Software defined Networking has been considered as a very strange term for such a long time but for the past years, companies are adapting SDN due to its ability to reduce capex and opex.

But, why is SDN in such a hype? Let’s find

SDN offers:

• Dynamic scalability.
• Central control management.
• Lesser Error-prone manual.
•  Handles heavy traffic.
• Virtualization of the server in the data centers.

Traditional networks did not offer such characteristics and were tightly coupled and expensive. To handle the expensive issues, open source communities gave birth to SDN.

“Software Defined Networking”, this name clearly states that SDN is an implementation of software and is evolving with times.

To better understand the need of SDN, just consider the fact that traditional networks in data centers demanded manual configuration hence they were more vulnerable to errors. Secondly, the reconfiguration process of those networks were even riskier and costly with a lot of errors. The configuration, monitoring and troubleshooting is far more considerate and easy in SDN rather than other conventional networks.

As a beginner a vast concept is enough to make you understand what SDN is? And, that is SDN is nothing but a separation of control plane from data plane. The diagram below will make this concept even more clear.

Traditional networks dealt with only routers and switches.

The separation between planes has many advantages like:

• Central management

You can easily perform a lot of centralized functions like troubleshooting, monitoring and configuration. You can also get a whole view of the network by the help of controllers.

• Light Weight equipment

In order to make equipment like router and switches less expensive, they can be slimmed down and this is done by the control plane that controls underlying network elements like protocols.

• Virtualization of Network

Virtualization is the best way to achieve multi-tenancy which means that a single software architecture will fill up the needs of multi-tenants. SDN is powerful enough to force the admins to administer all the programs virtually. For instance, data centers, a place where virtualization is met and a physical network is shared among a number of customers.

SDN is now deployed by a number of companies and open source communities. It is the future of the 21st century but the problem is that half knowledge is not enough to perform any task well. If you want your enterprise to flourish and dig out some real benefits then move to Logic Finders. Logic Finders can teach you with most appropriate and required knowledge about SDN in a few days. Isn’t it amazing that you will be able to configure SDN in a few days? Also, if you are a job seeker then certification in SDN can take you to the top with the most desired salary job.
