Patent ID: 7864695

Claim:
A traffic load density measuring system measuring traffic load density, comprising: a transmitter connected to a communication network for transmitting a packet; and a receiver connected to the communication network for receiving the packet, and wherein the transmitter comprises: a communication interval acquiring unit that acquires a communication interval of the packet for communication; a detection packet transmission unit that transmits a packet for load density detection at a predetermined transmission interval, in which the transmitted packet for load density detection is provided with transmission information capable of specifying a transmission time, the transmission interval, and a transmission number of the packet for load density detection; and an interval change unit that sets the transmission interval to be a different interval from the communication interval, and the receiver comprises: a reception unit that receives the packet for load density detection; an extraction unit that extracts said transmission information from the packet for load density detection being received; and a measurement unit that measures the traffic load density based on the extracted transmission information, and a delay or lost status of the packet for load density detection.
