Software-Defined Wide Area Networking (SD-WAN) has emerged as a transformative force, leveraging automation to construct resilient, application-aware overlay networks with multiple uplinks. The management of this infrastructure is centralized, orchestrated by a cloud controller—a paradigm shift from legacy networking solutions provided by incumbent service providers.

Despite the myriad of vendors offering SD-WAN solutions, each with their unique deployment strategies and strengths, none have reached the pinnacle of an ultimate solution. The underlying features essential to SD-WAN's functionality and success serve as the cornerstone of its architecture:

Core Features of SD-WAN

  • Built on Linux because the cloud is Linux.

  • Simplified and Optimal Deployment so that less resources are required

  • Cloud-Native Support as the processes for legacy networking deployments are cumbersome

  • Hub-and-Spoke at the Edge, Mesh in the Core. Mesh at the edge is complex and unreliable.

  • Multi-tenant

  • Capabilities where each deployment is not a separate solution architecture

  • Interoperability via APIs providing the ability to customize

  • Scalability with Intel Processor-Based Nodes

  • Advanced Traffic Analytics to determine underlying business efficiency and downtime causation

  • Robust Security Measures and Component Partitioning. Monolithic stacks are a single point of failure!

  • Embrace New Thinking, Not Retrofit Firewalls. Renaming VPNs is not a strategy.

Understanding the Technical Components

  • Data Plane: Throughput, WAN ports, tunneling, path steering, security features, and cloud integration.

  • Overlay: VxLAN technology for tunneling, IPSEC's resource challenges negate its use, and the emergence of Wireguard.

  • Path Resiliency: Seamless path selection, WAN aggregation, bonding, dynamic tunnel creation, and performance-based link switch-over.

  • Control Plane: Site connectivity, Full-Mesh vs. Hub & Spoke, automated traffic engineering, and machine-learning for adaptive connectivity.

  • Management Plane: Cloud-Native management, scalability, visibility, and advanced traffic analytics.

Fusion Broadband South Africa's SD-WAN stands among the innovative solutions that grasp the nuanced technicalities and embody a functional architecture. By embracing the core tenets of SD-WAN and implementing a stable, cloud-centric approach, it redefines networking paradigms for businesses across industries.
