Patent ID: 8184553

Claim:
A method for measuring packet transmission quality in a communication network including a packet transmission node and a packet reception node, comprising: providing the packet transmission node with a transmission counter and a measurement packet counter, the transmission counter counting the number of packets transmitted from the packet transmission node to the packet reception node, the measurement packet counter counting the number of measurement packets transmitted from the packet transmission node to the packet reception mode so as to measure transmission quality of packets transmitted from the packet transmission node to the packet reception node; providing the packet reception node with a reception counter counting the number of packets received from the packet transmission node; transmitting, by the packet transmission node, to the packet reception node a measurement packet including a transmission counter read out from the transmission counter and a measurement packet counter value read out from the measurement packet counter; and calculating, by the packet reception node, the number of lost packets or a loss rate of packets on the basis of the transmission counter value obtained from the received measurement packets, the measurement packet counter value obtained from the received measurement packets, and a reception counter value read out from the reception counter.
