This paper reports the basic analysis for constructing a method of estimating the one-way delays under delay asymmetry and unknown relative clock offset. This estimation method requires to perform a handshake by transmitting one packet along each of the two uni-directional paths. The sending and receiving times of a packet are measured at the sender and the receiver, respectively, according to the...
Estimating the relative clock offset under asymmetric one-way delays is a hard problem. This paper reports the theoretical fundation for estimating the relative clock offset between a pair of master and slave clocks. The two clocks are equipped on a pair of nodes that are connected by a bi-directional connectivity with asymmetric one-way delays. The estimation requires the two nodes to perform a handshake...
This paper describes an efficient method of estimating the ratio of clock frequency between two clocks used at the two end nodes of a one-way path. This estimation method relies on the local time measurements on the packets in a data stream going from a source node to a sink node. The time durations between adjacent packets are measured at both the source and the sink nodes according to the local...
This paper describes a method of estimating the effective bandwidth through modeling the tail probability of one-way cumulative variable delays. In order to estimate the effective bandwidth of a fixed one-way path, a sequence of probing packets are sent from a source to a sink along the one-way path. The one-way cumulative variable delays are first estimated based on the local time measurements made...
