ABSTRACT:
A method and computer-program product are provided for measuring the Round-Trip Time (RTT) of data flowing thorough a communications network using a single measurement point. The method includes timestamping a first packet traveling past the measurement point and timestamping a second packet traveling past said measurement point. These difference of these two values is the RTT. This RTT can be continuously updated during the life of the connection to provide an evermore accurate RTT measurement. Alternatively, two sub RTTs can be computed and then summed to arrive at the connection's RTT.
