The vCloud NFV Edge Reference Architecture network solution consists of separate orchestration, management, control, and data planes.
Management Plane: This plane is responsible for central configuration and monitoring. The management plane assists in the automatic onboarding of CE/PE routers into the NSX-T Edge T0/T1 overlay.
Control Plane: This plane builds and maintains the network topology and makes decisions on traffic flows.
Data Plane: This plane is responsible for forwarding packets based on decisions from the control plane.
The WAN connectivity between Central and Edge sites is beyond the scope of this reference architecture; customers need to ensure connectivity between the two sites. All Edge Sites are connected to its respective aggregation site which is the corresponding Core data center for the region.
