What is SD-WAN?

SD-WAN is Changing the Communication Landscape

SD-WAN technology isn’t new but has become more appealing to businesses that have shifted into the cloud while adopting a more intricate and responsive communication method. Traditional means of a communications network between a central backbone and the individual local networks cause delays and bandwidth requirements.

SD-WAN allows businesses to connect users and systems without conceding to compliance and security mandates. The demand for SD-WAN is growing and according to a recent report, SD-WAN is expected to grow to USD 13.7 billion in 2021 from USD 3.4 billion, a CAGR (compound annual growth rate) of 39.1%.

What is SD-WAN?

Software Defined Wide Area Network, also known as “SD-WAN” is a software defined networking (SDN) approach that elevates network traffic management away from hardware and premises, to next-generation software in the cloud for enhanced agility, control, and visibility.

How does it work?

SD-WAN uses a centralized control function incorporating user defined application and routing policies, to provide highly secure, dynamic, application-aware network traffic management.

This level of control allows for optimal delivery paths across any combination of network transport types, providing flexible deployment options and improved total cost of ownership.
