Software defined networking

Introduction to Software Defined Networking

Why is it important to understand how software defined networking can help us? There are many reasons. With the right tools, it is possible to create very complex networks with low cost, high reliability, high throughput, as well as security. These networks do not involve the use of internet or internal public IP. Instead, they make use of software and service oriented architectures. This means they are flexible in the sense that they can be used for both private and public networks.

I want to discuss one software defined networking with an example. Let’s say you are developing a software guided website that provides medical advice. Your web pages are created using a WYSIWYG editor. You are connecting with a server over the internet to deliver content and information to your site’s visitors.

In this software defined networking example,

The first step is to establish a connection to the internet using an inexpensive VoIP enabled telephone system, or a regular telephone for that matter. You have a choice here between a plug-in model, where the connection comes from the internet (a software-defined network) or a point-to-point model where the connection is a dedicated physical connection. If you choose the plug-in model, you would select a company that has implemented SIP trunks and integrated them into its billing system.

Secondly, once you have established a connection to the internet, you would select software defined networking that supports software guided telephone system (PBS) solutions. Your company would then be able to easily integrate voice data with video data in real time, along with web content and other information via the company’s website or applications. The final step would be to develop customized application or software modules that will be used by your employees, clients and other customers. This is where networking comes into play.

the third component of this scenario is where the software is loaded onto a wireless enabled device such as a smart phone or tablet computer. Then, your associates can take this information and share it through a conference or via a web-based portal. If you were a large pharmaceutical corporation, you might want to connect your employees to the company’s main website. This way, you can post new leads, release new products and manage the medical office via an easy to use application interface. In other words, software defined networking allows you to leverage your company’s assets without actually owning or leasing those assets.

The fourth component is where the software defined networking begins. Now that you have your network set up, your associates can interact with each other in real time. This can include text-based communication or audio. As your software program becomes more sophisticated, your ability to create rich interactive experiences will grow as well. You will be able to easily access each other’s files, work together on projects, and collaborate on business. Ultimately, you want to create a network that can meet your unique needs.

The last component is what is referred to as the software defined network architecture. This layer controls the distribution of packets across the various layers. The benefit of using this layer is that it is highly elastic, allowing changes to be made to packet forwarding as they arise without disrupting the rest of the system. It also controls the security of the network and maintains the integrity of the data center.

This technology allows you to easily add on new networks as they become available while maintaining the security and reliability of the existing networks. It is important to understand how networking software defines and deploys the layer in order to get the most out of the technology. In addition, it is critical to determine whether you are comfortable working as a service provider or a server administrator. The former requires training and knowledge of the networking software stack while the latter requires direct management of the servers and their equipment.
