Accurate One-Way Delay Estimation With Reduced Client Trustworthiness The requirement for accurate one-way delay (OWD) estimation led to the recent introduction of an algorithm enabling a server to estimate OWDs between itself and a client by cooperating with two other servers, requiring neither client-clock synchronization nor client trustworthiness in reporting one-way delays. We evaluate the algorithm by deriving the probability distribution of its absolute error and compare its accuracy with the well-known round-trip halving algorithm. While neither algorithm requires client trustworthiness nor client-clock synchronization, the analysis shows that the new algorithm is more accurate in many situations.
