320 --> 00:02:52,860 6. 38 00:02:52,860 --> 00:02:55,550 Then we have only one issue to the global. 39 00:02:55,770 --> 00:03:00,780 So now we know at a global the about the HDD so let's see now how this should works exactly. 40 00:03:01,080 --> 00:03:04,500 So who needs to have at least one child too. 41 00:03:04,710 --> 00:03:09,750 So if you read the first Q Which is different than if you want to call it Farrand then it needs to have 42 00:03:09,750 --> 00:03:12,310 at least one child under a it. 43 00:03:12,370 --> 00:03:16,980 You get a limit at traffic first then the rest will be decided by the public. 44 00:03:17,040 --> 00:03:18,260 What does it mean. 45 00:03:18,270 --> 00:03:20,070 Lets say we have this example here. 46 00:03:20,100 --> 00:03:25,170 We come here and we create the first bill which they all download and that's the part I gave for this 47 00:03:26,180 --> 00:03:27,810 8 megabit just as an example. 48 00:03:27,870 --> 00:03:32,860 Eight McGavick per site that I created those you can she is the panel. 49 00:03:33,120 --> 00:03:34,860 And then those are the child. 50 00:03:34,860 --> 00:03:42,250 So that is child and this child that is a q which is a balance for those two. 51 00:03:42,390 --> 00:03:44,240 So for this one and for this one. 52 00:03:44,340 --> 00:03:49,420 Those are the type of disparity but this one is child 4. 53 00:03:49,430 --> 00:03:58,460 Q Okay so what I can do here I can say I want to 8 megabit global thats what we call the the maximum. 54 00:03:58,470 --> 00:04:00,350 And that's something we can see at any moment. 55 00:04:00,390 --> 00:04:07,290 The maximum limit so that's the maximum limit of Banku is gonna be 8 McKevitt. 56 00:04:07,350 --> 00:04:08,080 Okay. 57 00:04:08,370 --> 00:04:14,370 And this will be you read as following on this search Hi-Q I would say well I want the limit at the 58 00:04:14,370 --> 00:04:15,730 minimum they got. 59 00:04:15,730 --> 00:04:21,840 As for example one megabit per second and the maximum limit they can go to to make of it. 60 00:04:21,840 --> 00:04:27,320 So they got a minimum of one megabit per second and they can go up to get it. 61 00:04:27,540 --> 00:04:33,300 And here I can define for example to buy to do minimum and maximum. 62 00:04:33,480 --> 00:04:38,260 And here those child will be shared the which is here. 63 00:04:38,670 --> 00:04:39,260 OK. 64 00:04:39,300 --> 00:04:44,730 Now there is the whole idea and then that means that whatever it happens on those you they will not 65 00:04:44,790 --> 00:04:50,270 all exceed the 8 megabit which is the maximum limit which is available on the patent. 66 00:04:50,280 --> 00:04:52,880 Q Okay on thats the global one. 67 00:04:53,160 --> 00:04:54,150 So thats the idea. 68 00:04:54,150 --> 00:04:57,960 How would the use of heisted be work so great the balance. 69 00:04:57,960 --> 00:04:59,580 Q You grade the you. 70 00:04:59,820 --> 00:05:03,750 And then this way you can say what is the minimum What is the maximum. 71 00:05:03,750 --> 00:05:08,420 And that's something I'm going to just got to do with now about the minimum and maximum. 72 00:05:08,580 --> 00:05:15,420 So as I said the to be has to rate limit it has the C R which is Dimmick and the M-I which is the maximum 73 00:05:16,290 --> 00:05:16,810 limit. 74 00:05:17,030 --> 00:05:20,030 So the Army's got that information right. 75 00:05:20,070 --> 00:05:21,180 That means that's the limit. 76 00:05:21,240 --> 00:05:22,650 That's the minimum he can get. 77 00:05:22,650 --> 00:05:26,660 So that means that for example in our case we said that this guy here. 78 00:05:26,820 --> 00:05:32,490 This skew here he would get a minimum one megabit per second that's the CIA are this committed information 79 00:05:32,550 --> 00:05:34,030 that they on the. 80 00:05:34,020 --> 00:05:36,100 The other is known as limit. 