<p><P>PROBLEM TO BE SOLVED: To efficiently generate flow information. <P>SOLUTION: In a flow information generator, a plurality of packets are collected and stored, and the stored plurality of packets are summed up, based on specified attributes to generate flow information which indicates the communication state of flows that are a group of packets having the same attribute. The flow information is constituted of attribute information which is included in each of the plurality of packets and specifies attributes of the packets, and a non-attribute information which is linked to each of the plurality of packets and is necessary for generating flow information. The flow information generator has a storage part, and a flow information generation management part that stores collected packets into the storage part, overwrites a memory area of the memory area storing the collected packets, which stores information other than attribute information, with non-attribute information, corresponding to the collected packets to store attribute information and non-attribute information with linking them into the memory area storing the collected packets. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
