Software Defined Networking (SDN) Market - Global Industry Analysis, Size, Share, Growth, Trends, and Forecast, 2012 - 2018, a report by US based market intelligence firm Transparency Market Research provides some valuable insights about the global SDN market along with forecasts of various factors affecting the growth and decline of this market in various application areas and geographic regions of the world, during the forecast period between 2012 and 2018.
According to the report, the global SDN market could reach a market value worth USD 3.52 billion by 2018, by observing year-on-year growth at CAGR of 61.5% during the forecast period.
Contrary to conventional networks where the flow of data packets is managed by a predefined set of routing rules hardwired in the network switches, SDN technology relies on software algorithms for routing data packets throughout the network. SDN essentially changes the control of data flow in the network from the conventional hardware devices to a software application called controller.
Such settings allow network administrators and engineers to quickly respond to changing data requirements in an enterprise setup. Also, the network administrator can change the routing rules of switches in the network thus allowing prioritization, de-prioritization or even blockage of certain types of packets from the network. It is also possible to shape the flow of traffic in such setups through the central control console, without having to touch individual switches.
SDN technology provides innumerous benefits. Some of these include automation, flexibility and the possibilities to dynamically change the data flow according to changing data needs in a network.
Such facilities are especially beneficial in cloud computing services where a single network is rented by a number of different clients, all of which might have different data needs.
According to the report on the global SDN market by Transparency Market Research, the growth of this market in the future would be primarily driven by the rise in adoption of the cloud computing technology. This is due to its benefits in providing rapid and cost efficient data storage and access along with added flexibility, programmability and manageability in the network.
The report states that there are three major end users of this industry, viz. cloud computing infrastructure, enterprise applications and telecommunications services.
Of these, the enterprise applications' segment is the lead revenue generator, followed by telecommunications services and then the cloud computing segment. It is estimated that the segment of enterprise applications amassed nearly 35% shares of the global SDN market in the year 2012.
