Abstract

QoS-support technology in networks is based on measuring QoS metrics which reflect a magnitude of stability and performance such as delay, delay variation, available bandwidth and packet error rate and so on. The measurement of one-way delay essentially requires a guarantee of clock synchronization between end-to-end hosts. However, the hosts in networks have a relative or absolute difference in clock time by reason of clock offsets, clock skews and clock adjustments. In this paper, we propose theory and method of estimating one-way delay and clock offset between end-to-end hosts using our proposed theorem, which is derived from a relationship between one-way delays, one-way delay variations and round-trip times.
