Patent ID: 8160835

Claim:
A method for measuring unidirectional transmission properties and results derivable therefrom in a telecommunications network, comprising: providing a first measuring computer and a second measuring computer; synchronizing in time the first measuring computer and the second measuring computer by a plurality of satellites so that a clock time is continuously transmitted by the plurality of satellites to the first and second measuring computers; transmitting at least one test packet from the first measuring computer to the second measuring computer; recording a departure time of the at least one test packet by the first measuring computer; transmitting the departure time along with the at least one test packet; recording an arrival time of the at least one test packet by the second measuring computer; subtracting the departure time from the arrival time to determine a measuring result; storing the measuring result in a database; determining an actual delay of the at least one test packet, wherein the actual delay of the at least one test packet is equal to subtracting a computer-specific time component constant and a measuring error from the measuring result; interrupting transmission of the at least one test packet if the plurality of satellites includes only one working satellite for a predetermined period of time; generating a status message indicating the transmission interruption of the at least one test packet; and resuming transmission of the at least one test packet when the plurality of satellites includes more than one working satellite.
