ABSTRACT:
A packet communication quality measurement method and system in which two quality measurement devices connected via a packet communication network exchange a probe packet via the network. The packet communication quality is calculated based on the transmission/reception status of the probe packet. Probe packets are intermittently transmitted from one quality measurement device to another via the network at a predetermined interval, and received by the other device. The communication quality of each probe packet is calculated based on the transmission/reception status of the probe packet. The communication quality of user packets is estimated by weighting the communication quality of probe packets in accordance with the number of user packets flowing in a desired measurement direction along the path which connects the quality measurement devices at an interval between transmission of a previous probe packet and transmission of the probe packets.
