<p>PROBLEM TO BE SOLVED: To provide a flow-detecting device which enables flow detection without such expensive device as CAM, a slow software process, etc., while significantly reducing a memory capacity. SOLUTION: A hash function process part 11 of a flow-detecting device 1 calculates with a hash function f. A flow-detection table, after the hash function calculation, in which priority is stored using a calculated value of the hash function f as a flow number F is registered in a post-hash calculation flow table, housing memory 2 after hash calculation. The flow-detecting device 1 detects flow by referencing the post-hash calculation flow table housing memory 2.</p> |
