    摘要: A test packet transmitting apparatus transmits respective test packets including different pieces of identification information to a repeating installation. The repeating installation makes a predetermined number of copies of each test packet received from the test packet transmitting apparatus to be transmitted to a test packet receiving apparatus, and determines the predetermined number of copies as a population to measure a communication quality. The test packet receiving device counts the received test packets according to each type of identification information.

    摘要: In order to preliminarily perform a load test or the like of an IP network, a test apparatus instructs a test packet transmitting device to transmit a test packet having a specified multicast address and instructs a test packet receiving device to receive the test packet of the multicast address. The test apparatus further instructs a first relay device to relay the test packet of the multicast address and instructs a second relay device to perform a route optimization excluding processing. The test packet receiving device requests the second relay device to transfer the test packet of the multicast address when the test packet receiving device has received the instruction to receive the test packet.

    摘要: A plurality of traffic monitoring apparatuses and an entry managing apparatus common to the traffic monitoring apparatuses are provided in a network. In the traffic monitoring apparatus, a packet receiving unit extracts a source IP address, destination IP address, and a TTL count to be registered in an entry registering unit as an entry. A destination-address counting unit counts the number of entries having the same source IP address and the same TTL count. A TTL counting unit counts the number of entries having the same source IP address and the same destination IP address, and counts a largest TTL count. An entry reporting unit reports a TTL count or a largest TTL count to the entry managing apparatus. The entry managing apparatus identifies a traffic monitoring apparatus that has reported a TTL count having the largest value or a largest TTL count having the largest value, as an origin of an abnormality.
