Something that is always true about technology is the fact that it is always in motion, so think about this whenever you are looking for something true about technology. You see that as the world is becoming more and more connected globally, the necessity of technology is becoming more obvious. Technology is affecting both individuals and businesses and one way in which you could see this is the way that networking is taking place. There was a time that there was really a possibility for you to be taking care most of the networking through software defined networking or also known as SDN or
For those who are using SDN, even if it does provide several benefits for them the network that is now being used is the one which is global and not anymore localized. The reason why it is beneficiary for software defined networking to have the extension to the wide area network or WAN is this. This could have the ability to tie more than one local area network together since this is allowing it to span through a bigger geographical area. The wide-area networks are mostly tied together through the public network which includes the telephone system or the cable system. Through satellites or leased lines, it might also have the possibility of tying a WAN together. A WAN that is considered as the largest is the internet.
The fact that software defined network is not allowing much growth in the network is an issue. Those that are local networks are rather rigid in their performance and they do not have the capability of adapting well to change. There is a possibility for you to control the elements of the network and it will be allowing smart decisions to be made in the network if ever you are going to remove existing protocols in this kind of networking and set up a standard of APIs. In opening up the network to more of a global level, this is very helpful.
There could be an issue in the network management that could happen when you implement software defined networking. You can start by moving away from controlling each of the WAN hardware device and program all of them with the central software that would be used as a controller.
It is essential that you take in consideration of the effect that would have on your business prior to implementing any form of networking, despite of whether it is WAN, SDN or a combination of both. The investment is something that you might want to think about and it would really take some time before you could see it. So before starting anything with networking, think about all the possibilities.
