Abstract: Data of traffic with long-range dependence characteristics is generated by a host terminal and transferred to a memory arranged on a board. The memory stores the traffic data comprising at least one of the number of IP packets output per unit time and total number of bytes, a set value of each parameter of the generated IP packets (i.e., packet length table) and an IP address table. A packet generation section refers to the data in the memory to generate traffic with long-range dependence characteristics at a speed corresponding to a high-speed network. As a result, the behavior of the network at the time of application of the load can be measured before the actual use of the network. According to the present invention, a traffic generation apparatus that can supply the actual network with a load close to the real traffic can be provided.
