A minimum-delay-difference method for mitigating cross-traffic impact on capacity measurement
Edmond W. W. Chan, Xiapu Luo, Rocky K. C. Chang · 2009
The accuracy and speed of path capacity measurement could be seriously affected by the presence of cross traffic on the path. In this paper, we propose a new cross-traffic filtering method called minimum delay difference (MDDIF). Unlike the classic packet-pair dispersion techniques, the MDDIF method can obtain accurate capacity estimate from the minimal possible delay of packets from different packet pairs. We have proved that the MDDIF method is correct and that it takes less time to obtain accurate samples than the minimum delay sum (MDSUM) method. We also present analytical and measurement results to evaluate the MDDIF method and to compare its performance with the MDSUM method.
