https://www.cisco.com/c/dam/en/us/td/docs/routers/sdwan/migration-guide/cisco-sd-wan-migration-guide.pdfThe component of the Cisco SD-WAN architecture that oversees the control plane of overlay network to establish, adjust, and maintain the connections between the WAN Edge devices that form the Cisco SD-WAN fabric is the vSmart controller.
The vSmart controller is a centralized component of the Cisco SD-WAN architecture that is responsible for managing the control plane of the overlay network. It uses software-defined policies to establish, adjust, and maintain the connections between the WAN Edge devices that form the Cisco SD-WAN fabric. These policies are based on network and application requirements, and they are dynamically updated to ensure optimal network performance and availability.
The vSmart controller is a key component of the Cisco SD-WAN architecture because it provides the intelligence that enables the system to operate in a completely automated and self-configuring manner. It uses secure communication channels to exchange information with the other components of the Cisco SD-WAN architecture, including the WAN Edge devices, vBond orchestrator, and vManage NMS.
In summary, the vSmart controller is a central component of the Cisco SD-WAN architecture that manages the control plane of the overlay network. It uses software-defined policies to establish, adjust, and maintain the connections between the WAN Edge devices that form the Cisco SD-WAN fabric.
