•ABwE is based on the simplest
way of probing (using only Packet pairs)
•Evaluation is based on detailed
technical analysis of how the packets pass via queuing
devices
•Complete path is cascade of
queuing devices with different
capacities
•The separation of probing
packets will happen even if there is
no cross traffic
•The final dispersion PP1
and PP2 is the results of superposition of many
factors
