Cisco SDWAN adopts a cloud based solution, it consists of vOrchestrator, vManage, vSmart and vEdge.

• vOrchestrator is responsible for launching all controllers VMs in the cloud.

• vManage is the management plane for the overall SDWAN solution. It uses netconf/YANG to talk to vEdge devices.

• vSmart is the control plane for the overall SDWAN solution. It talks to the vEdge device, acts as the route reflector, key reflector, and policy engine.

• vEdge is the data plane of the overall SDWAN solution. The IR8100 platform talks to vSmart, vManage, as part of the SDWAN network.
