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.

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 and facilitating a secure tunnel between the first hub and the second hub. A flow identifier is assigned to the sequence of packets. Fields of a header of a start packet of the sequence of packets are associated with the flow identifier and the associated fields are removed from a header of a second packet of the sequence of packets to form a reduced packet. The reduced packet is encapsulated in a wrapper that includes the flow identifier, and the encapsulated reduced packet of the sequence of packets is sent from the first hub to the second hub through the secure tunnel.

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.

Abstract: A flow identifier is described for packet sequences through a secure tunnel of an SD-WAN and an error message for recovering the flow. A method includes receiving a sequence of packets, facilitating a first secure tunnel between a first hub and a second hub, assigning a first flow identifier to the sequence of packets, encapsulating a first start packet, the wrapper including the first flow identifier, sending the encapsulated first start packet to the second hub through the first secure tunnel, receiving an error message from the second hub, the error message including the first flow identifier and an error code, facilitating a second secure tunnel, assigning a second flow identifier, encapsulating a second start packet, the wrapper including the second flow identifier, and sending the encapsulated second start packet through the second secure tunnel.
