1. A method comprising:

  • monitoring, by a network monitoring device, a plurality of nodes in a data center network;

    determining, by the network monitoring device, one or more latency distributions of response times for messages exchanged between pairs of nodes of the plurality of nodes;

    determining a network topology for the plurality of nodes consistent with the one or more latency distributions, the network topology includes one or more communication links interconnecting nodes of the plurality of nodes and a relative position for each node of the plurality of nodes;

    determining a representative response time for each communication link of the one or more communication links based on the one or more latency distributions;

    comparing, by the network monitoring device, a current response time for at least one message exchanged between one pair of nodes to the representative response time for the communication link interconnecting the one pair of nodes; and

    identifying, by the network monitoring device, a network anomaly when the current response time deviates from the representative response time for the communication link interconnecting the one pair of nodes by a threshold amount.
