A relay device (1) includes a plurality of network processing units (200-1˜200-N) having the same function and structure. A session management unit (202-1) in a certain network processing unit (e.g. 200-1), when receiving a packet from an external network through an IF unit (e.g. 204-1-1) in the same processing unit, searches a session table (230-1) for IF specifying information indicative of an IF unit as an output destination determined for a session to which the above packet belongs. When the above IF specifying information indicates an IF unit (e.g. 204-N-M) in other network processing unit (e.g. 200-N), a packet processing unit (201-1) transfers the above IF specifying information and the above packet to the network processing unit (200-N) through a switch unit (300). A packet processing unit (201-N) in the network processing unit (200-N) outputs the above packet to the IF unit (204-N-M) represented by the IF specifying information.
A packet relay device which relays a packet, comprising
A packet relay device which relays a packet, comprising:
A packet relay method in a packet relay device having a plurality of network processing units, wherein
A program for causing a computer to function as a network processing unit as a component of a packet relay device having a plurality of network processing units, which causes said computer to function as a means that, when receiving a packet from an external network, on condition that an IF unit as an output destination determined for a session to which the packet belongs exists in other network processing unit, transmits said packet and IF specifying information specifying said IF unit to said other network processing unit and when receiving a packet and IF specifying information from other network processing unit, outputs said packet to an IF unit specified by said IF specifying information.
