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 achieve a high quality traffic service based on user parameters by using leaky packet algorithm. SOLUTION: A leaky packet counter section 31 adds an output rate to a count change value C2 for each one-cell slot time and calculates a count C1 by subtracting a full rate from the sum when receiving a valid cell output request. An upper limit calculation section 34 calculates an upper limit of the count C1. A count change section 32-1 carries out count change processing in which the count C1 is changed to the upper limit when the count C1 is the upper limit or over or no count is changed when the count C1 is less than the upper limit. A comparison section 33 validates an output timing signal when the count change value C2 is an output reference value or over or invalidates the output timing signal when the count change value C2 is less than the output reference value.
