Title
A new approach for path capacity measurement in Internet
Abstract
The p-pair/train technique estimates the capacity of a path from the dispersion experienced by two/multiple back-to-back packets. The dispersion of packets may follow a complicated multimodal distribution, which causes statistical filtering methodologies and heuristic approaches (e.g., pathrate) to be inaccurate in heavily-loaded cases. This paper analyzes the noise characteristics in the path capacity measurement, and elaborates on the distribution of capacity estimates. Based on this analysis, a new algorithm called LMSA (Local Modes Statistical Algorithm), and its enhancement (LMSA+) are presented. Using multiple distributions of capacity estimates obtained by variable-sized probing p-pairs, LMSA+ only picks out the local modes that locates at fixed positions, and selects the minimum of these modes as the path capacity. Simulation results demonstrate that, compared with pathrate, LMSA+ is more accurate in heavily-loaded paths or paths with relatively large bottleneck bandwidth values, and is more robust to the dynamic cross traffic load.
