Which persistent connections does the vBond orchestrator establish?

The vBond orchestrator establishes permanent DTLS or TLS connections to vSmart controllers. This persistent connection allows vBond to securely authenticate and authorize vSmart controllers, and to maintain a continuous communication channel for exchanging control plane information. While vBond helps WAN Edge routers discover vSmart controllers, it does not maintain permanent connections to WAN Edge routers itself; those are temporary for initial authentication. vBond does not use OMP for updates, nor does it maintain the secure connectivity state between vSmart and WAN Edge routers; that is handled by the vSmart controllers and the WAN Edge routers directly.
