👻Demystifying the Technical Landscape of Last Mile SD-WAN | Unveiling Its Intricacies & Functionality🚀

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.
