In an age where time is increasingly of the essence, business managers are consistently seeking ways in which they can complete tasks more efficiently and quickly.
For network administrators within a company, the advent of software-defined networking (SDN) makes networks easier to manage through the abstraction of lower-level functionality.
Those who have already implemented SDN are likely to have cited the reduction of opex or the improvement on time to market (possibly both, in some cases) as the reason for doing so. Many businesses are currently weighing up the possibility of adopting SDN, which will make their networks more agile, easier to configure and easier to manage centrally. It will also allow networks to be programmed directly, as they will be decoupled from forwarding functions.
With networks facing an increasing need to be highly flexible, it’s no great surprise that IT managers are turning to SDN. However, it is a concept about which some professionals have raised concerns, including difficulty with scalability, as well as the time and expenditure involved in implementing SDN and customising it to best suit specific requirements.
