SD-WAN

WHAT IS DRIVING THE TAKE UP OF SD-WAN?
In a nutshell – cost and flexibility. SD-WAN is replacing high cost fixed circuits by enabling the migration of business networks to low cost Internet access.

SD-WAN technology maintains quality of service by routing private WAN traffic around Internet bottlenecks and failures, and by intelligently assigning available bandwidth based on application or use.

SD-WAN combines several technologies to create fully fledged managed private networks over the Internet, with the ability to dynamically share network bandwidth across connection points.

Traditional WAN

  • Traditional fixed circuit WANs connect places of business to data centers for user access to business applications.

  • Because of their fixed nature, WANs face important operational challenges such as network congestion, packet delay variation, packet loss, and even service outages.

  • Modern applications such as VoIP, videoconferencing, streaming media, and virtualised applications require low latency and an ever-increasing need for more bandwidth.

The New WAN

  • SD-WAN has been designed to solve WAN network problems by enhancing or replacing traditional routers with appliances that use application-level policies to control traffic flows.

  • SD-WAN acts as a private network overlay, allowing less expensive consumer-grade Internet to be treated like a dedicated circuit while maintaining quality-of-service, security, and resilience.

  • SD-WAN consists of:

• The SD-WAN Edge is a physical or virtual network device that is placed at a branch office, data center, or cloud platform
• The SD-WAN Orchestrator is used to define policies for application flows.
• The SD-WAN Controller distributes policies to SD-WAN Edge devices which process application flow traffic based on the availability and performance of available routes to the destination
  • The overall SD-WAN solution ensures that application performance meets required service levels.
