Short - Cisco SD-WAN

Cisco SD-WAN is an enterprise grade WAN architecture overlay that enables digital and cloud transformation for enterprises. It integrates routing, security, centralized policy, and orchestration into large-scale networks. Here are some benefits of Cisco SD-WAN: Centralized network and policy management, seamless connectivity into the public cloud, optimization of SaaS applications, and also rich analytics with visibility into applications and infrastructure.

Why would we use Cisco Catalyst SD-WAN solution? There are a few reasions those being, secure automated WAN, application performance optimization for remote uses, secure direfct internet access as well as multicloud connectivity.

The Cisco SD-WAN solution is made up of four different planes. These are:

Orchestration Plane - Assists in automatic onboarding of SD-WAN routers into the SD-WAN overlay.
Management Plane - Responsible for central configuration and monitoring.
Control Plane - Builds and maintains the network topology and makes decisions on where traffic flows.
Data Plane - Responsible for forwarding packets based on control plane decisions.
