Packet communication quality measurement method and system

摘要

In a packet communication quality measurement method in which two quality measurement devices connected via a packet communication network exchange a probe packet via the packet communication network and 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 the other quality measurement device via the packet communication network at a predetermined interval, and received by the other quality measurement device. The communication quality of each probe packet is calculated based on the transmission/reception status of the probe packet. The communication quality is weighted in accordance with the number of 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 packet. The packet communication quality between the quality measurement devices is calculated from communication qualities which are calculated and weighted for a plurality of probe packets. A packet communication quality measurement system is also disclosed.
