METHOD FOR PERFORMING A BANDWIDTH TEST FOR COMMINICATIONS 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

A method for performing a bandwidth test for communications from a firstnetwork station to a second network station of a communication network isbased onthe probe rate model (PRM) in which iteratively a train of probe samplepackets istransmitted from the first station to the second station with a constantpacket rate periteration. The packet rate is adapted to the available bandwidth on the datapipe periteration. According to the disclosure the number of probe packets per trainof probesample packets is varied with the available bandwidth per iteration. Thisincreasesthe accuracy of the test, in particular, in the range where a high data rateis availableon the data pipe. A step decreasing factor (SDF) is applied with which theperformance test is improved. Such step decreasing factor is dependent on thenetwork jitter and further improves the performance of the test.
