What is SD-WAN? Modern Network Management Explained

The adoption of cloud computing solutions and reliance on decentralized remote workforces have put considerable pressure on conventional network infrastructure. 

Old branch designs usually backhaul all cloud communications through corporate data centers, which results in bandwidth problems, delays, and high costs of maintaining the connections. 

Reading more about what is SD-WAN will help you learn about how the intelligent virtual overlay can route data through multiple connections and increase the efficiency of operations in modern businesses.

What is SD-WAN? 

SD-WAN, or Software Defined WAN, is a kind of virtualized network design that helps organizations to safely connect users with their applications using various transport services such as MPLS, broadband internet, and 5G cellular networks.

Some key operating principles of the system are:

• Control Plane and Data Plane Separation: network management software is separated from physical routers and allows managing policy centrally.
• Dynamic Routing: measures connection quality and routes application traffic over the best path.
• Orchestration: helps to manage all branches from a central console.

Advantages for Enterprise Networking

Some major advantages are provided by an upgrade to traditional corporate infrastructure:

• Cost Savings on Transit: Utilizes low-cost commercial broadband instead of costly dedicated MPLS services.
• Improved Application Efficiency: Offers direct access to the cloud, which improves SaaS application performance without routing through the data center.
• Easier to Manage: Centralized provisioning provides the ability to deliver pre-configured branch routers in minutes via remote deployment.
• Automatically Secured: Secure data transport over all public Internet routes and can be integrated with current cloud security technologies.

Transforming Traditional Enterprise Networking

The introduction of dynamic software management changes everything about how IT functions handle large enterprise networks. Old-school networks are dependent on engineers physically altering individual routers every time there are any changes in the policies. 

A software-based management system handles this automatically and ensures that there is consistency in security policies, QoS priorities, and user access controls throughout all branches.

Enterprise networking transformation means that the company has enough flexibility to grow its digital presence without any problems and use cloud capabilities easily.

Conclusion

Using old-school network systems makes a business inflexible and increases costs significantly. From What is SD-WAN, it is clear how software-based management transforms the world of connections by providing efficient traffic routes and reducing transport costs.
