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. SDN is available to allow for simpler and more centralized control of the enterprise network management and has the following pros.
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 other benefit is that SDN results to lower operations costs since there is improvements in terms of server utilization, there is a better and centralized control of virtual processes and other advantages that result to more operational costs reduction. 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.
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. SDN creates one set of APIs that enable the management of both physical and virtual devices from one console, making it possible to support the physical and virtual switches from a single location, something that is impossible for the SNMP technology.
The other advantage is that it guarantees content delivery though its ability to automate and direct traffic making it easier to apply quality of service in multimedia and voice over IP transmissions due to its due to the ability to control and shape data traffic. Users can easily stream high quality videos fast because SDN improves the responsiveness of the network
Lastly, SDN allows for cloud abstraction where it makes it easier to abstract cloud resources using a network that is defined by a software, a good roadmap to the unified resources and infrastructure that cloud computing is bringing. With this technology, the networking equipment in the global serving data centers can all be managed from one platform, which is the SDN controller.
