<p>PROBLEM TO BE SOLVED: To accelerate transfer control of a datagram transfer system. SOLUTION: An address retrieving unit 111 of an attribute information retrieving unit 110 retrieves a combination of attribute information used for a transfer control by using a destination address DA of the datagram, and reads a bit map indicating the combination from an information table 112. An identifying key forming unit 120 reads a value of attribute information indicated by the map from the datagram, and forms a flow identifying key corresponding to the value of the attribute information. A hash retrieving unit 131 of a transfer control deciding unit 130 retrieves an index corresponding to the key, and reads the action corresponding to the index from an action table 132. A transfer control executing unit 140 executes the action decided by the unit 130.</p> |
