PROBLEM TO BE SOLVED: To reduce the load of learning processing and aging processing.SOLUTION: A packet transmission device includes: a table which stores an entry containing information related to a packet transmission source; a transfer unit which transfers the packet addressed to the packet transmission source on the basis of the table; a learning unit which performs learning processing for registering the entry containing the information related to the received packet transmission source in the table when the entry is not found in the table, and performs learning processing for updating the entry when the entry is found in the table; an aging unit which deletes an entry which has not been updated for a prescribed period from the table; a thinning unit which thins out the packet identified by a prescribed identifier during a time zone determined on the basis of the information indicating the reception state of the packet identified by the prescribed identifier from the learning processing; and a setting unit which sets the packet identified by the prescribed identifier during the time zone as an object not subjected to aging processing.SELECTED DRAWING: Figure 10 |
