METHOD FOR PERFORMING A BANDWIDTH TEST FOR COMMUNICATIONS FROM A FIRST NETWORK STATION TO A SECOND NETWORK STATION OF A COMMUNICATION NETWORK AND CORRESPONDING APPARATUSES FOR PERFORMING THE METHOD STEPS AND CORRESPONDING COMPUTER PROGRAM PRODUCTS

摘要

The disclosure describes a method for performing a bandwidth test for communications from a first network station (20) to a second network station (21) of a communication network. Such bandwidth test is based on the so-called PRM model (in words probe rate model) in which iteratively a train of probe sample packets is transmitted from first station (20) to the second station (21) with a constant packet rate per iteration. The packet rate however is adapted to the available bandwidth on the data pipe per iteration. According to the disclosure the number of probe sample 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. Also 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.
