<p><P>PROBLEM TO BE SOLVED: To carry out application analysis, even if there is a packet that cannot be received, by receiving and assembling packets addressed to other hosts on a network. <P>SOLUTION: In a communication recording apparatus 1, a reception control unit 3 connects to a communication network over which application data are divided into a plurality of packets and communicated, and stores received packets in a memory. A TCP analysis unit 4 analyzes connection information of the packets received by the reception control unit 3, and a TCP order control unit 5 determines an order of packets received by the reception control unit 3. When some of the plurality of packets are stored in the memory by the reception control unit 3, an application analysis unit 6 then reads the partial packets from the memory and records part of application data contained in the read partial packets in a recording unit 9, which in turn is an auxiliary storage device, as part of communication history. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
