1. A method comprising:
receiving, at a system comprising a hardware processor, one-way delay measurements for probe packets in a probe train sent over a network path;
grouping, by the system, the probe packets into a plurality of pairs of probe packets based on the one-way delay measurements that form a bump;
for each respective pair of the plurality of pairs, computing, by the system, a respective noise threshold based on one-way delay measurements of probe packets transmitted after a later-transmitted probe packet of the respective pair, the computing producing noise thresholds for the plurality of pairs;
selecting, by the system, a selected pair of the plurality of pairs according to a comparison of the one-way delay measurements for the probe packets of the plurality of pairs to the noise thresholds; and
estimating, by the system, an available bandwidth on the network path based on transmission times of the probe packets in the selected pair.
