End-to-end data packet flow control is described for an overlay environment of a wide area network. A method includes detecting an active session of a specific application with a source node and a destination node within an overlay environment, detecting a traffic flow from the source node to the destination node associated with the active session, mapping the traffic flow to a dedicated service processing thread of a network services appliance, mapping an identifier to the dedicated service processing thread, and forwarding the traffic flow to the destination node through the dedicated service processing thread by applying the identifier to the traffic flow.

End-to-end data packets flow control through an overlay environment of a wide area network

A system and a method are described for data packet fragmentation for replicated packet traffic through an SD-WAN. In an example a first packet has an internet protocol identification (IP-ID). The first packet is replicated to create a second packet. The first packet and the second packet are fragmented into fragments for transmission through a tunnel in one or more paths between the source address and the destination address. The IP-ID of the second packet is modified. The fragments of the first packet and the second packet are separately encapsulated. The first and second packet fragments are received through the tunnel at a second node. The second node reassembles the first packet using the first packet fragments and reassembles the second packet using the second packet fragments. The IP-ID of the reassembled second packet is restored to be the IP-ID of the first packet.
