1. A method for determining latency of a physical network path in a network, the method comprising:

  • receiving, by a virtual network controller, a plurality of messages from a plurality of network devices in a network, wherein each of the messages includes (1) a packet signature comprising a hash of an invariant portion of an original packet that uniquely identifies the original packet, (2) an identifier of one of the plurality of network devices from which the respective message was received, and (3) a timestamp indicating a time an original packet was processed by the network device from which the respective message was received;

    identifying, by the virtual network controller, two or more of the plurality of messages having a common packet signature;

    determining, by the virtual network controller, a latency of a physical network path in the network based on analysis of contents of the identified messages having a common packet signature.
