1. A method comprising:

  • determining a distance of a first segment of a network established between a content source and a sink;

    determining whether the distance is within a predefined proximity threshold associated with the content propagation limitations;

    in response to determining that the distance is within the predefined proximity threshold, determining a first round trip time associated with the first segment;

    determining a total round trip time of the network between the content source and the sink;

    calculating a second round trip time associated with at least a second segment of the network, wherein the calculation is made based on a difference between the total round trip time and the first round trip time;

    comparing the second round trip time with a round trip time threshold; and

    authorizing content propagation over the network in response to a determination that the second round trip time is lower than the predefined round trip time threshold.
