Abstract:
A method and system of monitoring computer network activity including determining a first phase frequency estimate, associated with a first frequency vector, determined in response to receiving first bits from a first plurality of remote computer network devices. The first bits received from the first plurality of remote devices in response to satisfying a first activity threshold. Also, determining a second phase frequency estimate associated with a second frequency vector and determined in response to receiving second bits from a second plurality of remote devices. The second bits received from the second plurality of remote devices in response to a second activity threshold being satisfied. The second phase frequency estimate determined in response to the first phase frequency estimate exceeding a global threshold. Further, providing a frequency moment Fp in response to the second phase frequency estimate exceeding a refined threshold.
