摘要：
A method for evaluating quality-of-service in packet switching network uses an evaluation signal with a frequency component that changes continuously with a lapse of time. The evaluation signal is a time stretched pulse, and wherein the method includes a step of transmitting the time stretched pulse to at least one packet switching network, a step of receiving the time stretched pulse passed through the at least one packet switching network, and a step of comparing the transmitted time stretched pulse with the received time stretched pulse.