81 00:05:36,600 --> 00:05:42,960 They are my arm which is the maximum information rate that Mr. incased all the John Hughes they have 82 00:05:42,960 --> 00:05:48,340 reached the limit at the shot and there is still band was available in the patent. 83 00:05:48,350 --> 00:05:53,210 Q then it will be distributed for the Chuy's to use. 84 00:05:53,400 --> 00:05:58,530 So thats what we call them my arm my arm is the maximum limit so that means if there is some band was 85 00:05:58,530 --> 00:06:04,530 left and they all the time the cues is to have reached there are there still some who was last on the 86 00:06:04,530 --> 00:06:09,480 panel knew that this battle will be shared to the Chinese use. 87 00:06:10,050 --> 00:06:11,740 And thats what it says here. 88 00:06:12,030 --> 00:06:16,320 The first day actually be with right to satisfy each new limit. 89 00:06:16,390 --> 00:06:21,110 So first it will try to satisfy the parent who every child. 90 00:06:21,120 --> 00:06:26,680 Q Which has CAIR and that and Geshe the rest of the bat is there. 91 00:06:26,680 --> 00:06:29,030 That it will be shared to the shots. 92 00:06:29,070 --> 00:06:34,100 That means if there is some Bandler's more than it would go to the MRI of the child's cues. 93 00:06:34,280 --> 00:06:34,780 OK. 94 00:06:34,980 --> 00:06:41,430 So there is no more bandages available and that all the limit of our bathmat then there is no on my 95 00:06:41,430 --> 00:06:47,060 arm so that means that only the child's cues will get the Zayas. 96 00:06:47,160 --> 00:06:54,330 Now there are some here regulation to say why do you want to create the cues on TV. 97 00:06:54,420 --> 00:07:02,070 First thing the am I out of the parent that means this one here the maximum is a measure of the parent 98 00:07:02,070 --> 00:07:11,010 should be greater or equal to the sum of the art of the child again the maximum limit of the body. 99 00:07:11,020 --> 00:07:16,230 That means normally on the ballot you have to put on the maximum show the maximum limit of the ballot. 100 00:07:16,240 --> 00:07:25,130 If you have eight megabits that's the maximum for the part the that this 8 megabit should be equal or 101 00:07:25,130 --> 00:07:30,500 greater than the limit of the charge which is the hour of the child. 102 00:07:30,500 --> 00:07:36,810 That means its child will get the minimum Babbitts and that's minimum balance that we have to look at 103 00:07:36,840 --> 00:07:37,660 for the child. 104 00:07:37,820 --> 00:07:43,290 Some of them should not exceed the maximum limit that is on the planet. 105 00:07:43,370 --> 00:07:46,640 That's first thing to always take it into consideration. 106 00:07:46,640 --> 00:07:51,710 Now the same thing that to take into consideration that the maximum limit of the parents which is like 107 00:07:51,710 --> 00:07:55,110 we said 8 it should not be less. 108 00:07:55,120 --> 00:08:00,560 So it should be always more or equal to the MVR of the child. 109 00:08:00,560 --> 00:08:08,000 So if you want here for example you said if you go back to this example you said you have an hour on 110 00:08:08,000 --> 00:08:12,690 the patent eight that means you had the heart of the child should not go more than 8 megabit. 111 00:08:12,710 --> 00:08:14,780 So that's the am I on the maximum. 112 00:08:14,780 --> 00:08:18,680 And also Same here should not exceed more than 8 megabits and same here. 113 00:08:18,890 --> 00:08:19,350 OK. 114 00:08:19,430 --> 00:08:26,720 So that means that they are out of the balance should always always always be also greater or it will 115 00:08:26,960 --> 00:08:29,600 to the mjr of the child. 