Cisco SD-WAN SEN Components:
Of these four components, the vEdge router can be a Cisco SD-WAN hardware device or software that runs as a virtual machine, and the remaining three are software-only components. The software vEdge router, vManage NMS, and vSmart controller software run on servers, and the vBond orchestrator software runs as a process (daemon) on a vEdge router.
