  • determining, by a device in a network, that a particular packet flow in the network is sensitive to packet reordering;

    wherein the device determines that the articular packet flow is sensitive to reordering based on a policy received from a supervisory device;

    determining, by the device, whether a particular packet of the packet flow is to be routed differently than an immediately prior packet in the packet flow, in response to determining that the particular packet flow is sensitive to reordering; and

    marking, by the device, the particular packet as taking a different route than the immediately prior packet in the packet flow, prior to forwarding, the marked packet and in response to determining that the particular packet is to be routed differently than the immediately prior packet in the packet flow.
