According to 1, VMware NSX-T Data Center implements three separate but integrated planes:
management, control, and data.
The management plane provides a single point of configuration and REST API entry-points for NSX-T Data Center components.
The control plane is responsible for computing network state based on configuration from the management plane and topology information from transport nodes.
The data plane consists of transport nodes that provide connectivity for workloads and enforce network policies.
