1. A method, comprising:

  • receiving network monitoring data for a plurality of internet protocol (“

    IP”

    ) packets, each having been routed along a respective initial path according to a predetermined policy by a routing node in a packet-switched network;

    receiving a proposed policy designed to cause an intended change in routing future IP packets;

    generating a corresponding simulation packet for each of the plurality of IP packets based on the network monitoring data;

    routing each of the simulation packets along a respective simulated path according to the proposed policy to simulate routing the future IP packets;

    determining, for a particular IP packet in the plurality of IP packets, a deviation between the respective simulated path for the corresponding simulation packet and the respective initial path; and

    determining whether to apply the proposed policy to the routing node based on whether the intended change in routing includes the deviation.
