COMMUNICATION QUALITY ESTIMATION SYSTEM, DEVICE, METHOD, AND PROGRAM

摘要

A communication quality estimation system includes a plurality of devices which perform transmission of packets over a network and a communication quality estimation device. The plurality of devices includes a first device, a second device, and a third device located on the downstream side of the first device and on the upstream side of the second device. The communication quality estimation device compares the number of first packets complying with a first sampling rule out of the packets sent from the first device and the number of second packets complying with the first sampling rule out of the packets sent from the second device and estimates a communication quality in the third device.
