Search engine for touristic excursions to any place in the world SD WAN (Software Defined Wide Area Network) allows you to connect multiple companies to multiple interfaces while on an SD WAN capable firewall. The SD WAN firewall is application aware and automatically steers traffic over different service providers depending on certain conditions.
As an example you may connect an MPLS network on one WAN connection and repair online for the second WAN connection. With SD WAN the traffic would then dynamically route over either connection according to policies you define.
Overview
To understand how SD WAN works and the way it benefits your organization it is very important first understand how things were configured previously.
Consider cold and hot taps while on an old fashioned wash hand basin. Think of the hot tap (WAN 1 Interface) is connected to the MPLS Network and the cold tap (WAN 2 Interface) is coupled to the Internet.
When the hot tap and cold taps are operated separately it is difficult to regulate the temperature and flow of the water since they are totally separate from the other person. Similarly, ahead of SD WAN it turned out challenging to mix, control and manage traffic (business applications) across separate independent WAN Interfaces (with this example MPLS and Internet) just like the water in an old wash hand basin.
Exactly why is SD WAN better?
SD WAN is quite as being a modern wash hand basin with the recent and cold taps combined in an very easy to adjust mixer tap. The temperature of the water might be controlled and can even be automatically regulated to offer you the perfect hot and cold levels always.
With SD WAN you can have granular treatments for traffic across all WAN networks with advanced flexibility and agility. For example, you can define policies that frequently send traffic out of your main business application in the MPLS network by way of example but automatically switch over to the net VPN when the MPLS network is congested or unavailable.
SD WAN transfers the load of traffic management from physical devices to software and permits you to effectively and securely route website visitors to remote locations including branch offices. Centralised control gives full visibility across the network and enables simple management.
In conclusion SD WAN gives you complete control over the way you dynamically route and prioritise traffic according to application type and other factors for example congestion and availability.
Just how do SD WAN benefit your organization?
Lower bandwidth costs
Centralised network management
Full network visibility
Increased choices for vendor selection and connection type
SD-WAN benefits businesses by removing expensive routing hardware and instead provisioning connectivity and services from the cloud. With the increased addiction to cloud-based services in the current workplace SD WAN offers a far more robust and reliable network.
SD WAN can be a far more flexible option which allows an enterprise to scale connectivity around as their business dictates and may automatically adjust and steer cloud-based traffic over different routes when congestion or vendor failure occurs. This enables a company to operate a lot more efficient and cost-effective enterprise reducing bandwidth costs as needed without compromising availability. Companies are effectively avoiding over provisioning which lowers overall WAN costs.
The centralised control enables changes to become implemented and quickly pushed over to network hardware including routers and switches.
After a preliminary investment SD-WAN can improve a business’s connectivity between branch locations, the primary office, data centres along with the cloud while reducing running costs making lasting savings over time.
