Which SD-WAN plane builds and maintains the network topology and makes traffic-flow decisions?

The control plane, handled by vSmart controllers, is responsible for building and maintaining the network topology. It exchanges routing information (like OMP routes) and policies, making decisions about traffic flow based on these policies. It dictates how data packets should be forwarded across the SD-WAN fabric. The data plane carries user traffic and enforces the policies set by the control plane. The orchestration plane (vBond orchestrator) helps devices discover each other and establish secure connections. The management plane (vManage) provides a centralized interface for configuring, monitoring, and troubleshooting the SD-WAN network.
