Computes all ephemeral runtime state based on configuration from the management plane, disseminates topology information reported by the data plane elements, and pushes stateless configuration to forwarding engines.

The control plane is split into two parts in NSX-T Data Center, the central control plane (CCP), which runs on the NSX Controller cluster nodes, and the local control plane (LCP), which runs on the transport nodes, adjacent to the data plane it controls. The Central Control Plane computes some ephemeral runtime state based on configuration from the management plane and disseminates information reported by the data plane elements via the local control plane. The Local Control Plane monitors local link status, computes most ephemeral runtime state based on updates from data plane and CCP, and pushes stateless configuration to forwarding engines. The LCP shares fate with the data plane element which hosts it.
