Abstract
An approach is provided where incoming packets are received at a data plane and header fields are extracted from the incoming packet. Flows from a flow data store are matched with the extracted header fields from the incoming packet. Packet descriptor data associated with the incoming packet is marked in the selected incoming packet forming a marked ingress packet with marking performed when the matching fails. The marked ingress packet is forwarded to a control plane that retrieves flow-related data related to the marked ingress packet and updates the marked packet descriptor data using the retrieved flow-related data, thereby forming an updated marked packet. The control plane passes the updated marked packet back to the data plane for further processing to update the flow data stored in the flow data store.
