As the Internet is shifting towards a reliable QoS-aware network, accurately synchronized clocks distributed on the Internet are becoming more significant. The network time protocol (NTP) is broadly deployed on the Internet for clock synchronization among distributed hosts, but is weak in asymmetric paths, i.e., it cannot accurately estimate the clock offset between two hosts when the forward and backward paths between them have different one-way delays. In this paper, we focus on estimating the offset and skew of a clock from one-way delay measurement between two hosts, and propose an idea for improvement of such estimations, which reduces estimation errors when the forward and backward paths have different bandwidths, a major factor in asymmetric delays
