    Abstract: 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.
