Extracting the independence signature from packet pair dispersion data in a closed-loop system for end-to-end bandwidth probing

A receiver-based end-to-end scheme for packet-pair end-to-end probing is explored. Dispersion data collected by an agent process at the receiver end of the monitored path is reported back to the controlling manager process at the transmitter via the return path allowing the inter-packet gaps to be dynamically adjusted for optimum measurement. We concentrate particularly on the "independence signature" monitored through the "long" inter-packet gaps (between successive packet pairs) and compared with the corresponding feature in the "short" inter-packet data. A system of dynamic closed-loop monitoring is devised which correctly identifies the narrow-link bottleneck.
