A Software-defined Wide Area Network (SD-WAN) is a virtual, software-based WAN architecture. Unlike a traditional WAN that relies on having users connect to applications hosted on a central server, SD-WAN provides an extension to multiple public clouds. This in turn increases application performance while delivering a secure user experience. 


Benefits & Advantages of Software-Defined Wide Area Networks (SD-WAN)


Since SD-WAN is a virtualized network overlay abstracted from hardware, it offers more flexibility than a standard WAN. The benefits and advantages of SD-WAN include:


  • Seamless Application Experiences - SD-WANs offer high availability for critical applications and dynamic routing of application traffic.
  • Enhanced Connectivity & Security - Traditional WANs were never designed for the cloud. SD-WANs are designed to support applications on different clouds and deployment model, including SaaS services. 
  • Lower Costs - SD-WANs provide simplication by removing the requirement of having application traffic from branch offices go through servers located in a company's headquarters. Instead, users can acess those same applications in the cloud. 


SD-WAN is designed for the cloud. As of March 2020, the U.S. General Services Administration requires the replacement of time division multiplexing (TDM) networks. Discover how you can ensure your business-critical communications stay connected by migrating to the cloud with Mitel.
