In the previous topic, we have studied the votes of the communication architecture, which is an operating
system for you, execute applications and control half of it.
Now, in this topic, you are going to learn about software defined networking.
That is, as did the AZN, a technology approach to network management.
That enable dynamic, programmatically efficient network configuration in order to improve macro performance
and monitoring by making it more like cloud computing than traditional management.
Moreover, there's the permit, which is to run a simple program which can change forwarding rules,
modify a packet or drop it to to this program.
Hoopers, which isn't noticed.
For example, using the as end, we can pull down the switches and halters remotely.
So that is statistically YAZJI and it will be more clear to help the following diagram.
So the software defined networks consist of three layers, that is infrastructure layers controller
and third one is the application layer.
So the infrastructure layer referred to as an actual network hardware that consists of four network
routers, switches, base stations, etc. It enables the open standard based access to infrastructure
to enable programming from Asgeir Controller.
So it support a two way communication with the help of as did controller.
The next layer is the controller that as the controller construct and present the logical map of the
network for efficient decision making by its design applications that are sitting inside the application
layer.
Well, the application layer communicates with SD and controller using API in their application programming
interface using API, where the developers can write their applications for different different aspects
and they do not have to worry about the details of our learning network.
So using different API, different application, such as a business application or committed configuration,
everything can be designed using different kind of API so that as you needed an interesting concept
which is used to manage a huge network and it can be distributed in three parts.
Infrastructure, layer, control, different application layer.
In this topic, we have learned about the software defined radio, and in the next topic, we are going
to learn the communication standard.
