sd-wanWhat is SD-WAN?

Software-Defined Wide Area Networking (SD-WAN) is a transformational approach to simplify branch office networking and assure optimal application performance. Unlike traditional WANs, SD-WAN delivers increased network agility and cost reduction. SD-WAN has its roots in Software-Defined Networking (SDN), the underlying principle of which is to abstract the network hardware and transport characteristics from the applications that use the network.

Are you looking to:

  • Improve application performance, particularly for cloud apps?
  • Increase bandwidth at remote or international sites?
  • Replace an expensive private network?
  • Simplify or outsource the management of your network?
  • Build resiliency into your network to guarantee uptime?
  • Decrease turn-up time for new sites?

SD-WAN is changing the way IT departments think about networking multiple locations. As an appliance-based solution, it provides a simpler, smarter, more resilient WAN—leveraging various types of connectivity. Think of it as the “WAZE” of WAN architecture—”outsmarting traffic, together”. SD-WAN measures quality and optimizes traffic.

What is SD-WAN?
SD-WAN is a combination of technologies designed to offer a simpler approach to the WAN. It’s being driven largely by the decreasing cost of bandwidth and the increase in cloud applications that reside outside of the legacy data center. It can be deployed over existing WAN connections, whether they are Internet (DIA, broadband, LTE) or private (MPLS, private line), in order to create a secure, private, fully meshed network. It offers simplified management, quicker turn-up, better application performance, improved resiliency, and cost savings when compared to traditional approaches.

Key Drivers:

  • Cloud Applications
  • Cost Savings
  • Simplified Management
  • Performance
  • Time-to-Deploy

As applications continue to move to the cloud, networking professionals are quickly realizing that traditional WANs were never architected for a dynamic, Internet-based environment. Backhauling traffic from the branch to headquarters to the internet and back again doesn’t make sense. Employees sometimes even find their business apps run faster at home or on their mobile devices than at the office.

SD-WAN provides a more consistent, high-quality experience across distributed locations while reducing IT costs and management complexity.
