vManager - is the controller and cisco considers it the management plane vSmart - is the control plane. vEdge is the data plane. vBond is the orchestrator plane, and according to cisco it authenticates the vSmart controllers and the SD-WAN routers and orchestrates connectivity between them. It is the only device that must have a public IP address so that all SD-WAN devices in the network can connect to it. A vBond orchestrator is an SD-WAN router that only performs vBond orchestrator functions.
Great write up, thank you
Cisco SD-WAN has been rebranded to Cisco Catalyst SD-WAN. As part of this rebranding, the vManage name has been changed to SD-WAN Manager, the vSmart name has been changed to SD-WAN Controller, and the vBond name has been changed to SD-WAN Validator. Orchestration Plane Bringing the WAN Edge into the Overlay In order to join the overlay network, a WAN Edge router needs to establish a secure connection to the SD-WAN Manager so that it can receive a configuration file, and it needs to establish a secure connection with the SD-WAN Controller so that it can participate in the overlay network. The discovery of the SD-WAN Manager and Controller happens automatically and is accomplished by first establishing a secure connection to the SD-WAN Validator.
