Reliable asymmetric path capacity measurement

Existing non-cooperative methods for network capacity measurement are quite restrictive for capacity-asymmetric paths, and their results could be affected by adverse network conditions (e.g., packet delay, packet loss, and packet reordering). In this paper, we propose to use two types of packet pairs---round-trip packet pair and two-way packet pair---and the minimum-delay-difference method for reliable capacity measurement. Our preliminary results show that the new proposal is correct and achieves accurate results even for highly capacity-asymmetric paths.
