摘要： To detect the communication conditions of a communication path set in a packet network such as a VoIP network, a detection packet is periodically transmitted to the communication path and a load packet is transmitted to the communication path. Then, the time and loss conditions regarding a detection packet having passed through the communication path are detected, and changes in delay and jitter conditions and changes in loss rate according to a traffic load are grasped. Changes in the communication conditions of the communication path at high load can be detected while minimizing the occurrence of adverse effects on other communications.

摘要： When simulating communication using a communication network such as a VoIP network, an actual communication state is accurately simulated, and communication is simulated. The distribution of delay times of packets is transformed by a predetermined transformation method, packet transmission timings to which delay times are added, are calculated based on the transformed distribution of delay times and predetermined transmission timings, a determination is made as to whether or not the packet transmission order is changed by the calculated transmission timings to which delay times are added, and, when a determination is made that the packet transmission order is changed, packet transmission timings adjusted so as not to cause a change in the transmission order are derived.

摘要： The traffic load density measuring system includes a transmitter connected to a communication network for transmitting a packet, and a receiver for receiving the packet, in which a packet for load density detection is transmitted and received to measure a traffic load density within a predetermined transmission interval. The transmitter changes a transmission interval of the packet for load density detection, and adds transmission information capable of specifying a transmission time, a transmission interval, and a transmission number of the packet for load density detection to the packet for load density detection to transmit said packet. The receiver receives the packet for load density detection, extracts the transmission information from the packet for load density detection being received, and measures the load density within the predetermined transmission interval based on the extracted transmission information, and a delay or a lost status of the packet for load density detection.
