ABSTRACT:
Communication quality values such as delay times of packets transmitted and received within a packet network are measured, and a threshold value is calculated based on the measured communication quality values. Further, a management reference value is calculated based on the communication quality values of packets whose measured communication quality values are within a range based on the threshold value. A communication state is detected by comparing the measured communication quality values with the management reference value.
