Abstract
A packet reception portion receives packets of user traffic transferred on the network. The received packets are transferred to an address extraction portion via a distribution portion, and the transmission source address and destination address are extracted. Based on these addresses, a packet generation portion generates probe packets the transfer destination of which is the address destination. A packet transmission portion transmits the probe packets to the network. The transmitted probe packets are received as probe response packets by the packet reception portion. The probe response packets received by the packet reception portion are transferred to a result storage portion via the distribution portion. The result storage portion stores transmission source addresses included in the probe packets in a result storage DB.
