  • Estimating round trip time of a network path
    Patent number: 8385227
    Abstract: A base round trip time (RTT) for a path in a network is determined. The RTT along a network path between a source node and a destination node is measured one or more times. A sample set of fitting parameters based on a distribution of historical queue delays is obtained. A Monte Carlo simulation is performed using the fitting parameters in the sample set to generate a distribution of queue delays for the measured network path. A base RTT for the network path is determined using the measured RTT and the distribution of queue delays.
