Advantages of Software Defined Networking
Software Defined Networking (SDN) is part of a bigger technology of Software Defined Everything (SDx) which is offered by organization such as VOX Network Solutions and makes services and devices more dependent on the software than the hardware in that they are defined by the software, where a software upgrade means an advancement of the device and inclusion of features that were not available. The aim of SDN is to centralize and simplify the control of the management of enterprise networks which brings along the following benefits.
The first benefit is the provision of a centralized network which make it easier for to provision and manage enterprise network with an example being the increasing cases of making VLANs part of physical LANs, which bring about a knot of dependencies and links. While abstracting data planes and controls, SDN can speed up service delivery and provide flexibility in the provision of physical and virtual network devices from a single location.
The second benefit that SDN reduces the costs due to operations since there are better virtualization control techniques, improved utilization of the servers and more efficiency in administration. Due to the young age of the technology, the results of these cost reductions may not be seen immediately but it is a guarantee that they will come about, because the automation and centralization of routine network administration issues will bring down the cost of operation.
The other advantage is that there is a holistic enterprise management put in place by SDN, whereby enterprise networks are required to set up virtual machines and applications when demanded so as to accommodate new and upcoming processes, such as big data processes, allowing the IT professionals take this tests without affecting the efficiency of the network. 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.
