Abstract
A method for performing a bandwidth test for communications from a first network station to a second network station of a communication network is based on the probe rate model (PRM) in which iteratively a train of probe sample packets is transmitted from the first station to the second station with a constant packet rate per iteration. The packet rate is adapted to the available bandwidth on the data pipe per iteration. According to the disclosure the number of probe packets per train of probe sample packets is varied with the available bandwidth per iteration. This increases the accuracy of the test, in particular, in the range where a high data rate is available on the data pipe. A step decreasing factor (SDF) is applied with which the performance test is improved. Such step decreasing factor is dependent on the network jitter and further improves the performance of the test.