116 00:08:29,610 --> 00:08:30,040 Am I out. 117 00:08:30,050 --> 00:08:31,210 And that's our OK. 118 00:08:31,370 --> 00:08:38,600 So if we make it a summary of the parents should be greater than the sum of this and the amount of the 119 00:08:38,600 --> 00:08:44,300 parent should be equal or greater than the amount out of each of the child. 120 00:08:44,360 --> 00:08:49,180 And the last month now is about the issue of the prior Do you have some priority on there should be 121 00:08:49,190 --> 00:08:52,750 that you can use in order to quiet the last traffic on other traffic. 122 00:08:52,850 --> 00:08:53,380 OK. 123 00:08:53,600 --> 00:08:55,880 So the priority was on the child. 124 00:08:55,940 --> 00:09:02,500 So first you need to assign those autopilot to the child cues to cues which are under the parent. 125 00:09:03,410 --> 00:09:09,440 The trash of the priority is from 1 to eight where one is the highest an 8 is the lowest That means 126 00:09:09,440 --> 00:09:16,640 if you want to give priority for the traffic of for example this child Q here then you give it one if 127 00:09:16,640 --> 00:09:20,620 you want to give priority class then you give this three. 128 00:09:20,620 --> 00:09:24,770 And if you want this want to be the last one then you give it for example summer. 129 00:09:24,950 --> 00:09:28,000 So one is more than three three is more than seven. 130 00:09:28,200 --> 00:09:28,730 OK. 131 00:09:28,810 --> 00:09:33,820 The Q With higher parity will get the maximum before the other kids. 132 00:09:33,830 --> 00:09:34,210 OK. 133 00:09:34,310 --> 00:09:40,700 So again the first thing that the parent would do is to meet the limit at this hour for all the cues. 134 00:09:40,730 --> 00:09:47,070 So watch this art is given to all the child cues and there is still band was available then this event 135 00:09:47,130 --> 00:09:50,210 needs to be giving to the child to you in there. 136 00:09:50,230 --> 00:09:56,960 And my God and this man with the bat if you want to give it to the child he will look for the priority 137 00:09:57,290 --> 00:09:58,740 if there is any of the child. 138 00:09:58,750 --> 00:10:04,330 Q Having play the higher than the other then he will give the bad for that one more than the others. 139 00:10:04,550 --> 00:10:06,440 OK so that's the whole idea. 140 00:10:06,500 --> 00:10:10,960 And now I'm going to do an example to show you how they play out the wall. 141 00:10:10,970 --> 00:10:17,090 So I hope now that you understand that the idea of the priority is very straightforward you have priority 142 00:10:17,090 --> 00:10:18,250 from one to eight. 143 00:10:18,290 --> 00:10:23,630 One is the higher rate is the lowest and you if you have the cues and you have a partner and child the 144 00:10:23,630 --> 00:10:29,280 first thing the parents can do is to give the limit at which is desire for the child. 145 00:10:29,300 --> 00:10:35,780 So once it is met and all child now they have these are then there are still boundaries on the part 146 00:10:35,780 --> 00:10:43,430 of the queue then the PACU has to distribute it to the child based on the maximum and based on the priorities 147 00:10:43,450 --> 00:10:46,460 so we will look for the priority which one has the highest priority. 148 00:10:46,480 --> 00:10:52,530 If we get more maxed them out which is I want to get more of them than the other child. 149 00:10:52,580 --> 00:10:55,170 Now let's go and do the examples too. 150 00:10:55,190 --> 00:10:59,650 So you can understand more how the product on TV works. 151 00:10:59,670 --> 00:11:03,130 Example Number one you have first heard about you. 152 00:11:03,170 --> 00:11:09,360 It has maxed them and then we give it again the the you always you have to assigned balance on the maximum. 