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 a sequence of packets from a first client at the first hub, the sequence of packets each having a same flow, facilitating a secure tunnel between the first hub and the second hub, assigning a flow identifier to the sequence of packets, converting fields from a header of the packet to a metadata supplement to the packet to form a reduced packet, encapsulating the reduced packet in a wrapper that includes the flow identifier, and sending the packet of the sequence of packets from the first hub to the second hub the secure tunnel.
