Overview

Software-Defined Wide Area Network (SD-WAN) applies SDN principles to the WAN. It allows organizations to use a combination of transport services—including MPLS, LTE, and broadband internet—to securely connect users to applications.

Key Features

  • Dynamic Path Selection: Automatically routes traffic over the best available link based on real-time performance metrics.
  • Centralized Management: Configure and monitor all branch office connections from a single dashboard.
  • Zero-Touch Provisioning (ZTP): Simplifies the deployment of new branch offices by automating the initial configuration.
  • Integrated Security: Often includes built-in firewalls and VPN capabilities.

Benefits

  • Cost Savings: Reduces reliance on expensive MPLS circuits.
  • Improved Performance: Optimizes application delivery, especially for cloud-based services (SaaS).
  • Increased Agility: Faster deployment of new sites and services.
