Abstract
A flow identifier is described for packet sequences through a secure tunnel of an SD-WAN in a tunnel-less mode. A method includes receiving from a first client packets of a same flow, facilitating a secure tunnel between the first hub and the second hub, assigning a flow identifier to the packets, associating fields of a header of a start packet with the flow identifier, sending the start packet with the flow identifier through the secure tunnel, receiving an acknowledgement of the flow identifier, updating a state of the secure tunnel, removing the associated fields from a header of a second packet to form a reduced packet in response to 10 receiving the acknowledgment, encapsulating the reduced packet in a wrapper that includes the flow identifier, and sending encapsulated reduced packet.
