WEBVTT 1 00:00.000 --> 00:03.920 Well, as we mentioned in the intro, we are going to end every skill with a 2 00:03.920 --> 00:04.360 challenge. 3 00:04.360 --> 00:07.680 And this challenge is one that doesn't have a solid answer. 4 00:07.680 --> 00:11.260 It's going to depend a little bit more on your organization and the network 5 00:11.260 --> 00:11.560 that you're 6 00:11.560 --> 00:13.080 used to supporting. 7 00:13.080 --> 00:17.250 So I highly recommend taking the time to look at your network architecture and 8 00:17.250 --> 00:17.600 see how 9 00:17.600 --> 00:20.720 well it maps back to the hierarchical network model. 10 00:20.720 --> 00:25.010 Now you might find that there are a lot of exceptions to where it doesn't quite 11 00:25.010 --> 00:25.920 fit perfectly 12 00:25.920 --> 00:27.160 with the model. 13 00:27.160 --> 00:31.280 You might have, for example, data center servers that are hanging off of your WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000 13 00:27.160 --> 00:31.280 You might have, for example, data center servers that are hanging off of your 14 00:31.280 --> 00:32.160 distributions 15 00:32.160 --> 00:34.920 which at your headquarters location. 16 00:34.920 --> 00:36.880 And there can be good reasons for that. 17 00:36.880 --> 00:39.240 It could have been a mistake potentially. 18 00:39.240 --> 00:43.710 But ultimately, what we're going to find is that the more we can stick to this 19 00:43.710 --> 00:43.840 model, 20 00:43.840 --> 00:48.500 the more scalable and more redundant and more resilient and robust, just to 21 00:48.500 --> 00:49.160 toss more 22 00:49.160 --> 00:52.480 words out there, that our networks are going to be. 23 00:52.480 --> 00:56.810 But that said, as network architects and as network designers, as we try to put 24 00:56.810 --> 00:57.240 ourselves 25 00:57.240 --> 01:02.440 in that frame of mind, we are also going to find that the world is not perfect. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000 25 00:57.240 --> 01:02.440 in that frame of mind, we are also going to find that the world is not perfect. 26 01:02.440 --> 01:06.920 And especially as it relates to trying to map to the hierarchical network model 27 01:06.920 --> 01:07.320 , yes, the 28 01:07.320 --> 01:10.000 more we can do it, the better off will be. 29 01:10.000 --> 01:11.600 But there are going to be exceptions. 30 01:11.600 --> 01:15.380 There are going to be reasons some of which might just be budget reasons that, 31 01:15.380 --> 01:15.720 hey, we 32 01:15.720 --> 01:22.630 could physically do the exact model or we could save a bunch of money by taking 33 01:22.630 --> 01:23.560 shortcuts 34 01:23.560 --> 01:27.240 or otherwise doing some things we wouldn't normally recommend. 35 01:27.240 --> 01:30.870 And so our job as network engineers and as network architects, if we step into WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000 35 01:27.240 --> 01:30.870 And so our job as network engineers and as network architects, if we step into 36 01:30.870 --> 01:31.560 that role 37 01:31.560 --> 01:37.080 or are in that role already, is to do our due diligence, make sure we're trying 38 01:37.080 --> 01:39.080 to apply 39 01:39.080 --> 01:44.600 the results of our network designs and our network installs, map that back to 40 01:44.600 --> 01:45.400 this model 41 01:45.400 --> 01:50.060 as best we can because the organization is going to be the one that benefits 42 01:50.060 --> 01:50.960 the most. 43 01:50.960 --> 01:54.300 Because our networks are going to be online, they're going to be available and 44 01:54.300 --> 01:54.760 we're going 45 01:54.760 --> 01:59.280 to be able to avoid any nasty situations in the future. 46 01:59.280 --> 02:03.960 We didn't anticipate we're coming because we've built out our scalable network. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000 46 01:59.280 --> 02:03.960 We didn't anticipate we're coming because we've built out our scalable network. 47 02:03.960 --> 02:06.680 I hope this has been informative for you and I'd like to thank you for viewing.
