1. A method for generating entropy values for packets in an overlay network existing on top of an underlay network, comprising:

  • generating a first entropy value for each packet in a first group of packets received in a sequence of packets from a host;

    detecting an idle amount of time between a first time when a last packet of the first group of packets in the sequence of packets is received from the host and a second time when an initial packet of a second group of packets in the sequence of packets is received from the host; and

    upon determining that the idle amount of time is greater than a first threshold;

    generating a second entropy value for each packet in the second group of packets,wherein the second entropy value is different from the first entropy value;

    inserting the second entropy value in an outer header of each packet in the second group of packets; and

    after inserting the second entropy value in the outer header of each packet in the second group of packets, transmitting the second group of packets to the underlay network.
