Hello, Welcome back, says Go Certified design associate CCD. A Course license 1.5
00:08
I'm an instructor, Willie Unseen
00:11
previous video. We introduced the characterizing the existing network.
00:16
From this video, we will begin to introduce a designing and networked apology and solutions.
00:23
Here's the previous That's my question.
00:26
Which design solutions states that the design must to start from the physical layer in the finish in the application layer
00:36
A p p d i o
00:38
b o s. I am. Although
00:41
see hierarchical architecture
00:43
the top down
00:46
e bottom up.
00:49
I'll give you a second to think
00:53
it is a bottom up top of bottom represents for application earlier and a physical ear off a ways and model seven layer.
01:07
All right, so the answer is bottom up. We're gonna discuss Ian the further off course.
01:17
This section describes the top down approach for Never. Dely reviews a pilot and
01:23
prototype test the networks, and it describes the confidence over the land documents
01:29
as part of the design process of the PB and left Psycho. A top down approach is used that the games with the organization's requirements before looking at the technologies
01:41
network designs are cast a they're using a pilot or
01:46
prototype networking before moving into the implementation face right. We will compare top down with the bottom up approach as well.
01:56
Top down design just means is starting your design from the top layer off the oh I said Model, working your way Down Top down designed app to the network and physical infrastructure to the networked applications requirement
02:10
with the top down approach. Never. Devices and technologies are not selected until the applications requirements are analyzed
02:21
to completed help down the line. The following is accomplished Announces of application and the organization requirements right
02:30
The flying requirements for upper layers application layer, presentational layer and session earlier. Right. Specify infrastructure for lure OS I layers Transportacion
02:46
Network Datalink of physical is so etcetera. Gather additional data on Lee Network.
02:53
Right from these light, you can see the flow chart of the top. They'll design right.
03:02
There's a comparison of top down on the bottom of approach.
03:07
Okay, let's start with the bottom up. Approach these approach. It begins with the physical layer off the OS, and Mado works its way up
03:16
New hire van away. The links a man be purchased as well as new rodders, assuages firewalls, et cetera. Designing a network with a bottom up approach enables you to get your network set up a much faster
03:30
top down approach. With this approach, we're going to start with the requirements off the organization. The technology that is needed on the dance design it from the top down. The implication layer is the starting point under the applications, and a service citizen that are
03:47
that's greatly needed analyzed the further specific requirements first
03:54
as soon as the designs A complete before the full implementation. It is a fast practice to cast the new solution right. This testing can be done in one of two ways. Prote, attack or pilot. A prototype network is a subset of the food design
04:13
tested in an isolated in merriment.
04:15
The prototype does not connect to the existing network. It isn't a nun production, a network that benefits of the using. The prototype is that it allows the testing off the never design, but four it is deployed a prior to affecting that protection network
04:31
well, implementing a new technologies such as I P sec. You might want to implement a prototype test before deployment to the operational network.
04:42
Ah, pattern. The site is in an actual production network location that serves as a cast the site before the solution is deployed. It toe all productions in an end. Price right? A padded a loss. Real world problems to be discovered before deploying. A network design solution
05:00
to the task over the Internet works
05:02
with both a prototype on a pirate. Successful testing leads to proving the design and moving forward with the implementation. A fitter leads to correcting the designer, repeating the tests to correct any deficiencies.
05:20
There's a learning check. Question number one. What is important for talk down design concept?
05:27
A engage of the employees working on the top floors in the building during the design process.
05:32
Be engagement all over the top executive is that during the design process,
05:39
see engagement? All the top executive is that once the design process is finalized,
05:45
the engagement of the H R representatives during the design process
05:50
e engagement of the legal department before design process started
05:56
give you a second to think.
06:01
Okay, here's the answer.
06:03
Engagement of its top executives it during the design process.
06:09
Let's move on to the next one.
06:12
Question. Number two which design enables Edie and a flexible skating in the system Enterprise Architecture Model A modular Be top gown, Sea bottom up the full mash e para Half Prototype.
06:28
I'll Give You One second, I think.
06:30
Okay, here's the answer.
06:33
Margarine.
06:35
Hopefully, you get this right
06:40
in today's brief lecture with disgust, Top down approach, bottom up approach pilot on a prototype tests.
06:47
Any questions? Feast on me. You know,
06:51
I'll see you in the next video. Bye for now.
