Some embodiments provide a data-plane forwarding circuit that can be configured to learn about a new message flow and to maintain metadata about the new message flow without first having a control plane first configure the data plane to maintain metadata about the flow. To perform its forwarding operations, the data plane includes several data message processing stages that are configured to process the data tuples associated with the data messages received by the data plane. In some embodiments, parts of the data plane message-processing stages are also configured to operate as a flow-tracking circuit that includes (1) a flow-identifying circuit to identify message flows received by the data plane, and (2) a first set of storages to store metadata about the identified flows.
