1. A non-transitory computer-readable medium comprising machine readable instructions that, when executed, cause a network device to at least:

  • send a flow of packets from a source endpoint to a destination endpoint by way of a network, the flow of packets being associated with flow identification information;

    obtain network congestion information from a network monitoring service;

    detect that congestion is affecting the flow of packets in the network and determine, based at least in part on the network congestion information, whether the congestion experienced by the flow of packets may be caused by flow collisions; and

    effect a perturbation to a port field in the flow identification information for the flow of packets in response to determining that congestion is affecting the flow of packets in the network and in response to a determination that the congestion may be caused by flow collisions, the machine readable instructions that effect the perturbation being configured to cause the network device to at least;

    detect an interruption in the flow of packets; and

    schedule the perturbation relative to the interruption.
