<p>PROBLEM TO BE SOLVED: To provide a datagram transfer device which can perform transfer control at a high speed and requires only a small memory capacity. SOLUTION: An attribute information conversion section 110 individually discriminates corresponding index values Kd, Ks, Kp, and Kt from the attribute information D-Port, S-Port, PID, and TCP of a received datagram at every attribute information. A calling address conversion section 120 converts the calling address SA of the received datagram into an index value Ksa. A destination address conversion section 130 converts the destination address DA of the received datagram into an index value Kda. A selection key preparing section 140 prepares a flow selection key from the index values Kd, Ks, Kt, Kp, Ksa, and Kda. A transfer control deciding section 150 retrieves the executed content of transfer control by using the flow selection key. A transfer control executing section 160 executes the transfer control decided by the deciding section 150.</p> |
