What Is Software-Defined WAN (SD-WAN)?

Traditional wide area network (WAN) connections require proprietary hardware, fixed circuits and expensive setup. But today each and every business needs a scalable, flexible and open cloud-based solution to ensure they can deliver a stellar customer experience from anywhere, at any time.

Software-defined WAN (SD-WAN) is here to provide the WAN connections you need in the way you want.

SD-WAN simply applies software-defined networking (SDN) concepts to WAN connections. SD-WAN uses multiple tunnels to optimize bandwidth by directing WAN traffic along the best routes from and to data centers and offices. This means it helps you manage your WAN traffic in real-time.

Noticeably, SD-WANs can be managed by a centralized controller. Staff can simply configure edge devices, reduce provisioning time, and thus reduce or completely eliminate the need to manually configure traditional routers in branch locations.

Benefits of Deploying SD-WAN
1) Provides you a business-class, secure and cloud-enabled WAN connection and addresses many networking problems such as congestion, jitter and packet loss.
2) Enables you to seamlessly run advanced communication systems and features such as VoIP, video conferencing, streaming media and virtualized applications by reducing latency.
3) Support VPNs, WAN optimization controllers, firewalls and web gateways. This makes your network secure and enhances its reliability.
4) Quality of Service (QoS). As SD-WANs have application level awareness, they can effectively prioritize the applications running in your network. To be exact, they are capable of directing
applications through faster links using dynamic path selection, and routing the application using two paths to make sure the service is smooth.
5) You have greater flexibility, as SD-WAN supports multiple connection types such as MPLS, frame relay and LTE.
6) Help you build higher-end WANs using lower cost and commercially available Internet connections.
7) Network continuity including failover to secondary or Third circuit – while both circuits are active so you are not paying for bandwidth you are not using.