153 00:11:09,500 --> 00:11:09,960 OK. 154 00:11:10,100 --> 00:11:20,620 So it has timing of it that you see here are six and the maximum is so hour six and my hour is 10. 155 00:11:21,110 --> 00:11:26,960 And here under this panel Hugh they have created a few here which is Spanish for the cube. 156 00:11:26,960 --> 00:11:30,450 Number four on number five which has limit of four. 157 00:11:30,470 --> 00:11:32,460 And much of fun. 158 00:11:32,720 --> 00:11:38,970 And here this one has a limit of two matches often and this one has a limit of two max of that. 159 00:11:39,260 --> 00:11:41,630 Then we can see here this one has product of one. 160 00:11:41,630 --> 00:11:43,350 This one has player of three. 161 00:11:43,370 --> 00:11:45,650 This one has by all three of five. 162 00:11:45,650 --> 00:11:53,600 The question is how much Bankwest will get each of the cues cues three four to five. 163 00:11:53,600 --> 00:11:58,000 So let's set what we have understood now from the last slide. 164 00:11:58,070 --> 00:11:59,540 Let's now try to apply. 165 00:11:59,720 --> 00:12:01,920 We said that first the bottom. 166 00:12:01,930 --> 00:12:11,390 Q We'll try to give the limit for all the cues the child's cues OK but besides that let's just check 167 00:12:11,390 --> 00:12:14,520 they're saying that the part of the cue for Q3. 168 00:12:14,900 --> 00:12:22,280 So that excuse me here the part of the cue for this Q One which is this one and in Q4 and you find the 169 00:12:22,280 --> 00:12:24,110 PACU for Q2. 170 00:12:24,590 --> 00:12:27,640 And of course you want is the path Q of Q. 171 00:12:27,950 --> 00:12:30,050 Now let's see how it works. 172 00:12:30,050 --> 00:12:35,280 First we said that the path you will try to give the limit for each of the cues. 173 00:12:35,450 --> 00:12:47,900 So cute 3 you say the limit is six so that you will give him six and give it OK that you have total 174 00:12:47,940 --> 00:12:51,290 done then what is left is for him to give it. 175 00:12:51,470 --> 00:12:52,360 OK. 176 00:12:52,910 --> 00:12:54,670 That comes to here. 177 00:12:55,660 --> 00:13:02,860 That this one the cue to say that I have formic acid at that then he would give him for that that means 178 00:13:02,860 --> 00:13:05,810 he has no more bandwidth left the if you want. 179 00:13:05,980 --> 00:13:06,620 OK. 180 00:13:07,320 --> 00:13:12,080 Then at times he had four rows are asking I want limit at 2. 181 00:13:12,100 --> 00:13:19,480 So he has four minus two then he has still two and he give this one also limit that to then he has to 182 00:13:19,480 --> 00:13:26,640 then he has then zero so at the end what we have this one which has he received 6 because he has six 183 00:13:26,760 --> 00:13:28,380 megabit as the. 184 00:13:28,630 --> 00:13:34,910 This one has received do so because he has them at two and this one has received two because his it 185 00:13:35,250 --> 00:13:39,850 is true that idea and three should get six and get it. 186 00:13:39,880 --> 00:13:46,700 Q Four should get to me a bid and Q Five should get five and give it and you can see that the bandit 187 00:13:46,740 --> 00:13:48,820 on Q One is finished. 188 00:13:49,040 --> 00:13:49,910 Then we get it. 189 00:13:49,930 --> 00:13:53,800 It has to be distributed based on the limit on the CIA. 190 00:13:54,070 --> 00:13:54,800 OK. 191 00:13:55,060 --> 00:13:57,900 So this is the first example here. 192 00:13:58,000 --> 00:14:04,780 The pratty didn't play a lot of fraud because it is working only on the say on the limit that let's 193 00:14:04,780 --> 00:14:06,900 look now for the second example. 194 00:14:06,940 --> 00:14:11,960 Example Number two we still have essentially you bet now the bandwidth has been changed and that the 195 00:14:11,970 --> 00:14:12,880 key was let's see. 196 00:14:12,970 --> 00:14:14,390 This one has them again. 