摘要： In order to preliminarily confirming whether or not a protection route to be switched over can be safely switched over during a working route being used in a unicast or multicast mode. a notification of communication confirmation/quality confirmation or multicast communication confirmation is received from a manager device is received. When the received unicast or multicast packet does not include an confirmation identifier instructed by the notification while the received unicast or multicast packet includes a destination network or multicast address instructed by the notification, the received packet is mirrored and the confirmation identifier is set in a predetermined area within a header of the packet to be transferred to a preselected protection route. When the received packet includes the destination network or multicast address and the confirmation identifier instructed by the notification, the manager device is notified of a result of the communication confirmation/quality confirmation and the packet is transferred to the protection route.

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 network verification system verifies a network to which a relay apparatus relays a packet. A test management apparatus includes a condition acquiring unit to acquire verification conditions which contain an unused network address as a test target and a registering unit to register, in an address resolution table of the relay apparatus, an entry in which the unused network address contained in the acquired verification conditions is associated with a physical address of the testing apparatus. A testing apparatus includes a test packet transmitting unit to transmit, when instructed by the test management apparatus, the plurality of test packets to form a plurality of connections based on the verification conditions, a test packet receiving unit to receive the plurality of test packets and a measuring unit to measure communication qualities with respect to the respective connections of the plurality of test packets.

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.

摘要： A monitoring apparatus and apparatuses to be monitored each have an address holding unit which holds the address of a group to which each apparatus belongs. A data frame to be transmitted between the monitoring apparatus and each of the apparatuses to be monitored includes an identifier which specifies communication between two apparatuses or group broadcast. When the identifier specifies the group broadcast, a group address is put in the data frame. In this manner, a large number of apparatuses which form a large-scale network can be divided into groups, and the group broadcast can be carried out when a plurality of monitoring apparatuses are used for monitoring the apparatuses, thereby eliminating the need of polling.
