摘要： PROBLEM TO BE SOLVED: To provide a traffic recorder for inexpensively recording traffic data before and after a characteristic event. SOLUTION: The traffic recorder includes a data reception part for receiving traffic data, a damp file recording part being a nonvolatile recording region, and a cache part for dividing the received traffic data on a predetermined time basis to temporarily keeping, as cache data, the divided traffic data, and is used for recording the traffic data. The traffic recorder further includes a cache management part configured to identify cache data with traffic data from reception of a detection notice to a predetermined time ago recorded therein from among cache data in the cache part when receiving the detection notice for notifying that a predetermined event has occurred in the traffic data, and record the identified cache data in the damp file recording part by being related to the detection notice.

摘要： PROBLEM TO BE SOLVED: To provide a packet route tracing system for detecting an illegal packet in an early stage, and for understanding an organization to which the transmission source of an illegal packet is belonging. SOLUTION: This packet route tracing system for specifying the transmission source of a packet based on digest information including the reception time of a packet flowing through a network and a foot mark value as a hash value calculated by inserting a fixed value into a part which changes via a router in an IP header includes: an illegal packet detection sensor 21Z for collecting a packet flowing through the network, and for transmitting data including the detected digest information of the illegal packet; a trace back cooperation device 22 for, when receiving the data including the digest information of the illegal packet, transmitting retrieval request data including the digest information; and trace back devices 23A to 23C for specifying the transmission source of the illegal packet based on the digest information included in retrieval request data received from the trace back cooperation device.
