  • Independently verifying a transit point in a network environment
    Patent number: 9474040
    Abstract: An example method for independently verifying a transit point in a network environment is provided and includes receiving, at a transit point in a packet network, at least two radio signals from corresponding different radio sources, receiving, at the transit point, a sampling request in an packet message, and transmitting in another packet message a sample of the at least two radio signals such that by comparing the sample with an expected sample, a location of the transit point is determined. The expected sample can comprise another sample of the at least two radio signals that would have been received by the transit point at an expected location at a time of receipt of the sampling request, and if the expected sample matches the sample, the transit point is determined to be at the expected location.
