# 👻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.
