摘要： PROBLEM TO BE SOLVED: To prevent the occurrence of packet loss in a network containing redundant communication equipment. SOLUTION: If a switching request message is received which requests that communication destination should be changed from first communication equipment to second communication equipment considered as an alternative of the first communication equipment, a changing means for communication changes the communication destination from the first communication equipment to the second communication equipment. A reception means receives reception history showing packets received by the first communication equipment. A retransmission control means determines packets which the first communication equipment does not receive as an object of retransmission, based on a result of comparison between the reception history and transmission history showing packets transmitted to the first communication equipment. A transmission means transmits packets determined as the object of retransmission to the second communication equipment. COPYRIGHT: (C)2011,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a packet transmitting/receiving system, packet transmitting/receiving apparatus and packet transmitting/receiving method, wherein a replay attack check can be appropriately executed. SOLUTION: A packet transmitting apparatus uses the same encryption key for packets, to which different QoS priorities have been set, to encrypt the packets and transmits the encrypted packets after giving the packets a series of sequence numbers which are different by QoS priority set to the packets. A packet receiving apparatus then stores a history of sequence numbers given to the packets received from the packet transmitting apparatus by priority, when a packet is received from the packet transmitting apparatus, identifies a sequence number given to the received packets and determines whether or not the received packet has been received by collating the sequence number with the history stored in a storage section correspondingly to the QoS priority set to the received packet. If it is determined that the packet is yet to be received, the packet receiving apparatus then uses the same decryption key for the packets, to which different QoS priorities have been set, to decrypt the packets.

摘要： PROBLEM TO BE SOLVED: To specify a cause of a failure resulting from configuration of a monitored device so as to prevent the failure resulting from the configuration of the monitored device. SOLUTION: A maintenance center (OPE) acquires, from each radio network controller (RNC), configuration information such as the number of versions of software and the number of versions of hardware of each card constituting the RNC, and accumulates configuration information on the card. The OPE acquires failure information from an RNC where the failure is generated, and accumulates failure information on the RNC. The OPE analyzes the cause of the failure, based on the accumulated configuration information and the accumulated failure information, and specifies a card to be the cause of the failure, the version number of software and the version number of hardware of the card. The OPE notifies a maintenance staff of the cause of the failure for preventive maintenance. In the RNC where the failure is generated, other RNC which is under operation or not under operation, having the cause of the same failure, separation of a failure part and switching to redundant configuration are performed.
