Hello, Welcome back, says Go Certified design associate CCD. A Course license 1.5
I'm an instructor, Willie Unseen
previous video. We introduced the characterizing the existing network.
From this video, we will begin to introduce a designing and networked apology and solutions.
Here's the previous That's my question.
Which design solutions states that the design must to start from the physical layer in the finish in the application layer
A p p d i o
b o s. I am. Although
see hierarchical architecture
the top down
e bottom up.
I'll give you a second to think
it is a bottom up top of bottom represents for application earlier and a physical ear off a ways and model seven layer.
All right, so the answer is bottom up. We're gonna discuss Ian the further off course.
This section describes the top down approach for Never. Dely reviews a pilot and
prototype test the networks, and it describes the confidence over the land documents
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
network designs are cast a they're using a pilot or
prototype networking before moving into the implementation face right. We will compare top down with the bottom up approach as well.
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
with the top down approach. Never. Devices and technologies are not selected until the applications requirements are analyzed
to completed help down the line. The following is accomplished Announces of application and the organization requirements right
The flying requirements for upper layers application layer, presentational layer and session earlier. Right. Specify infrastructure for lure OS I layers Transportacion
Network Datalink of physical is so etcetera. Gather additional data on Lee Network.
Right from these light, you can see the flow chart of the top. They'll design right.
There's a comparison of top down on the bottom of approach.
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
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
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
that's greatly needed analyzed the further specific requirements first
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
tested in an isolated in merriment.
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
well, implementing a new technologies such as I P sec. You might want to implement a prototype test before deployment to the operational network.
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
to the task over the Internet works
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.
There's a learning check. Question number one. What is important for talk down design concept?
A engage of the employees working on the top floors in the building during the design process.
Be engagement all over the top executive is that during the design process,
see engagement? All the top executive is that once the design process is finalized,
the engagement of the H R representatives during the design process
e engagement of the legal department before design process started
give you a second to think.
Okay, here's the answer.
Engagement of its top executives it during the design process.
Let's move on to the next one.
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.
I'll Give You One second, I think.
Okay, here's the answer.
Hopefully, you get this right
in today's brief lecture with disgust, Top down approach, bottom up approach pilot on a prototype tests.
Any questions? Feast on me. You know,
I'll see you in the next video. Bye for now.
