• Add additional fields on TransferRequest and TransferProcess
• Dataplane registration
• Async Prepare
• Async Start
• Add name/description/labels to DataPlaneInstance
• Data plane availability check
• Dataplane Signaling Protocol DataFlowController

• Authentication between CP and DP
• refactor: inline DataPlaneManager
