The vSmart Controller in SD-WAN Deployments

C.

In an SD-WAN deployment, the vSmart controller is responsible for managing and orchestrating the entire SD-WAN fabric. It acts as the brain of the SD-WAN network and provides centralized control and management of the network.

The following are the specific responsibilities of the vSmart controller:

A. Onboard vEdge nodes into the SD-WAN fabric: The vSmart controller is responsible for discovering and authenticating vEdge nodes that join the SD-WAN network. It provides secure device authentication and establishes secure communication channels between vEdge nodes.

B. Gather telemetry data from vEdge routers: The vSmart controller collects real-time telemetry data from vEdge routers, such as traffic statistics, performance metrics, and security information. This information is used to optimize traffic routing and to detect and respond to security threats.

C. Distribute security information for tunnel establishment between vEdge routers: The vSmart controller distributes security policies, such as encryption keys and digital certificates, to vEdge routers for establishing secure tunnels between them. This ensures secure communication between vEdge routers and protects against unauthorized access and data theft.

D. Manage, maintain, and gather configuration and status for nodes within the SD-WAN fabric: The vSmart controller manages and maintains the configuration and status of all nodes within the SD-WAN fabric. It provides a single point of management for the entire network and enables administrators to monitor and troubleshoot the network more easily.

In summary, the vSmart controller is a critical component of an SD-WAN deployment that provides centralized management, control, and security for the network. It enables administrators to simplify network management, optimize traffic routing, and secure network communication.