197 00:14:14,920 --> 00:14:17,870 And the first they want to meet the limit. 198 00:14:17,920 --> 00:14:18,390 OK. 199 00:14:18,580 --> 00:14:20,290 So this one will take two megabit. 200 00:14:20,290 --> 00:14:21,530 That's his limit. 201 00:14:22,390 --> 00:14:24,370 This one would take to make a bet. 202 00:14:24,400 --> 00:14:25,540 That's his limit. 203 00:14:25,750 --> 00:14:28,710 And this one takes to make a bet that's his limit. 204 00:14:29,020 --> 00:14:32,530 So that means that from the Dan the six were gone. 205 00:14:32,530 --> 00:14:36,340 So there is still four left former Gebiet left on the bottom here. 206 00:14:36,660 --> 00:14:38,650 Now we will check for the priority. 207 00:14:38,860 --> 00:14:41,500 Which one has the higher priority. 208 00:14:41,950 --> 00:14:43,500 This one has probably three. 209 00:14:43,540 --> 00:14:46,980 This one has won the spot as 4:55. 210 00:14:47,320 --> 00:14:53,230 We said that the one who has the higher priority is the one who get more bad news than in this case. 211 00:14:53,250 --> 00:14:56,110 Those for me megabit that are left here. 212 00:14:56,170 --> 00:15:03,120 He will send them to you then this cue has in total two plus four or six of it. 213 00:15:03,280 --> 00:15:04,930 This one has plus four. 214 00:15:05,320 --> 00:15:06,360 And that is the result. 215 00:15:06,420 --> 00:15:09,470 Fuselli is getting to make of it which is correct. 216 00:15:09,580 --> 00:15:13,640 Q4 we get six McGavick which is correct and q 5 will get to me. 217 00:15:13,660 --> 00:15:14,780 It was just going. 218 00:15:15,100 --> 00:15:24,570 So you can see now with a priority that the AQ four has received more max limit than the other accused 219 00:15:24,570 --> 00:15:27,000 because he has the product of one. 220 00:15:27,310 --> 00:15:28,000 Let's continue. 221 00:15:28,000 --> 00:15:29,450 For example number three. 222 00:15:29,470 --> 00:15:35,110 Now let's see this example example numbers we would have max limit that on the part of Q And then first 223 00:15:35,110 --> 00:15:41,320 you want to meet the child's AK delimit out of the chart you will get from that then to to this one 224 00:15:41,500 --> 00:15:44,470 because this one has a limit of two. 225 00:15:44,590 --> 00:15:46,540 Then this one has a limit that of eight. 226 00:15:46,540 --> 00:15:52,710 So we give him a plus two that stand that means he doesn't have anything anymore left zero. 227 00:15:53,540 --> 00:16:00,200 That this part of you of those cues you would give them that also they would give to this one and he 228 00:16:00,200 --> 00:16:05,130 would give to this one two plus two for so eight minus four equals four. 229 00:16:05,130 --> 00:16:08,650 Then he has left your form and give it in his view. 230 00:16:08,660 --> 00:16:12,230 Now he needs to give the list to his child. 231 00:16:12,460 --> 00:16:16,030 You would check which one has the higher priority. 232 00:16:16,070 --> 00:16:18,290 This one has three. 233 00:16:18,290 --> 00:16:20,300 This one has five the. 234 00:16:20,330 --> 00:16:27,510 Then it will say OK those four megabit I will give them to this one then this one will and last four 235 00:16:27,730 --> 00:16:29,430 he will end by six. 236 00:16:29,780 --> 00:16:38,410 So it should be six on this one this one two and this one to check to number three to number four six. 237 00:16:38,540 --> 00:16:41,380 And number five is do. 238 00:16:41,480 --> 00:16:44,370 So even though that this one has plenty of one. 239 00:16:44,870 --> 00:16:50,390 But it's not the problem because the idiot like you that we called it has received limit that of eight 240 00:16:50,730 --> 00:16:53,040 and that he will distribute it to his child. 