NSX-T on VxBlock 1000 implements a fully distributed control plane architecture, divided between the Central Control Plane (CCP) on the AMP Platform and the Local Control Plane (LCP) resident on the Host Transport Nodes and Edge Transport Nodes. A Transport Node is a device that is part of the data plane and prepared for NSX-T. It participates in traffic forwarding. Examples of Transport Node devices are hosts operating in the Compute cluster and the Edge cluster.
Figure 4. Distributed architecture
This distributed architecture is what allows NSX-T to scale across thousands of heterogeneous endpoints, by considerably reducing the overhead on the CCP.
