COMMUNICATION PATH CONTROL SYSTEM, PATH CONTROL DEVICE, COMMUNICATION PATH CONTROL METHOD, AND PATH CONTROL PROGRAM
First Claim
1. A communication path control system comprising:
- a packet transmitting device for transmitting a received packet based on a packet transmission rule which is a rule defining a transmission method of the packet; and
a path control device for controlling a communication path of the packet, by instructing the packet transmitting device to apply the packet transmission rule,wherein the packet transmitting device includesa process querying unit for querying the path control device about a process for the received packet, andwherein the path control device includesa packet transmitting device determining unit for determining a packet transmitting device that is applied the packet transmission rule decided according to the packet, based on whether or not the query about the process for the packet comprises a first-time query, when receiving the query about the process for the packet from the packet transmitting device.

6. A path control device comprising
a packet transmitting device determining unit for, when receiving a query about a process for a packet from a packet transmitting device that transmits a received packet based on a packet transmission rule which comprises a rule defining a transmission method of the packet, determining a packet transmitting device that is applied the packet transmission rule determined according to the packet, based on whether or not the query about the process for the packet is a first-time query.

7. A communication path control method wherein a packet transmitting device for transmitting a received packet based on a packet transmission rule which comprises a rule defining a transmission method of the packet queries a path control device for controlling a communication path of the packet, about a process for the received packet, and
wherein, when receiving the query about the process for the packet from the packet transmitting device, the path control device determines a packet transmitting device that is applied the packet transmission rule determined according to the packet, based on whether or not the query about the process for the packet comprises a first-time query.

10. A computer readable information recording medium storing a path control program that, when executed by a processor, performs a method for:
when receiving a query about a process for a packet from a packet transmitting device that transmits a received packet based on a packet transmission rule which comprises a rule defining a transmission method of the packet, determining a packet transmitting device that is applied the packet transmission rule determined according to the packet, based on whether or not the query about the process for the packet comprises a first-time query.