241 00:16:53,090 --> 00:16:53,510 OK. 242 00:16:53,540 --> 00:16:55,870 Because he's part of you for five. 243 00:16:55,880 --> 00:17:00,170 Now the last example that I want to show here is example number four. 244 00:17:00,560 --> 00:17:07,350 So if you look here what we have we have 10 megabits as maximum on this cue that we have here. 245 00:17:07,370 --> 00:17:09,880 This one is limit at six. 246 00:17:09,920 --> 00:17:16,170 This one limit at two and this one limit at 12. 247 00:17:16,400 --> 00:17:20,990 So 6 plus 2 8 plus 12 is 20. 248 00:17:20,990 --> 00:17:26,870 So 20 megabits is limit that why the Macksville limit is 10 megabit. 249 00:17:26,900 --> 00:17:33,360 So how come it's not possible that an interface give more bandwidth than what it has we have maximums 250 00:17:33,670 --> 00:17:40,790 for the global cube if you give it and the limit is asking for 20. 251 00:17:40,830 --> 00:17:54,180 So what will happen in this case because 20 is twice the gain 20 equal than minus two times to correct. 252 00:17:54,360 --> 00:17:59,130 So and in this case what did they get and say Are they sure got half of it. 253 00:17:59,190 --> 00:18:02,290 The bible to meet the master. 254 00:18:02,580 --> 00:18:07,220 So if this one get limit of six and this one get limit of two. 255 00:18:07,530 --> 00:18:08,330 That's eight. 256 00:18:08,700 --> 00:18:12,950 And this one gets limit of 12. 257 00:18:13,170 --> 00:18:16,070 Then in this case then we get half of that. 258 00:18:16,070 --> 00:18:21,570 So this one should get three which is half of six the Trump should get one which is half of two. 259 00:18:21,570 --> 00:18:25,130 This one should get six which is half of 12. 260 00:18:25,290 --> 00:18:27,820 So you can see this one Chad is getting three. 261 00:18:27,820 --> 00:18:34,890 This one is one and this one of six because the rule is that some of these are of the limit and should 262 00:18:34,890 --> 00:18:39,000 not exceed the babbelas of the bank which is timing make of it. 263 00:18:39,210 --> 00:18:44,650 But when you have such a case that what will happen and the mechanics of the reactive the divide the 264 00:18:45,010 --> 00:18:45,920 are available. 265 00:18:45,960 --> 00:18:49,750 In this case by two and then he will give for each of the dice. 266 00:18:49,790 --> 00:18:53,400 Q half of the by the way is which is on the limit. 267 00:18:53,400 --> 00:18:56,750 So with this example I have reached the end of this lecture. 268 00:18:56,790 --> 00:19:02,290 So this lecture was talking about the STV What is the be or how it works and how to use it. 269 00:19:02,400 --> 00:19:07,680 And then we have seen the cues and we see that we have the panel you and the Chuckie's and we have seen 270 00:19:07,680 --> 00:19:09,850 some regulation that we should math. 271 00:19:09,920 --> 00:19:11,450 We want to grade those cues. 272 00:19:11,730 --> 00:19:17,570 And then we also talk about the priority and I give an example about how the product are right is a 273 00:19:17,580 --> 00:19:23,360 very very important topic especially for those who want to do the at the CDC exam. 274 00:19:23,400 --> 00:19:30,150 So please if you don't understand the first and try to repeat this lecture to be able to understand 275 00:19:30,150 --> 00:19:32,700 more how the play of the work on the cues. 276 00:19:32,700 --> 00:19:34,770 So this is what I wanted to show in this election. 277 00:19:34,890 --> 00:19:41,490 I hope that you enjoyed it and that in that section I have to do a lot about how to use the HDD and 278 00:19:41,490 --> 00:19:42,640 the mike because. 279 00:19:42,810 --> 00:19:45,030 So let's go now directly to the next.
