the distributed data plane components on the worker nodes. • The network data plane refers to the packet transmit and receive function on every node, especially on worker nodes where the workloads reside management of routes • collects and exports statistics from the data plane The vRouter provides the packet send and receive function for the co-located pods and workloads. It provides the CNI plug-in functionality planes for the host cluster. The Contrail data plane components sit in all nodes and provide the packet send and receive function for the workloads. 11 Figure 3: Single Cluster Deployment Multi-Cluster
