Benefits of Software Defined Networking
Software Defined Networking (SDN) is a component of Software Defined Everything (SDx), a technology that moves devices from being defined by their hardware to their software, meaning that an upgrade of the software would mean a more enhanced device. SDN is available to allow for simpler and more centralized control of the enterprise network management and has the following pros.
To start with, SDN give life centralized network provisioning which enhances the central view of the whole network , however big it is, which makes it easier to provision and manage the enterprise, with example being the transition of VLANs to being part of local LANs, which create dependencies and Gordian knots. There is more agility in the provision of the physical and virtual networking devices from a single location when data planes and controls are abstracted making SDN speed up delivery.
Secondly, there is lower operating costs due to the advancement of server utilization, more efficient administration, improved control of virtual processes. Although these benefits may not have been experienced, based on other benefits that come along due to SDN, it is safe to say they will come about because automation and centralization of routine network administration processes will cut down on costs.
Another advantage is that there is a better and holistic enterprise management where SDN allow the IT technicians experiment on using enterprise networks to set up virtual machines and applications that accommodate contemporary request such as big data requests. By creating a set of APIs to manage both the physical and virtual devices, SDN supports the administration of both virtual and physical switches and networking devices from a one central controller.
Moving on, the other advantage is that SDN guarantees the delivery of content due to its ability to shape and regulate data traffic, which enables instruction and automation of data traffic and implementation quality of service that govern multimedia transmissions and voice over IP. With SDN in place, streaming of high quality video over the internet is not a problem, because it improves the user experience by bettering the response speed and quality of the network.
The last benefit is that SDN is useful in cloud abstraction, because it makes it easy and simple to abstract cloud resources using software defined networking which is essential in moving towards the direction of unified infrastructure, which is where cloud is taking us. With this technology, the networking equipment in the global serving data centers can all be managed from one platform, which is the SDN controller.
